2 Overview


2 Overview

2.1 Product overview

The modular structure of the valve manifold enables you to match it optimally in your machine or sys

tem.

The manifold sub-bases of the valve manifold provide the common ducts for the supply and exhaust air.

Working lines 2 and 4 are provided for each valve position on the individual manifold sub-bases. The

valves are supplied with operating pressure and the valve exhaust air is dissipated via the common

ducts of the manifold sub-bases and the ports in the end plates.

The pilot pressure is supplied via port 14 of the left end plate.

The function range at each valve position can be extended by means of additional vertical stacking

components (e.g. exhaust air flow control or pressure regulation).

Depending on the manifold sub-bases used, the valve manifold is available with 1, 2, 3 … 16 valve posi

tions (� Section 2.3).

2.2 Overview of variants

The valve manifold is available in the sizes 18 mm und 26 mm. An intermediate plate is required to com

bine the two widths on one valve manifold.

2 Overview


2.3.1 Valves

The valve manifold can be equipped with 2x 3/2-way valves (standard and reversible), 5/2-way valves

(monostable and bistable) and 5/3-way mid-position valves.

All 5/2-way valves and 5/3-way mid-position valves can be used in all operating modes:

– standard operation

– reversible operation

– low pressure operation

– vacuum operation

Identification of the valves

The valves on the valve manifold are labelled with type codes. The type codes are printed on the re

verse sides of the valves. An identifier within the type code indicates the valve function. For example,

the identifier T32C in the type code VSVA-B-T32C-AZH-A1-1-R2 means that this valve consists of two,

normally closed monostable 3/2-way valves. You can identify the valve function with the aid of the fol

lowing table (� Tab. 2.2). In the sales documentation and in the Festo Configurator, the valves are

marked with an ID code.

Tab. 2.2 Identification of the valve function in the type code

5/2-way valves with switching position sensing

The monostable 5/2-way valves with ID code SO or SQ (width 26 mm) have switching position sensing.

An inductive sensor (N/C contact) monitors the neutral position of the piston spool. The sensor has a

PNP or an NPN output.

Manual override (MO)

The manual override is mainly used when commissioning the pneumatic system in order to check the

functionality and mode of action of the valve or the valve-actuator combination.

The manual override enables the valve to be switched in a not electrically activated, de-energised

status. Only the compressed air supply needs to be switched on.

There are different MO variants, dependent on the valve type.

Tab. 2.3 Manual override variants

Operation of the manual override � Chapter 4.3.

Further information on the valves � Appendix B.

2.3.2 Pilot control of the solenoid coils

The type of pilot control (internal or external pilot air) depends on the type of valve. Valves for operation

with external pilot air are identified with a Z in the type code, e.g. VSVA-B-T32C-AZH-A1-1-R2.

2.3.3 Pressure zone separation

The valve manifold can be fitted with pressure zones:

– A maximum of 2 pressure zones can be implemented if only one size is used.

– If sizes 18 mm and 26 mm are combined, a maximum of 3 pressure zones can be implemented.

The pressure zones are formed via special seal plates, which are inserted in the ducts (� Fig. 2.2).

The following ducts can be separated with the seal plates:

– supply duct (1)

– exhaust duct (3)

– exhaust duct (5)

In the valve manifold, external pilot air is fed in via the end plates. Pressure zone separa

tion of pilot ducts 12 and 14 is not possible.

F1B1 X Flow control plate for restricting the exhaust in ducts 3 and 5

Tab. 2.7 Identification of the vertical stacking component in the type code

2 Overview


Pressure regulator plates

P pressure regulator

ID code ZF, ZA

Mode of operation The pneumatic pressure regulator regulates the pressure in front of

the valve in channel 1 (P). This means that ducts 2 and 4 have the

same regulated pressure. During venting, the exhaust flow in the

valve is from duct 2 to duct 3 and from duct 4 to duct 5

Advantages – The pressure regulator is not affected by exhausting, since the

pressure is regulated upstream of the valve.

– The pressure regulator can always be adjusted, because the

pressure from the valve manifold is always present.

Application examples – An equal initial pressure is required at working lines 2 and 4.

– A lower initial pressure (e.g. 3 bar) is required than the operating

pressure present at the valve manifold (e.g. 8 bar).

Tab. 2.8 P pressure regulator

AB pressure regulator

ID code ZI, ZD

Mode of operation The AB pressure regulator regulates the air pressure in ducts 2 (B)

and 4 (A) after the pressure medium has passed through the valve.

During venting, the exhaust flow is from duct 2 to duct 3 and from

duct 4 to duct 5 via the valve and the pressure regulator.

Restrictions – The exhaust flow is restricted by the pressure regulating valve.

– The pressure regulator cannot be adjusted in the exhaust posi

tion. For example, the pressure regulator for duct 4 cannot be

adjusted when the valve is pressurised in the switching position

from duct 1 to duct 2 and exhausted from duct 4 to duct 5.

Application examples – Two different initial pressures are required at connections 2 and

4 instead of the operating pressure of the valve manifold.

– Use of the reversible pressure regulator is not possible. For ex

ample, when 2x 3/2-way valves with ducted pilot exhaust air

82/84 or a flow control plate is used.

Tab. 2.9 AB pressure regulator

The following example shows the following switching position:

The supply air is passed from duct 1 through the pressure regulator plate and the valve to the pressure

regulator B, where it is regulated and then passed to port 2 of the manifold sub-base. The exhaust air is

passed via duct 4 to pressure regulator A and then via the valve to duct 5.

Fig. 2.3 AB-pressure regulator

Reversible AB pressure regulator

ID code ZJ, ZE

Mode of operation With the reversible pressure regulator, the supply air (duct 1) is split

and routed directly to both pressure regulators. In each case the

regulated air is present in ducts 3 and 5 on the valve. The valve is

thus operated reversibly (� Fig. 2.4).

This means:

– Duct 3 routes the initial pressure to port 2

– Duct 5 routes the initial pressure to port 4.

Advantages compared to the

AB pressure regulator

– Faster cycle times

– 50% higher exhaust flow rate, as air is not vented via the

pressure regulator. The load on the pressure regulator is also

reduced.

– No quick exhaust valves are required. The exhaust air is ducted

completely via the valve manifold.

– Operating pressure is always present at the pressure regulator,

as the pressure is regulated upstream of the valve. That is, both

pressure regulators can always be adjusted simultaneously and

independently of the valve switching position. For the AB

pressure regulator, the valve must switch for this

2 Overview


Reversible AB pressure regulator

Disadvantages compared to

the AB pressure regulator

– No use of 2x 3/2-way valves (ID code H, K and N) is possible in

combination with ducted pilot exhaust air 82/84, since reversible

pressure is present at the valve interface.

– No practical combination with an intermediate throttle plate

possible.

Application examples – If, instead of the operating pressure of the valve manifold, two

additional different pressures are required in ducts 2 and 4.

– When fast venting is required.

– When the pressure regulator for both sides must always be

adjustable.

Tab. 2.10 Reversible AB-pressure regulator

The subsequent example shows the following switching position:

The supply air in duct 1 is passed in the pressure regulator plate to pressure regulators A and B, regu

lated there and then passed to ports 3 and 5 on the valve. In the valve, the supply air is routed to port 2

of the manifold sub-base. The exhaust air is conducted via duct 4 into the pressure regulator plate,

split there to ducts 3 and 5 and exhausted.

3.1 Notes on mounting and dismounting

Warning

Risk of injury to people, damage to the machine and system resulting from uncontrolled

movements of the actuators

� Switch off the operating voltage and the load voltage supplies.

� Switch off the compressed air supply.

� Vent the pneumatics.

Note

Malfunction or damage to the electronics

Electrostatically sensitive devices

� Do not touch contact surfaces.

3.2 Mounting variants

H-rail mounting Wall mounting

The valve manifold is suitable for mounting on an

H-rail (mounting rail in accordance with EN

60715). Follow the safety instructions in the

following chapter. A guide groove on the reverse

side of the valve manifold is used to hold the

H-rail.

The end plates and the manifold sub-bases have

holes for wall mounting. For wall-mounting, Festo

recommends using the holes in every fourth

manifold sub-base in addition to the holes in the

end plates (� Specifications on vibrations and

shock in appendix A, Tab. A.4).

Tab. 3.1 Mounting variants of the manifold assembly

Note

Damage to the valve manifold due to ambient temperature that is too high

� Mount the valve manifold so that there is sufficient space for heat dissipation and

ensure that the maximum limits for temperatures are observed (� Appendix A,

section A.1.2).



3.2.1 Mounting/dismounting on an H-rail

Caution

Risk of injury and material damage due to incorrect mounting

� Make sure that the H-rail can support the weight of the valve manifold and can ab

sorb torsion (e.g. through the vertical stacking).

� When mounting the valve terminal onto an H-rail, note the specifications in standard

EN 60715 and the specifications on vibration and shock in the technical data (� A).

� Perform H-rail mounting only horizontally.

� Mount the H-rail clamping unit.

– Secure the clamping component of the H-rail clamping with the retaining screw

of the H-rail clamping (� Fig. 3.2, number 3).

H-rail mounting without an H-rail clamping unit is not permitted.

For H-rail mounting of the valve manifold, you need the mounting kit VTIA-…-A1 (part

number 533995) for the width 26 mm, and VTIA-…A2 (part number 533996) for the width

18 mm. These mounting kits each consist of 2 M4 screws and 2 clamping components.

3.2.2 Wall mounting and dismounting

The end plates and the manifold sub-bases have holes for wall mounting.

Caution

Risk of injury and material damage due to incorrect mounting

� Mount the valve manifold only on a flat rigid surface.

� In addition to the holes in the end plates, use the holes in every fourth manifold

sub-base.

� Observe the specifications on vibration and shock in appendix A.

� Make sure that the mounting surface can support the weight of the valve manifold

(weights � Appendix A, Tab. A.1).

Mounting

Be sure to leave sufficient space for connecting the supply cables and tubes.

1. Drill mounting holes in the mounting surface.

2. Secure the valve manifold to the mounting surface with screws of sufficient length (� Fig. 3.5).

3.4 Compressed air preparation

Note

Unfiltered or incorrectly lubricated compressed air will reduce the service life of the

valve manifold.

3.4.1 Operation with unlubricated compressed air

Note

Too much residual oil content in the compressed air will reduce the service life of the

valve manifold and result in malfunctions of the valves.

– When using bio-oils (oils that are based on synthetic ester or native ester, e.g. rape

seed oil methyl ester), the maximum residual oil content of 0.1 mg/m³ must not be

exceeded (� ISO 3-8573-1 class 2)

– When using mineral oils (e.g. HLP oils in accordance with DIN 51524 Part 1 to 3) or

corresponding oils based on polyalphaolefin (PAO), the maximum residual oil con

tent of 5 mg/m3 should not be exceeded (� ISO 8573-1-2010 class 4).

Excessive residual oil content is not permissible, independent of the compressor oil, as otherwise the

basic lubrication will be washed out with time.

3.4.2 Operation with lubricated compressed air

Operate the system with unlubricated air, if possible, in order to protect the environment.

Festo pneumatic valves and actuators have been designed so that, if used as intended,

they will not require additional lubrication and will still achieve a long service life.

Note

Operation with lubricated compressed air will cause the life-time lubrication, which is

necessary for unlubricated operation, to be “washed out”.

Observe the following notes if lubricated compressed air must be used.

The quality of compressed air downstream of the compressor must correspond to that of

unlubricated compressed air.

� If possible, do not operate the entire system with lubricated compressed air.

� If possible, always install the lubricators directly upstream of the consuming actuator.



Note

Incorrect supplemental oil and too much oil content in the compressed air will reduce

the service life of the valve manifold and result in malfunctions of the valves.

� Use Festo special oil OFSW-32 or the other oils listed in the Festo catalogue (con

forming to DIN 51524-HLP32, basic viscosity 32 CST at 40 °C).

� Check the correct lubricator setting (� Section)

The additional lubrication must not exceed 25 mg/m3 (ISO 8573-1 class 5).

Adjusting the lubricator

With the machine running (typical operating status) 0.2 to max. 1 drop/min. or 0.5 to 5 drops/1000 l of

air.

The procedure described subsequently can be used to check the lubricator setting.

� Check the service units for condensate and lubricator setting twice a week.

1. Determine the actuator which is furthest from the lubricator.

2. Determine the valve manifold which controls this actuator.

3. Remove the silencer, if present, from port 3/5.

4. Hold a piece of white cardboard at a distance of 10 cm from the exhaust port.

5. Let the system run for some time.

� There must be only a slight yellow colouring on the cardboard. If oil droplets appear, this is an

indication that too much oil has been used.

Another indicator of over-lubrication is the coloration or status of the exhaust air silencer. A distinctly

yellow colouring of the filter element or drops of oil on the silencer indicate that the lubricator setting is

too high.

3.5 General instructions on installation

Warning





� Exhaust the valve manifold pneumatics.

Note

Malfunction or damage to the electronics

Components of the valve manifolds contain electrostatically sensitive components.

� Do not touch any contact surfaces.

� Observe the handling specifications for electrostatically sensitive devices.



3.6 Installation of the tubing lines

If angled connectors or multiple distributors are used, the air flow will usually be reduced.

3.6.1 Connecting

1. Push the tubing as far as possible into or over the tube connection of the fitting.

2. Tighten the clamping screw 1 or, if applicable, pull the locking ring 2 over the tubing connection.

3. Seal unused connections with blanking plugs 3.

4. For a better overview of the system, bundle the installed tubes with a tubing strap or multiple hose

holder.

3.6.2 Removing

Warning

If the pneumatic tubing is under pressure when dismounted, it may perform sudden

unexpected movements, causing injury to persons.

Before disconnecting the pneumatic tubing on the valve manifold:


� Make sure that all pneumatic tubing is unpressurized.

� Exhaust all actuators controlled by valves that are blocked in the neutral or middle

positions.



1. Mark all pneumatic tubing.

2. Loosen the clamping screw 1 of the fitting or, if necessary, press down the locking ring of the fit

ting 2 (e.g. with the loosening tool QSO from Festo).

3. Remove the tubing from the fitting.

Fig. 3.8 Removing the tubing connection

3.7 Pneumatic connection of the valve manifold

Seal working lines (2 or 4) on non-assigned valve positions (valve positions equipped with

blanking plates) with blanking plugs or threaded blanking plugs to protect them from dirt.

In order to guarantee the optimum capacity of the valve manifold, we recommend that more than one

supply or exhaust line be used in the following cases:

– When large volume cylinders are operated at high speeds,

– When several valves (e.g. 10 valves) are switched simultaneously to the flow position.

Valve manifolds equipped with size 18 mm and 26 mm valves can also be supplied via the intermediate

plate.

3.7.1 Ducted exhaust of control air and venting air

In accordance with the standard ISO 15407-1, ports 12 and 14 are intended for supplying the valve

manifold with external pilot air. Festo valves for the valve manifold require pilot air supply via duct 14

only.

In the case of the Festo reversible 2x 3/2-way valves, additional operating pressure is also required at

duct 12 for the internal pneumatic spring. This pressure must correspond to the pilot pressure in duct

14.

If the valve manifold is equipped with valves for ducted pilot and venting air via duct 12, duct 12 must

not be pressurized. Otherwise, the valves cannot reverse.

Therefore, please observe the following points if you wish to use duct 12 for ducted pilot and venting

air:

– The valve manifold is not equipped with reversible 2x 3/2-way valves.

– The valve manifold is not equipped with valves from other manufacturers.

– The seals between the manifold sub-bases and the valves must be mounted in the corresponding

position (� Section 5.4.1).



3.7.2 Pilot control (pilot air supply)

Except for the reversible valves, there are all valve types both for internal and external pilot air. Valves

for external pilot air are identified with the indicator Z in the type code.

Festo recommends using valves with the same pilot control variant (either internal or

external pilot air) on the valve manifold.

Note

If the valve manifold is also equipped with reversible 2x 3/2-way valves (ID code P, Q

and R), pilot air must also be fed via port 12. The pneumatic spring of these valves is

supplied via this port.

Internal pilot air supply

If the operating pressure is within the range of the required pilot pressure (see appendix A, Tab. A.8),

you can use valves for internal pilot air. In these valves, the pilot air is branched from supply duct 1.

External pilot air supply

If the operating pressure is not within the required pilot pressure range for the valves (� Appendix A,

Tab. A.8 and Fig. A.1 … Fig. A.2), you must use valves for external pilot air supply.

Supply the external pilot air via port 14. Under certain conditions (� Section 3.7.1), you can exhaust

the pilot and venting air via port 12.

If you use regulated external pilot air, the valve manifold can be operated safely without

trouble even if the operating pressure fluctuates.

The external pilot air is supplied centrally for all solenoid coils via pilot port 14 on the left

or right end plate. This also applies if the valve manifold is operated with different pres

sure zones (� Fig. 3.9).

� Set the pilot pressure according to the specifications in appendix A, Tab. A.8 or the corresponding

diagrams Fig. A.1 … Fig. A.2.

Note

In a valve position with vertical pressure shut-off plate, duct 14 is blocked by the vertic

al pressure shut-off plate (� Appendix B, Tab. B.10). The valve is supplied with internal

pilot air.



3.7.3 Valve manifold with pressure zone separation

Note

Note the following in the case of valve manifolds which are operated with internal pilot

air and have several pressure zones:

– The pilot air for all solenoid coils is branched centrally from supply connection 1 in

the right end plate.

– The pressure zone which is supplied via port 1 on the right end plate must be oper

ated at a pressure which corresponds at least to the pilot pressure required for the

valve manifold (� Appendix A, corresponding diagrams Fig. A.1 … Fig. A.2).

The pressure zones are formed via isolating discs mounted in ducts 1, 3 and 5. Valve man

ifolds which are equipped solely with valves of the same size can have a maximum of two

pressure zones. Valve manifolds equipped with sizes 18 mm and 26 mm can have a max

imum of three pressure zones.

The following figure shows the assignment of the supply and exhaust ports to the valves using a valve

manifold with blocked ducts 1, 3 and 5 as an example.

The individual pressure zones are supplied as follows (ports 1 or 3 and 5):

– The left outer pressure zone via the left end plate

– The middle pressure zone via the intermediate plate

– The right outer pressure zone via the right end plate.

External pilot air can be supplied for the entire valve manifold via port 14 on the left or right end plate.

6 Supply of pressure zone 1 via the left endplate

Fig. 3.9 Valve manifold with 3 pressure zones and pilot control with external pilot air

3.7.4 Reversibly operated valve manifold

With reversible operation of the valve manifold, the operating pressure is supplied via ports 3 and 5

and the exhaust is vented via port 1.

Note

Operate a reversible valve manifold only with an external pilot air supply.



3.7.5 Operation of the valve manifold with reversible 2x 3/2-way valves

Note

If reversible 2x 3/2-way valves (ID code P, Q and R) are operated together with standard

2x 3/2-way valves (ID code H, K and N) on the valve manifold, the reversible valves must

be operated in a separate pressure zone.

Exception:

If the reversible 2x 3/2-way valves are operated with reversible pressure regulator

plates (ID code ZJ and ZE) (circuit diagrams � Section B, Tab. B.4 and Tab. B.8), a separ

ate pressure zone is not required.

The valve manifold can be operated with reversible 2x 3/2-way valves (ID code P, Q and R) under the

following conditions:

– The pilot exhaust air and venting air must not be exhausted in a common duct.

The reversible 2x 3/2-way valves require compressed air at duct 12 for the pneumatic spring. Duct 12 is

therefore no longer available for removing the ducted pilot air and venting air. Valves which are con

figured for exhausting via duct 12 can then no longer switch (� Section 5.4.1).

3.7.6 Operation of the valve manifold with reversible pressure regulator plates

Note

Operation of the valve manifold with reversible pressure regulator plates (ID code ZM,

ZN, ZJ, ZK, ZL and ZE):

– Reversible pressure regulator plates must not be used on reversibly operated valve

manifolds.

– Standard 2x 3/2-way valves with ID code H, K and N (non-reversible valves) may not

be operated with reversible pressure regulator plates.

– If 2x 3/2-way valves (ID code P, Q and R) are combined with reversible pressure

regulator plates, no separate pressure zone is required. In this combination, pres

sure is supplied via duct 1 and the exhaust is vented via ducts 3 and 5. The pilot

pressure must be supplied via the ducts 12 and 14.

3.7.7 Adjusting the pressure regulator plates

You can adjust the pressure regulator plates in two ways:

– using the adjusting knob

– using the socket head screw in the adjusting knob.



Adjusting the pressure regulator plate with the adjusting knob

1. Pull the adjusting knob 1 out of the locking level 4 into the setting level 2 up to the stop

(� Fig. 3.10).

2. In the setting level, turn the adjusting knob to set the desired controlled variable (� “Flow dia

grams of the pressure regulator plates” in appendix A).

3. Press the adjusting knob into the free-running level 3. In this position you can turn the adjusting

knob without modifying the controlled variable.

4. Turn the adjusting knob in the free-running level longitudinally to the pressure regulator plate.

5. Press the adjusting knob in this position into the snap-in locking of the locking level 4.

3.7.8 Vacuum / low-pressure operation:

Note

Standard 2x 3/2-way valves (ID code H, K and N) are not suitable for use with vacuums

or low pressure in case of supply via port 1.

� Operate these valves in a separate pressure zone.

� The operating pressure for this pressure zone in accordance with Fig. A.1 in ap

pendix A.

The following conditions must be fulfilled so that you can operate the valve manifold at supply port 1

with vacuum or low pressure between –0.9 … 2 bar.

– Only the following valves are used for controlled external pilot air supply:

– Monostable 5/2-way valves (identifier M52-AZ / M52-MZ)

– 5/2-way bistable valves (identifier B52-Z / D52-Z)

– 5/3-way mid-position valves (identifier P53C-Z / P53E-Z / P53U-Z)

– Reversible 2x 3/2-way valves (identifier T32F-AZ / T32N-AZ / T32W-AZ). These valves must be

operated via ports 3 and 5 in a separate pressure zone with vacuum or low pressure.

3.7.9 Connecting the pneumatic lines

Note

� Use blanking plugs to seal all ports not required for the functioning of the valve man

ifold.



1. Mount the fitting or the silencers in accordance with the following table (� Tab. 3.2). The position

of the pneumatic ports is shown in Fig. 3.12.

4.1 Prior to commissioning

� Switch off voltage before plugging together or disconnecting plug connectors (damage to function

ing).

� Only commission a valve manifold that has been mounted and wired completely.

� Make sure that there is a sufficient supply of fresh air (cooling) for the following operating condi

tions:

– Maximum number of valves

– Maximum operating voltage

– When the solenoid coils are constantly under stress.

� Observe the following notes on building up pressure in the overall supply.

4.2 Pressure build-up in the overall supply

Warning

Risk of injury to people, damage to the machine and system resulting from sudden


If the build-up of pilot air is too slow or delayed, this may lead to sudden unexpected

movements of the actuators under the following conditions:

– When the compressed air is connected via a safety start-up valve (gradual pressure

build-up) and

– If there are electric signals (e.g. after EMERGENCY OFF switching).

� Operate the valve manifold with external pilot air with the pressure listed in ap

pendix A, Fig. A.1 … Fig. A.2.

� Branch off the pilot air in front of the safety start-up valve (� Fig. 4.1).

4 Commissioning


The pilot air must be applied immediately after it is switched on at the minimum pressure specified in

appendix A, Fig. A.1 … Fig. A.2 for the corresponding valves. Otherwise there is no guarantee that the

valve will reverse directly (� Fig. 4.1).

If the pressure is less than the minimum specified, there may be a delay before the valve is switched, in

spite of an electric signal being present. The gradual pressure build-up of the overall supply does not

affect the actuator in that case. The actuator would react suddenly (e.g. a cylinder would extend or

retract suddenly, depending on the valve function).

4.3 Manual override (MO)

The manual override enables the valve to be switched in a not electrically activated, de-energised

status. Only the compressed air supply needs to be switched on. You should use the manual override

mainly when commissioning the pneumatic system in order to check the function and operation of the

valve or the valve-actuator combination. The valve is activated by pressing the manual override.

Depending on the manual override variant, there are the following actuation types:

Actuation type Mode of operation

Non-detenting After actuation, the manual override is reset

automatically by spring force.

Before actuating the MO:

Warning



� Disconnect the operating voltage supply to prevent accidental actuation of the

solenoid coils.

Note

A valve that has been switched by an electric signal cannot be reset by the manual over

ride. The electric signal is dominant in this case.

� Before actuating the manual override, reset the electric signal.

Before testing the valve-actuator combination:

Warning

Risk of injury due to uncontrolled movements of the actuators

� Make sure that nobody is in the danger zone.

Testing the valve-actuator combination:

1. Switch on the compressed air supply

Note

Incorrect actuation of the non-detenting manual override can lead to malfunctioning or

damage to the manual override

� Use a screwdriver (blade width max. 4 mm) to actuate the manual override.

� Actuate the manual override with a maximum of 25 N.

2. Test the functioning and effect of each valve-actuator combination by actuating the corresponding

manual override (� Tab. 4.4 and Tab. 4.5 ).

� Exhaust the valve manifold pneumatics.

Note

Handle all modules and components of the valve manifold with great care. Note espe

cially the following when mounting components:

� Screws inserted exactly (prevents damage to threads).

� Screws must be turned by hand only and inserted so that the self-cutting threads

can be used.

� Comply with the specified torques.

� Threaded fittings must be free of distortion and mechanical tension.

� Check seals for damage (to maintain IP degree of protection).

� The contact surfaces must be dry and clean (sealing effect, avoidance of leakage

and contact errors).

5.3 Replacing valve manifold components

Components on the manifold sub-bases of the valve manifold can easily be replaced for maintenance

and conversion work.

5.3.1 Replacing valves or cover plates

Dismounting

� Loosen the mounting screws and remove the component from the manifold sub-base (� Fig. 5.1).

Fig. 5.1 Removing valves or cover plates

Mounting

1. Check seals for damage and replace damaged seals.

2. Make sure that the seals between the manifold sub-base and component are in the correct position.

– For blanking plates, the seal must be in the recess of the blanking plate.

– With valves, the seal must sit in the recess in accordance with the exhaust variant

(� Section 5.4.1).

3. Place component onto the manifold sub-base.

4. Screw the component on at first only slightly and then tighten with the following tightening torque:

– Valves of width 18 mm: 1.0 Nm ±10 %

– Valves of width 26 mm: 2.0 Nm ±10 %



5.3.2 Replacing/adding vertical stacking components

The valve manifold can be equipped with the following vertical stacking components:

– Pressure regulator plate

– Flow control plate

– Vertical pressure shut-off plate

– Vertical pressure supply plate

Note

No valve function

� Do not combine a standard 2x 3/2-way valve (identifier T32C-A / T32H-A / T32U-A)

with reversible pressure regulator plates (identifier R5-..., R6-..., R7-...).

If this combination is used, the pneumatic spring of the valves does not function. The

valves cannot return from the switching position to the neutral position.

Vertical stacking with pressure regulator plate:

� Always mount the pressure regulator plate as the highest component of the vertical

stacking.

� This guarantees free access to adjusting screws or connections (� Tab. 5.3).



The following component sequence is recommended for valve positions with vertical stacking:

Fig. 5.2 Recommended sequence of valve position components



Note

– Reversible pressure regulator plates should only be combined with valves that can

be operated in reverse mode.

– Valve position with vertical pressure shut-off plate:

The pilot air supply for the valve is branched internally from duct 1 in the vertical

pressure shut-off plate, even if the valve manifold is operated with external pilot air

(� Appendix B, section B.1). If the valve manifold is equipped with vertical pressure

shut-off plates at all valve positions, supplying the valve manifold with external pilot

air is not required. In this case, the operating pressure at which the valve manifold is

operated must be within the range of the required pilot pressure (� Appendix A,

Fig. A.1 … Fig. A.2).

– The combination of reversibly operated valve manifolds with the following vertical

stacking components is not permitted:

– Reversible pressure regulator plates

– Flow control plates

– Vertical pressure shut-off plates

– Vertical pressure supply plates

Removing the components

1. Unscrew mounting screws of all components above the relevant position.

2. Remove these components from the valve position.

Mounting new components

1. Check seals for damage. Replace damaged seals.

2. When mounting the valve:

Insert seal between the valve and the vertical stacking component according to the desired exhaust

variant (� Section 5.4.1).

3. Place the new component on the valve position, possibly onto a component already mounted.
