PRESSURE RELIEF VALVES

4

FEATURES x The movable parts of these seat type valves do represent an optimized FORCE-

MASS-SPRING DESIGN. Together with the typical DENISON pilot stages the

pressure overtravel of the DENISON two stage pressure relief valves is limited to

around 10% of the setting pressure.x Due to the DENISON push-pin design the pilot cracking flow is reduced to a

minimum.x The DENISON design of pressure relief valves enables an extraordinary low

pressure increase versus flow.x Pressure relief valves are available in a broad range of configurations for various

market segments.DENISON internal standard parts ensure a good performance

repeatability over the whole range.

PRESSURE DIFFERENTIAL In applications with an accumulator, it should be noted that the unloading valve

and its accompanying check valve should be mounted as close to the accumu-

lator as possible.

This will prevent that the „ p, caused by long feed lines between the unloading

valve and the accumulator, will reduce the selected 15 or 28% pressure differen-

tial (prevention of switching oscillations).

FEATURES x The design combines a poppet type seat valve with an optimized pilot control,

which offers a precise pressure adjustment and quick opening response.

Pressure variations and system shocks are reduced to a minimum using this

design, dependent upon system design.x When the valve is fully open, a minimum pressure drop through the valve offers

the advantage of low energy lost in each system.x For sensitive pressure settings three setting ranges are available;

. . . 105, 210, 350 bar.x Three sizes with nominal flows 60/200/450 l/min are available (max 600 l/min).x An integrally mounted solenoid vent valve (sandwich type VV01) is available for

each pressure valve.

REDUCING VALVES

11

FEATURES x This pilot operated seat valve design delivers a quick response and extremely

stable secondary pressure.x The main stage poppet is guided by a ball-bearing and enables a minimum

friction between poppet and sleeve and a superior hysteresis.x The pilot stage is provided with a mini-flow control valve which controls the main

stage independent from primary pressure variations.x The poppet of the main stage is “normally“ closed. When the setting pressure is

reached only enough flow is passed from B to A to maintain secondary pressure.

This design eliminates pressure overshoots at the secondary system.x A small check valve in the main poppet prevents the secondary system from

exceeding the pilot setting (max. flow 5 l/min).

or the valve is not sufficient for the investigated conditions.

E.g. there are no functional limits given for the BOSCH NG25 valve in the sales catalogue. The only information

is that the maximum flow is 700 l/min, which is normally not accurate for all type of spools.

Capability Level Diagram CETOP 3, 5, 7, 8 [%]

All values are taken from manufaturers latest sales catalogues (Standard components, 24 V DC, ⁄ = 36 . . . 41 cSt).

In order to summarize information on the previous page the following diagram given an overview of the

manufacturers features.

This diagram proves, that DENISON directional valves CETOP 3, 5, 7 and 8 are among the best

components available on the world market.

REMARKS:

The capability value C is the summary of the three main characteristics:

x p max Maximum pressure (taken from the functional limits diagrams).

x Ql Average of maximum flow at functional limit of the three spools.

x „ pl Average of pressure drop through the whole valve (PfA + BfT) of the three spools.

Obviously these values can not characterize the valves for each demand. Each application requires to be considered

individually for max. flows, pressure and acceptable pressure drops.

FLOW CALCULATION Flow at other pressure drops than “Nominal Pressure Drop“:

Example: 4DP01 E 243 F30

Spool type F30 means 30 l/min at 5 bar „p for each metering edge, or flow of

30 l/min at 10 bar „p across two metering edges, e.g. P–A–B–T.

Proportional Directional Valve 4DP01 with Feedback

Nominalflowl/min

Command signal

PRESSURE COMPENSATOR

APPLICATION

At different pressure drop across a valve (ports P–A–B–T) the flow fluctuates

e.g. from 17.5 . . . 36 l/min. This can bemeasured as shown in the diagram above or

calculated by use of the following form:

QX =QNöä„pX„pN

QX = Flow at different pressure drop pXQN = Nominal flow e.g. spool F10 = 10 l/min

„pX = Actual pressure drop

„pN = Nominal pressure drop 10 bar „p (P–A–B–T)

= 5 bar (P–A) + 5 bar (B–T)

Example: – Command signal 80%

– „pN = 2 x 5 = 10 bar

– QN = 17.5 l/min (see above)

– „pX = 2 x 20 = 40 bar

– QX = ?

QX = 17.5 l/minöä40 = 35 ≈ 36 l/min10

The flow over the spool edges is not pressure compensated. That means, variati-

ons in pressure either on the pump or the actuator side will have direct influence

on the flow rate through the valve (as underlined in the diagram).

NOTE: FOR CONSTANT PRESSURE DROP ACROSS PROPORTIONAL

VALVES A PRESSURE COMPENSATOR SHOULD BE INSTALLED

(SEE PAGE 27).

PRESSURE COMPENSATORS FOR PROPORTIONAL DIRECTIONAL VALVES

27

FEATURES x Constant flow regulation by proportional directional valves in combination with

pressure compensators.x Precise repeatability of flow independent of load or system pressure.x Available as 2-port and 3-port compensator.x Pressure drop optional: constant 5 or 10 bar; adjustable up to 5 bar.x Internal shuttle valve transmits load pressure feedback from either A or B port.

Flow = f (A, „p)

With a compensator the pressure drop („p) over one valve spool edge is regulated

to constant value. At one specific opening area (A) and constant pressure drop

(„p const.) the flow across the proportional valve is constant, independent of

operating pressure and load pressure (cylinder, motor).

COUNTERBALANCE VALVES (STACKABLE)

29

FEATURES x In systems where load changes from positive to negative, a counterbalance valve

should be used to limit the velocity of the actuator by the flow supplied by the

system.x The opening of the counterbalance valve is controlled by pilot pressure coming

from the control side of the actuator.

The pilot ratio of DENISON valves series ZNS is:

Pilot ratio =Load induced pressure (pi)

=4.5

Pilot pressure (pp) 1

x DENISON counterbalance valves are available as stackable valves in accor-

dance to CETOP 3 and CETOP 5 subplate configurations.

As standard they are provided with reserve flow check valve(s).

COMPRESSIBILITY OF OIL VOLUME

52

Though hydraulic oil is often regarded as an ideal, incompressible fluid, in certain applications (e.g. hydraulic presses)

the compressibility has to be taken into consideration. An increase of the operating pressure „p of an original volume V0

under starting pressure p0 will cause a decrease „Voil of the volume.

„Voil = A · „I = V0 ·„p

Eoil

The module of compression Eoil is depending on temperature and pressure, but can be regarded as a constant value for

the usual conditions of hydraulic systems. An useful average value is:

Eoil ≈ 1.6 · 109N

= 1.6 · 104 barm2

Example:

A cylinder with the dimensions 300/220 mm and a stroke of 150 mm is compressed with a pressure of 300 bar

(which can be regarded as differential pressure „p, because the tank pressure can normally be ignored).

VCYL = I ·™· d2 = 10.6 Liter

4

The oil volume in the piping between cylinder and control valve (or pilot operated check valve) has to be taken into

consideration as well. A pipe 38 x 5 mm with a length of 2.5 m has a volume of:

VPIPE = I ·™· (D2 – d2) = 3.1 Liter

4

The original volume V0 is the sum of both:

V0 = VCYL + VPIPE = 13.7 Liter

The decrease of the Volume „Voil is called compression volume:

„VOIL = 13.7 Liter ·300 bar

= 0.26 Liter1.6 · 104 bar

WHEN DECOMPRESSION-SHOCKS TO BE EXPECTED

53

The following diagram is an useful tool to evaluate at which combinations of the volume of the compressed oil and the

operating pressure decompression shocks can be expected.

shocks to be expected

shocks not to be expected

Volume (Liter)

Pressure

(bar)

Limit-curve for decompression shocks.

Oil pressure versus compressed volume.

The compressed volume consists of the oil in the cylinder and in the piping to the control valve. If the diagram indicates,

that decompression shocks have to expected, there are various possibilities how to alter the hydraulic configuration to

avoid them. Two are figured out in the following examples:

Examples: Different concepts to control the decompression time

On the previous page an example of

a differential cylinder and it’s piping

was given:

The oil volume V0 = 13.7 Liter and the

operating pressure „p = 300 bar can

be applied to the diagram:

diagram predicts

decompression shocks!

The solutions consist of the use of

an additional decompression

component, that allows a limited

flow in a separate decompression

operation in the machine cycle.

With Needle Valve With Proportional Pressure

Relief Valve R4V03 . . . P2

Common experience values:

– A decompression volume of „V = 1000 cm3 (1 Liter, 0.26 U.S. gallon) requires a decompression time of

approximately „t = 1 second.

– As a value often used, but based on pressure: Decompression rate 300 . . . 1250 bar per second:

300 bar/s; for ”hard” systems, machines with gray iron casting frames, more steel piping, smaller entrapped

volume, smaller cylinders . . .

1250 bar/s, for more ”flexible” systems, machines with welded steel frames, more flexible hoses, larger entrapped

volume, larger cylinders . . .
