Deluge valve sets


1.1. General

Deluge valve sets are used in water spray extinguishing systems with open downstream pipework.They are always to be used when large areas are to be extinguished with water through acorrespondingly large number of nozzles. Typical fields of application are:

• Cooling of tank installations• Fire protection for transformer stations• Fire protection for platforms• Fire protection for process plants, etc.

Depending on the application the deluge valve sets are fitted with different actuators.

The following actuating variants are approved by the German Damage Insurers Association(VdS):

− Electric actuation via impulse solenoid valve 24 V/DC. Special designs with 12V impulse solenoidvalve available upon request. A detection system is usually necessary to trip the solenoid valve. Thisdeluge valve set returns to closed operating position by resetting the impulse solenoid valve (remotecontrol possible).

− Electric actuation via a normal 2/2-way solenoid valve 24 V/DC. Special designs with 12V 2/2-waysolenoid valve available upon request. A detection system is also usually necessary to trip thesolenoid valve. Resetting of this deluge valve set to operating mode is only possible at site byoperating the quick drain valve (remote control not possible).

Caution: Please use impulse actuation 24 V/DC in case of a new installation with electric actuation. Wewill phase out the electric actuation with normal 2/2-way solenoid valve 24 V/DC incombination with the quick drain valve.

− Pneumatic release via diaphragm valveA diaphragm valve is actuated by pressure drop in a pilot pipework actuated by heat sensors.

− Hydraulic actuation working directly on the control chamber of the deluge valve.Actuation via pilot pipework by pressure drop from sprinklers.In the case of hydraulic actuation the geodetic height difference between the pilot pipework and thedeluge valve set, depending on the water supply, is a factor that must be taken into account.

Deluge Valve Sets


3. Mode of functioning

How electric, pneumatic and hydraulic actuation works is explained in the following description with theaid of illustrations and diagrams (Fig. 1 - 8).

In addition to the automatic actuation systems (electric, pneumatic or hydraulic) each of these variants isalso fitted with a manual actuation mechanism. When the manual actuation valve (5) is opened thecontrol chamber of the deluge valve is depressurised and the deluge valve is actuated by water pressureon the valve head.Minimum water supply pressure is 3 bar for all variants of nominal diameter DN 50 -150.

3.1 Electric actuation (Fig. 1 and 2 or 3 and 4)

Electric actuation of the deluge valve set is normally by means of a detection system, which actuates thesolenoid valve (4) in the event of fire. The solenoid valve (4) opens, causing pressure in the controlchamber of the deluge valve (1) to fall and the valve head to be actuated by water supply pressure. Thedownstream pipework is flooded with water and the alarm gong and the alarm pressure switch (alarm to acontinuously manned post, e.g. fire brigade, porter, etc.) are activated.

According to the VdS regulation the deluge valve must also remain in open position in case of a powerfailure, e.g. caused by fire. This requirement is met with the following activation technologies:

• actuation with impulse solenoid valve• actuation with normal 2/2-way solenoid valve and additional quick drain valve

3.1.1 Electric actuation with impulse solenoid valve (Fig. 1 and 2)

With this actuating technology the once actuated solenoid valve also remains in open position in case ofa power failure. The solenoid valve and thus also the deluge valve are closed again only by reversing(current pulse to the reset coil).

The activation coil must be de-energised (also the monitoring voltage must be switched off) for resettingthe pulse valve because otherwise the solenoid valve will not close. These special features are includedin Minimax activation technology.

3.1.2 Electric actuation with 2/2-way solenoid valve (Fig. 3 and 4)

A quick drain valve (6) is arranged in parallel to the 2/2-way solenoid valve (4) so that the deluge valveremains in open position after actuation and does not close again in case of a voltage drop, open circuit,etc. This spring-loaded valve opens if the pressure drops below 1.4 bar and keeps the control chamber inthe deluge valve free from pressure. The deluge valve can only be closed again by closing the quickdrain valve (6) on the deluge valve set itself (cf. function of the quick drain valve in Section 4.3).

3.2 Pneumatic actuation (Fig. 5 and 6)

Pneumatic actuation of the deluge valve sets is effected by means of a pilot pipework filled withcompressed air. This is a pipework of nominal diameter ≥ DN 8 fitted with special heat sensors (solderedlink). The pilot pipework keeps the diaphragm valve (4) and accordingly the deluge valve (1) closed. Anautomatic compressed air supply (20-26) maintains the control pressure of approx. 2-3 bar.

When one or more of the heat sensors responds, pressure in the pilot pipework and accordingly also inthe diaphragm chamber of the diaphragm valve (4) falls. If control pressure in the pilot pipework is below1/6 of the water supply pressure the diaphragm valve (4) opens and depressurises the control chamberof the deluge valve (1). The deluge valve opens, the downstream pipework is flooded with water and thealarm gong and the alarm pressure switch (alarm to a continuously manned post, e.g. fire brigade, porter,etc.) are activated.

The diaphragm valve (4) and accordingly also the deluge valve (1) remain open because there is nopossibility of pressure building up again in the pilot pipework after a heat sensor has responded even ifcompressed air is automatically replenished (throttle). For this reason there is no need to install a quickdrain valve in a pneumatic actuation system.

In order to avoid nuisance actuation the pneumatic pilot pipework must be kept at operating pressure bymeans of automatic compressed air replenishment. Depending on the size of the pilot pipework therecommended operating pressure is between 2 and 3 bar. In order to keep actuation time short evenwhen the pilot pipework is a large one, operating pressure ought to be kept on the low side at around 2bar.

The compressed air supply connection is a prefabricated assembly consisting of the components item 20to 26:

3.3 Hydraulic actuation (Fig. 7 and 8)Unlike electric and pneumatic actuation, hydraulic actuation has the pilot pipework acting directly on thecontrol chamber of the deluge valve (1). The pilot pipework is constantly supplied with water through theequaliser boring (throttle non-return valve) in the piston rod of the deluge valve.

The actuate elements are sprinklers which, on responding to an outbreak of fire, depressurise the pilotpipework and accordingly the control chamber of the deluge valve. In the interests of assuring anadequate margin of safety for release of a deluge valve connected to a hydraulic pilot pipework, themaximum geodetic height difference between the control chamber of the deluge valve and the highesttrigger sprinkler is limited in relation to water supply pressure. In addition to this, pressure losses at a flowrate “X“ over the distance to the most remote trigger sprinkler must be taken into account.

The maximum permissible geodetic height for the pilot pipework is calculated with the aid of the followingformula:

pKges.

p= H ∆−

H = Max. permissible geodetic height for the hydraulic pilot pipework [m]p = Pressure in the water supply system [m WH]Ktot. = Safety and gearing factor for deluge valve actuation [4]∆p = Pressure loss in accordance with “Hazen/Williams“[m WH]m WH = Water head in metresX = Flow rate via throttle return valve in the deluge valve with a Kv of 8 l/min.

Example:Given a water supply pressure of 9 bar and a calculated pressure loss in the pilot pipework of 2.5 m WH,permitted height ”H” will be as follows:

m 205,24

90=p4p=H =−∆−

The height difference in the pilot pipework between the deluge valve and the highest sprinkler may be upto 20 m.

A quick drain valve (6) is fitted on the control chamber of the deluge valve in order to shorten the delaybefore release of the deluge valve in hydraulically actuated systems. When pressure in the pilot pipeworkfalls below the actuation pressure of the quick drain valve, this valve opens and accelerates the fall inpressure in the hydraulic pilot pipework, which, in turn, cuts down the time required for the deluge valve tobe released.

The actuating pressure of the quick drain valve depends on the pressure of the water supply and will beapprox. 50% of the lowest water supply pressure, as given in column 1 of the table below. The quickdrain valve is factory set and marked accordingly. Four quick drain valves set at the following pressurescan be supplied to match various water supply systems:

Water supply Actuating pressure Order no.≥ 3 to 5 bar 1.4 bar 84 1768> 5 to 7.5 bar 2.3 bar 84 1770> 7.5 to 10 bar 3.4 bar 86 1909> 10 to 12.5 bar 4.5 bar 86 1910

4. Function of the major components

4.1 Deluge valve (Fig. 9)

The deluge valve is a piston controlled shutoff valve, which establishes a seal at twice the pressure of thewater supply system (see Fig. 9). The valve head is connected rigidly to the system by a piston rod. Apressure equaliser boring in the piston rod balances water supply pressure and pressure in the valvecontrol chamber. A non-return ball valve in the equaliser boring prevents a fall in pressure in the controlchamber even if pressure in the water supply system drops. As the surface area of the piston is greaterthan that of the valve head, a reliable seal (double pressure) is established against the water supply. Thisseal is reinforced by a spring which keeps the valve head closed even when the valve is depressurised.

The cavity between the piston and valve head is connected to the downstream pipework at the valveoutlet. The downstream pipework is, as a rule, at atmospheric pressure and is flooded when the delugevalve is released. The valve is released by falling pressure in the control chamber brought about bysuitable actuate elements, e.g. solenoid valve, diaphragm valve or direct connection to a hydraulic pilotpipework. It must be ensured that water is drained from the control chamber by the actuate elementsfaster than it can be replenished through the equaliser boring (non-return ball valve) so that there is norenewed pressure build-up in the control chamber.

Figure 9: Deluge valve

Deluge valve sets


4.2 Solenoid valves (Figure 10 and 11)

The solenoid valve for electric actuation is a 2/2-way valve with an operating voltage of 24 V-DC, which isactuated by a detection system. In its READY state the solenoid valve is not actuated, i.e. it is normallyclosed (NC) and thus, establishes a seal against the control chamber of the deluge valve.

In case of an actuation of the solenoid valve it must be ensured that the deluge valve remains in openposition even if a power failure, open circuit, etc. occurs. This is guaranteed by using the followingactuating technologies:

Actuation with pulse valve which remains in open position after activation and only closes when beingreversed (current pulse to the reset coil).

Actuation with a normal solenoid valve in connection with a quick drain valve. In this case thesolenoid valve switches back to closed position in case of a voltage drop. The quick drain valveswitched in parallel remains in open position (cf. function of the quick drain valve in 4.3).

4.2.1 Impulse solenoid valve (Fig. 10)

The impulse solenoid valve is in closed position when being activated at terminal 1 with phase (+). In thisswitching position the applied water pressure acts on the top of the diaphragm (3), which seals the valveseat. Owing to the difference in surface area (total area at the top compared to the smaller ring area atthe bottom), the diaphragm establishes a secure seal on the valve seat. The conical spring (4) keeps thediaphragm on the valve seat closed even when the valve is depressurised. The reversal of the solenoidvalve (phase (+) to terminal 2) causes a pressure drop in the diaphragm chamber and thus, thediaphragm (3) is lifted from the valve seat. A minimum pressure of 0.2 bar must always be available aspressure difference.

The reversal is carried out via a clapper-type armature (10), which is moved to the correspondingoperating state by the solenoid coils (13) and thus, closes or opens the throttle/relief boring. Thisfacilitates the following switching states:

a) valve closed throttle boring (x) open relief boring (y) closed by clapper-type armature pressure medium applied to diaphragm chamber

b) valve open throttle boring (x) closed by clapper-type armature relief boring (y) open diaphragm chamber is depressurised

4.2.2 2/2-way solenoid valve (Fig. 11)

In its READY state the solenoid valve is not actuated, i.e. it is normally closed. In this position thepressure medium acts on the top of the membrane (3) through the 0.8 mm diameter throttle boring(throttle item 4). Owing to the difference in surface area (total area at the top compared to the smaller ringarea at the bottom), the diaphragm establishes a secure seal on the valve seat. When the solenoid valveis actuated by activating the solenoid coil (10) the valve armature (8) uncovers the 1.8 mm diameter reliefboring, depressurising the upper diaphragm chamber. The diaphragm lifts off the valve seat and thesolenoid valve switches to continuity.

4.3 Quick drain valve (Fig. 12)

The quick drain valve has a spring loaded valve head (4) which is opened by falling pressure andremains open even when pressure subsequently rises. The valve head (4) can only be closed again bypressing the spherical button (11) and will remain in the closed position as long as sufficient pressure ismaintained - between 1.4 and 4.5 bar, depending on the setting of the spring (marked on the housing).With the drain valve in its READY, i.e. closed, position the piston rod (8) and spherical button (11) can bemoved freely. Because the piston or guide rod is jointed pulling or pushing the spherical button will haveno effect and cannot result in advertent release of the deluge valve. This valve is used in electricallyactuated deluge valve sets with normal 2/2-way solenoid valve (no pulse valve) and hydraulic pilotpipework. When the solenoid valve is electrically actuated the control chamber of the deluge valve is keptdepressurised by the quick drain valve even when the solenoid valve closes again.

In systems fitted with a hydraulic pilot pipework the quick drain valve speeds up emptying of the controlchamber or pilot pipe and accelerates release of the deluge valve accordingly. To suit variousapplications, quick drain valves with the following spring settings are available:

For electric actuation: 1.4 bar

For hydraulic actuation: 1.4 bar2.3 bar Different actuation pressures depending on water3.4 bar supply pressure, see also hydraulic actuation in 3.34.5 bar

4.4 Diaphragm valve (Fig. 13)

In its READY position the diaphragm valve for pneumatic actuation is kept closed against the waterpressure in the deluge valve control chamber by the pneumatic pilot pipework. An automatic supply ofcompressed air keeps pressure in the pilot pipework at between 2 and 3 bar. When a heat sensorresponds pressure in the pilot pipework and diaphragm chamber of the diaphragm valve falls.

When the pressure in the diaphragm chamber falls below the actuating point (approx. 1/6 of water supplypressure) the diaphragm valve opens and depressurises the control chamber of the deluge valve. Thedeluge valve opens and allows water to flow into the downstream pipework.

5. Deluge valve sets maintenance regulations

In addition to the usual tests laid down in the operating regulations, regular maintenance of functionalparts is essential to the operating safety and reliability of deluge valve sets. Maintenance intervals shouldbe no longer than annually and a function check of the following essential instruments:

Deluge valve

Solenoid valve

Quick drain valve

Diaphragm valve (only in pneumatically actuated systems)

should be carried out in the event of the system being genuinely actuated (e.g. tripping by a detectorsystem).

Maintenance is to be carried out in the following sequence:

1. Function test on the deluge valve set comprising

Tripping by detectors in the case of electrically actuated systems

Test valve in the case of pneumatically and hydraulically actuated systems

The outlet gate valve on the deluge valve set is to be closed in order to prevent flooding of thedownstream pipework.

2. Maintenance of the release valves in accordance with the following maintenance regulations5.1 Deluge valve (DN 50 – 150)

5.2 Solenoid valve 2/2-way-NC5.2.1 Impulse solenoid valve5.2.2 2/2-way solenoid valve

5.3 Quick drain valve

5.4 Diaphragm valve (only in pneumatically actuated systems)

3. Return to service in accordance with operating regulations

4. Final function test as per 1. above and return to service in accordance with operatingregulations.

Deluge Valve Sets


5.1 Deluge valve maintenance regulations (Fig. 14)

As a basic rule before any maintenance of the deluge valve is carried out, the deluge valve set must beactuated using the appropriate actuation system, e.g. detector system, and checked for properfunctioning. The outlet gate valve must be closed first in order to avoid flooding the downstreampipework. See also operating regulations for deluge valve sets.

The following maintenance sequence is then to be observed:

Close the inlet and outlet gate valves of the deluge valve set.

Drain the deluge valve (set the 3/2-way valve to the test position and open the drain valve of thedeluge valve set).

Unscrew the inspection cover (13).

Unscrew the cover of control chamber (12)

Caution: Owing to the powerful springs (10) under the cover of control chamber (12)the nuts on the cover must be loosened carefully and evenly in order to avoid injury.

Remove the complete piston (7) by twisting slightly and lifting upwards.

Clean the inside of the valve and lubricate the piston sleeve (17).

Check the O-ring (4) in the piston sleeve (17) for damage and replace if necessary.

Check the valve head gasket (3) for damage and replace if necessary.

5.2 Solenoid valve maintenance regulations (Fig. 15)

Before any maintenance is carried out the solenoid valve must be tripped by means of the detectorsystem or test detector and checked for proper functioning (cf. maintenance regulations for deluge valveset, Section 5 and 5.1).

The solenoid valve, which actuates the deluge valve set is an extremely important component. It isaccordingly essential to check on this valve when routine annual maintenance is carried out and tomaintain this valve as described in Section 5.2.1 and 5.2.2.

Especially the control component of the impulse solenoid valve is different from the conventional 2/2-waysolenoid valve. Therefore different regulations must be observed when maintaining the valve.

5.2.1 Impulse solenoid valve maintenance regulations

The control component (coil set) of this valve is completely sealed from the applied pressure media with aformed gasket (15). Thus, the armature room cannot become dirty so that the control component mustnot be maintained. This also applies to the set screws (11) with throttle and relief boring. These setscrews (11) are factory adjusted and secured with screw safety paint.

Caution: Loosening the two fastening screws (9) of the coil or changing the adjustment of the two setscrews (11) (secured with red safety paint) causes malfunctions.

If required, the complete control component (coil set) must be exchanged (see spare part list). Thus,maintenance of the impulse solenoid valve is limited to checking the diaphragm chamber and must becarried out as follows:

Switch off the power supply to the solenoid valve (detector system) and unscrew or pull off the plughead (8) if necessary.

Loosen the 2 diagonally arranged fastening screws (7) (without safety paint) and remove thecomplete coil set (9 - 16).

Caution: The 3 O-rings 6 x 1.5 (14) for sealing the connection channels are just inserted loosely andmay get lost. Loosening or adjusting the secured screws (9) or (11) (red safety paint) is notpermissible.

Loosen the 4 fastening screws (6) (not included in the drawing) at the valve housing (1) and removethe valve cover (2).

Caution: The 2 O-rings 4 x 1.5 (5) for sealing the connection channels and the conical spring (4) arejust inserted loosely and may get lost.

Clean valve housing (1) and cover (2).

Clean diaphragm (3), conical spring (4) and O-ring (5), check for damage and replace if necessary(for wearing parts set see spare part list)

Insert diaphragm (3), conical spring (4) and O-ring (5) in the valve cover (2) and reattach to thehousing (1):

Caution: The correct position of the components is extremely import for operating the valve. A missingO-ring causes a malfunction of the solenoid valve.

Screw in coil set (9 - 16) and plug head (8).

Caution: Please observe position of the coil set (9 – 16) to the flow direction of the valve (see arrow).A wrongly assembled coil set (180° turned) reverses the function of the solenoid valve!

Reconnect the solenoid valve to the power supply.

Important: Final functional test of the solenoid valve is carried out with the detector system or testdetector

5.2.2 2/2-way solenoid valve maintenance regulations (Fig. 16)

The control component of this solenoid valve is a valve armature, which closes the relief boring beingapplied with the pressure media and supported by a pressure spring. Thus, the armature room ispermanently in contact with water so that it may pollute easily. Therefore it is absolutely necessary toinclude not only the diaphragm chamber but also the armature room in the annual maintenance work.

The maintenance work must be carried out as follows:

Switch off the power supply to the solenoid valve (detector system)

Loosen the retaining nut (11) with an AF 14 spanner and withdraw the solenoid from the tubus (7)

Loosen the tubus (7) with an AF 22 spanner and unscrew it from the valve cover (2). Clean the tubus(7), armature (8) and pressure spring (9), check them for damage and if necessary replace.

Caution: The tubus, armature and spring (7, 8, 9) must be replaced all together. Screw the completetubus assembly back in and make finger tight (metal seal).

Unscrew the valve cover (2) with an AF 4 socket wrench.

Remove the diaphragm (3), clean it, check for damage and if necessary replace.

Clean throttle with sieve and O-ring (4, 5, 6), check for damage and if necessary replace.

Caution: The sieve must be absolutely clean. If there are any deposits of limescale the sieve must bereplaced.

Replace the diaphragm and throttle complete with O-ring in the valve housing and screw on the valvecover.

Caution: It is extremely important that the diaphragm and throttle be correctly positioned. A missingthrottle or O-ring causes a malfunction of the solenoid valve.

Replace the coil and screw tight

Switch on power supply to the solenoid valve again.

Important: Final functional test of the solenoid valve carried out by the detector system or test detector

5.3 Quick drain valve maintenance regulations (Fig. 17)

The quick drain valve opens when pressure falls below the set value (marked on the valve) and keepsthe control chamber of the deluge valve depressurised even if the solenoid valve closes again.

Note: Electrically actuated deluge valve sets (only in case of the conventional 2/2-way solenoid valve in4.2.2) must only be fitted with quick drain valves whose set response pressure is 1.4 bar.

As a basic rule (depending on water supply), quick drain valves with higher response pressures are onlypermissible in hydraulically actuated systems.

Maintenance is essentially confined to function testing, the set response pressure, e.g. 1.4 bar, beingtested by reducing pressure in the control chamber of the deluge valve (vent valve). The following testsequence is to be observed:


Reduce pressure in the control chamber of the deluge valve by opening the vent valve on thepressure gauge shutoff valve in the cover of the control chamber.

Check the response pressure at the pressure gauge; to be noticed by an immediate pressure drop tobelow 1.4 bar and simultaneous discharge of water from quick drain valve.

Restore the valve to service by opening the inlet gate valve and at the same time pressing thespherical button on the quick drain valve (cf. start-up in the operating regulations under III).

If the quick drain valve is found to be leaky the following maintenance must be carried out:


Use the drain valve to depressurise the control chamber of the deluge valve.

Caution: It is advisable to remove the quick drain valve from the deluge valve entirely and to clamp itin a suitable vice for maintenance.

Unscrew the locking screw (7) and remove the complete actuator element.

Remove the entire valve head (4) complete with guide rod (9) and spring (10).

Clean the individual parts, check for damage and if necessary replace.

Lubricate the seal and friction surfaces and O-rings.

Follow the above procedure in reverse to reassemble the quick drain valve.

Caution: It is not permissible to change response pressure by adjusting the set screw (12).

Return to service the deluge valve set in accordance with the operating regulations.

Carry out a final check on the quick drain valve as described above.

A deviation of ±0.3 bar from the response value marked on the valve means that it must becompletely replaced.

5.4 Diaphragm valve maintenance regulations (Fig. 18)

The diaphragm valve is used for pneumatic actuation of the deluge valve set. When the valve is in itsREADY state compressed air in the diaphragm chamber holds the valve head closed against the waterpressure in the deluge valve. When the pressure in the diaphragm chamber falls to approx. 1/6 of thewater supply pressure the valve head opens and depressurises the control chamber of the deluge valve.

In order to maintain the READY state of the valve an adequate supply of compressed air to thediaphragm chamber must be assured (automatic replenishment of compressed air and, if necessary,electrical supervisory switch).

When carrying out maintenance, close the deluge valve set inlet and outlet gate valves anddepressurise the control chamber using the vent valve.

As a basic rule, it is a good idea to unscrew the complete diaphragm valve from the deluge valve and toobserve the following sequence when carrying out maintenance in a vice:

Unscrew and remove the complete control component at the position marked X - X.

Unscrew the diaphragm cover (11).

Clean diaphragm (1) and valve head (3), check for damage and if necessary replace.

Check the piston rod (9) for smooth action and if necessary clean and lubricate.

Lubricate friction surfaces, O-rings and seal surfaces.

Reassemble the diaphragm valve and reinstall it in the deluge valve set.

After returning the deluge valve set to service, carry out a test release by reducing the pressure in thediaphragm chamber of the diaphragm valve.
