DESCRIPTION
Deluge Valve is known as a system control valve in
a deluge system, used for fast application of water
in a spray system. Deluge valve protects areas such
as power transformer installation, storage tank,
conveyor protection and other industrial application
etc. With the addition of foaming agent, deluge valve
can be used to protect aircraft hanger and inflammable
liquid fire.
VALVE OPERATION
HD Deluge Valve is a quick release, hydraulically
operated diaphragm valve. It has three chambers,
isolated from each other by the diaphragm operated
clapper and seat seal. While in SET position, water
pressure is transmitted through an external bypass
check valve and restriction orifice from the system
supply side to the top chamber, so that supply
pressure in the top chamber act across the diaphragm
operated clapper which holds the seat against the
inlet supply pressure, because of the differential
pressure design. On detection of fire, the top chamber
is vented to atmosphere through the outlet port via
opened actuation devices. The top chamber pressure
cannot be replenished through the restricted inlet
port, and the upward force of the supply pressure
lifts the clapper allowing the water flow to the system
piping network and alarm devices.

TRIM DESCRIPTION
The trims are functionally termed as Dry Pilot Trim,
Wet Pilot Trim, Electric Trim and Test & Alarm Trim as
per the method of actuation of the deluge valve.
The functionality of these trims are described below:
a) DRY PILOT TRIM (PNEUMATIC RELEASE)
Dry pilot operation uses a pilot line of closed
Sprinklers/ QB Detectors containing air under
pressure, located in the area to be protected.
It requires regulated dry air supply with main
supply point through restricted orifice. The air
pressure to be maintained as specified in the
catalogue of Dry Pilot Actuator (HD 252). The
pilot line is connected to air inlet side of actuator.
The top chamber of the deluge valve is connected
to water inlet side of actuator.
When there is an air pressure drop, or due to
release of any of the releasing device on detection
of fire, the diaphragm of actuator is lifted and
allows the water to drain. This releases the water
pressure in the top chamber of the deluge valve,
allowing the deluge valve to open and water to
flow into the system piping & alarm devices.
Recommended air supply pressure for dry pilot
trim system is 3.5 kg/sq.cm.
User must install non return valve at air supply
connection to deluge valve trim.
In dry pilot trim, an actuator (DPA) is provided.
An optional Pneumatic Reset Device (PRD) can
be provided, which acts as a manual reset device
in the dry pilot line.
b) WET PILOT TRIM (HYDRAULIC RELEASE)
Wet pilot operation uses a pilot line of closed
Sprinklers/QB Detectors containing pressurized
water, supplied through the upstream side of
the Deluge valve, through a restricted orifice. Due
to release of any one of the releasing device, the
water pressure in the top chamber of the Deluge
valve drops and the Deluge valve opens.
c) ELECTRIC RELEASE TRIM
To actuate a Deluge valve electrically, a solenoid
valve is provided to drain the water from the top
chamber of the Deluge valve. A pressure switch is
provided to activate an electric alarm, to shut
down the desired equipment or to give “Tripped”
indication of the Deluge valve. In addition to this a
pressure switch can also monitor “Low air
pressure” and “Fire condition” when used in dry
pilot air line.
d) TEST AND ALARM TRIM
This trim is supplied with a test valve provided to
test the normal operation of the sprinkler alarm
bell. The sprinkler alarm can be supplied additionally,
which bells on actuation of the Deluge valve.
e) DRAIN AND DRIP TRIM
This consists of main and system drain valve in
addition with drip valve.

a) Type ET-W and ET-D
This type of trim is basic trim required to
operate the deluge valve. A solenoid valve for
electric remote actuation and pressure switch
for sensing & annunciation are optional.
b) Type ETW-D and ETD-D
This trim type is a combination of components
of the ET trim along with the drip and drain
trim. A solenoid valve for electric remote actuation
and pressure switch for sensing & annunciation
are optional.
c) Type ETW-T and ETD-T
This trim type is a combination of components of
the ET trims along with the test & alarm trim.
A solenoid valve for electric remote actuation
and pressure switch for sensing & annunciation
are optional.
d) Type NT-W and NT-D
This trim type is a combination of components of
the ET trim along with the test and alarm trim
as well as the drip and drain trim. A solenoid valve
for electric remote actuation and pressure switch
for sensing & annunciation are optional.
RESETTING PROCEDURE
A. When priming connection is below the upstream
valve (Stop Valve)
(i) Close the upstream side stop valve provided below
the deluge valve to cease the flow of water.
(ii) Open both the drain valves/ drain plugs and close
when the flow of water has ceased.
(iii) Close the release device/replace the Sprinkler if
release was through Sprinkler/ QB Detector.
(iv) Inspect and restore/ replace/ repair if required,
the section of the detection system subjected to
“Fire condition”.
(v) In case of dry pilot detection system, open the
air supply valve to build-up air pressure. Open the
priming valve fully. When top chamber pressure is
more than 50% of the inlet pressure, open the
upstream side of the stop valve provided below
the Deluge valve. No water should flow into the
system.
(vi) When priming shut off valve (optional) is provided
for resetting, then the water need to be drained
from upstream side of valve.
B. When priming connection is from the inlet of
Deluge Valve (Auto resetting)
(i) The deluge valve will reset automatically when
releasing devices which were responsible for
deluge valve opening are closed or restored
back to their original status (i.e closing of ERS
or replacing the damaged Sprinkler if release
was through Sprinkler/ QB Detector or closing
of Solenoid valve). The reset time may be long or
cause vibration while closing depending upon the
system back pressure at the outlet of the valve.
CAUTION
(a) Do not close the priming valve, downstream and
upstream stop valves, while system is in service
(b) The releasing device must be maintained in the
open position, when actuated, to prevent the
deluge valve from closure if anti shut off valve is
not provided
(c) While using a deluge valve in the wet pilot system
the height and the length of the wet pilot
detection line is to be limited as shown in
the wet pilot sprinkler height limitation graph
(d) Do not connect the Sprinkler Alarm outlet drain
line to close a common drain as it may create
back pressure & Sprinkler Alarm may not function
(e) Deluge valve must have support to absorb sudden
opening or closing vibration shock to the piping
(f) To avoid water damage, take precautions when
opening the water supply main control valve, since
water will flow from all open system valves
(g) The responsibility of maintenance of the protection
system and devices in proper operating condition
lies with the owner of the system.
(h) Deluge Valve & its trim shall be maintained at a
minimum temperature of 4oC. Heat tracing is not
permitted.
(i) Deluge Valve must be used in pressurised system.
SYSTEM TESTING PROCEDURE
(i) Keep the upstream side of the stop valve partially
open. To avoid water flow to system side, close the
system side stop valve. This valve is to be kept in
open position after the testing is completed.
(ii) Let any of the release devices to trip. This will
result in a sudden drop of water pressure in
the deluge valve top chamber which in turn will
open the deluge valve. Close the upstream side
stop valve immediately.
(iii) Reset the valve as per the procedure given
under heading “RESETTING PROCEDURE FOR THE
DELUGE VALVE”

INSPECTION AND MAINTENANCE
Installed system piping network must be flushed
properly before placing the Deluge valve in service.
A qualified and trained person must commission
the system. After few initial successful tests,
an authorized person must be trained to perform
inspection and testing of the system. It is
recommended to have regular inspection and test run
of the system as per NFPA guideline or in accordance
to the organisation having local jurisdiction.
(i) WARNING
Inspection and testing is to be carried out only by
authorised and trained personnel. DO NOT TURN
OFF the water supply or close any valve to make
repair(s), or test the valve without placing a
roving fire patrol in the area covered by the
system. Also inform the local security personnel
and central alarm station, so that there is no
false alarm signal.
It is recommended to carry out physical inspection
of the system at least twice in a week. The
inspection should verify that all the control valves
are in proper position as per the system
requirement and that there are no damages to
any component.
The frequency of inspections must be increased
in the presence of contaminated water supplies,
corrosive/scaling water supplies, and corrosive
atmospheres.
(ii) NORMAL CONDITION
(a) All main valves are open and are sealed with
tamper proof seal
(b) Drain valves must be kept closed
(c) No leak or drip is detected from the drip valve
(d) All the gauges except the system side water
pressure gauge, should show the required
pressure
(e) There should be no leakage in the system
(iii) NORMAL CONDITION TEST
(a) The system should be checked for normal
condition at least once in a week
(b) Test the sprinkler alarm bell or electric alarm
by turning the alarm test valve to the test
position. The alarm should sound. This test should
be carried out at least once in a week
(c) Depress the drip valve knob. Significant
accumulation indicates a possible seat leakage
(d) Conduct the water flow test as per the system
testing procedure at least once a month
(iv) PERIODIC CHECK
Conduct the water flow test by actuating few of
the release devices provided in the system. Clean
all strainer(s) and line restriction nipple. This
test is to be carried out at least once in three
months.
ABNORMAL CONDITION
(i) ALARM FAILS TO SOUND
(a) Check for any obstruction in the alarm test
line, make certain that the sprinkler alarm is free
to operate
(b) If an electric alarm is provided, check the
electrical circuitry to the alarm
(ii) FALSE TRIPS
(a) Check for clogging in priming line, restriction
orifice check valve, priming valve & strainer
(b) Leakage in the release system
(c) The deluge air line restriction orifice clogged or
low supply pressure
(iii) LEAKAGE THROUGH THE DELUGE VALVE
(a) Damaged deluge valve seat or obstruction on
the seat face by foreign object
(b) Leakage in release system
(c) Partly clogged priming line restriction orifice
check valve
(d) Low air pressure on release system line or
leakage in release system
NOTE:
(1) UL Listing is valid only when Deluge Valve is
installed with trim set as per trim drawing.
(2) The trip time of deluge valve on-off device through
detection network, will depend on volume of
detection network. If the trip time of deluge valve
is more, then it can be substantially reduced by
installing check valve in branch of release line in
the detection network. The check valve flow shall
be towards releasing device.
(3) The pneumatic system must have restricted
orifice at air or gas supply point. The restriction
nozzle are supplied with HD dry pilot actuation
trim.
(4) UL Listing is valid only when Listed Solenoid Valve
provided for electric operation of the deluge valve
is retained in the trim. If any other solenoid valve
is used, the deluge valve trip time may be quite
high or deluge valve may not trip.
(5) The Pressure Gauges standard supply is 300 psi
for water gauge for system pressure upto 175
psi. If system pressure is more than 175 psi,
then order for 600 psi water pressure gauges.
