pass check valve and restriction orice 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 re 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 allow-
ing the water ow 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 and Alarm
Trim as per the method of actuation of the deluge
valve. The functionality of these trims is described
below.
a) DRY PILOT TRIM (PNEUMATIC RELEASE)
Dry pilot operation uses a pilot line of closed Sprin-
kles/QB detectors containing air under pressure,
located in the area to be protected. It requires reg-
ulated dry air supply with main supply point through
restricted orice. The air pressure to be maintained
as specied in the catalogue of Dry Pilot Actuator.
The pilot line is connected to air inlet side of actua-
tor. The top chamber of the deluge valve is con-
nected to water inlet side of actuator.
When there is an air pressure drop, or due to re-
lease of any of the release device on detection of
re, the diaphragm of actuator is lifted and allows
the water to drain. This releases the water pressure
DESCRIPTION
Deluge Valve is known as a system control valve in a deluge sys-
tem, used for fast application of water in a spray system. Deluge
valve protects areas such as power transformer installation, stor-
age tank, conveyor protection and other industrial application etc.
With the addition of foaming agent deluge valve can be used to
protect aircraft hanger and inammable liquid re.
VALVE OPERATION
SHIELD 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 by-

in the top chamber of the deluge valve, allowing the del-
uge valve to open and water to ow 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.
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 orice. All the release lines are connected to
a common release line. Due to release of any one of the
release 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 is provided to test
the normal operation of the sprinkler alarm bell. The sprin-

RESETTING PROCEDURE FOR THE
DELUGE VALVE
(i) Close the upstream side stop valve provided below the
deluge valve
ii) Open both the drain valves/ drain plugs and close when
the ow of water has ceased
(iii) Close the release device/replace the Sprinkler if re-
lease was through Sprinkler/QB Detector
iv) Inspect and release if required, or close the section of
the detection system subjected to “Fire condition”
(v) In case of dry pilot detection system, open the air sup-
ply valve to build-up air pressure. Open the priming valve
fully. Open the upstream side of the stop valve provided
below the Deluge valve. No water should ow into the sys-
tem.
vi) Where priming shut off valve (optional) is provided for
resetting, then the water need to be drained from up-
stream side of valve.
NOTE :
The valve can be reset without undergoing above proce-
dure, by just closing/replacing the release device as valve
is auto reset type. The reset time may be long or cause
vibration while closing depending on back pressure at the
outlet of the valve.
CAUTION
(a) Do not close the priming valve, downstream and up-
stream stop valves, while the 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 limita-
tion graph.
(d) Do not connect the Sprinkler Alarm outlet drain line to
close a common drain as it may create back pressure and
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 ow
from all open system valves.
(g) The responsibility of maintenance of the protection sys-
tem 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 presssurised system
SYSTEM TESTING PROCEDURE
(i) Keep the upstream side of the stop valve partially open.
To avoid water ow 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 head-
ing “RESETTING PROCEDURE FOR THE DELUGE VALVE”
INSPECTION AND MAINTENANCE
Installed system piping network must be ushed properly
before placing the Deluge valve in service.
A qualied and trained person must commission the sys-
tem. 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 accord-
ance to the organisation having local jurisdiction.
(i) WARNING
Inspection and testing is to be carried out only by author-
ised 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 re 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 veri-
fy 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 pres-
ence of contaminated water supplies, corrosive/ scaling
water supplies, and corrosive atmospheres.
