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 and Alarm
Trim as per the mehod of actuation of the deluge
valve.
The functionality of these trims is described below..
a) DRYPILOT TRIM (PNEUMATIC RELEASE)
Dry pilot operation uses a pilot line of closed
Sprinkles/QB detectors containing air under
pressure, located in the areato be protected. It
requires regulated dry air supply with main supply
point through restricted orifice. The air pressure
to bemaintained as specified in the catalogue of
Dry Pilot Actuator. 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 release 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. 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 thenormal operation of the sprinkler
alarm bell. The sprinkler alarmcan 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.

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 flow of water has ceased
(iii) Close the release device/replace the Sprinkler
if release 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 supply 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 flow into the system
vi) Where priming shut off valve is provided for
resetting, in addition to above steps press the
knob on actuator while resetting
CAUTION
(a) Do not close the priming valve, downstream
and upstream 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 limitation 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 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
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

:E>5" !# PAGE 4 OF 17 HD 235
(c) Depress the drip valve knob. Significant
accumulation indicates a possible seat
leakage
(d) Conduct the water flow test as per the
procedure of system testing 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 priming line restriction. 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
