It requires regulated dry air supply with main supply

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/.

User must install non return valve at air supply

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

be provided, which acts as a manual reset device

in the dry pilot line.

TRIM TYPES

The trims are designated as follwing.

W =Wet Pilot trim. D = Dry Pilot 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 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.

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 & announciation 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 & announciation

are optional.

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.

c) Type ETW-T and ETD-T

This trim type is a combination of components of

the ET trims along with the test and alarm trim.

In dry pilot trim, an actuator DPA-H1 is provided

with optional Pneumatic Reset Device (PRD-1).

A solenoid valve for electric remote actuation

and pressure switch for sensing & announciation

are optional.

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.

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 & announciation are optional.
