GeneralDescription

The Inbal Deluge Valve with Hydraulic

Actuation Trim is specifically designed

for fire protection systems actuated by a

fire detection and release system of wet

pilot sprinklers and/or hydraulic manual

control. The Inbal Automatic Water

Control Valve, which is used in this

deluge system, is a pressure operated,

sleeve actuated, axial valve designed for

useinfireprotectionsystems.

The Inbal Hydraulically actuated

Deluge Valve is used for automatic or

manual operation. The wet pilot line

functions as a thermal detector equipped

with a fixed temperature release. When

one or more of the sprinkler heads,

located on the pilot line, fuses, or when a

manualreleasestationisoperatedlocally

or remotely, the Inbal Deluge Valve

opens and water flows from all open

sprinklers and/or nozzles on the system.

As soon as the releasing system and the

sprinkler piping are reset, the Inbal

DelugeValve resetting ismerely done by

activatingtheresetknob.

The control trim includes all the pilot

valves, accessories, fittings, and gauges

to provide for proper operation in either

vertical or horizontal installation. The

standard material Inbal Deluge Valve is

rated to 300 psi (21 bar) and is available

in sizes 1½" (40 mm) to 12" (300 mm).

The valves have threaded, flanged,

grooved,orwaferinletandoutlet ends.

The only moving part in the Inbal

Deluge Valve, when it operates, is the

reinforced sleeve, which forms a drip-

tight seal with the corrosion resistant

core. It has a smooth opening to prevent

anywaterhammerinthepipingsystem.

The unique design and variety of

materials and coatings make the Inbal

Deluge Valve ideally suitable for use in

brackish or sea water, similar to those

found in chemical and petrochemical

facilities or in offshore platforms. The

Inbal can also be used as a foam

concentrate control valve in foam/water

systems.

Operation

The Control Chamber of the Inbal

Automatic Water Control Valve is the

annular space between the valve

Housing and the Sleeve. The valve is

held in a closed position as long as inlet

pressure is maintained in the Control

Chamber.

The wet pilot line, equipped with closed

sprinkler heads, is pressurized through

the valve trim and located over the

protected area. The wet pilot line serves

thedualpurposeofthermaldetectionand

releasesystem.

In the set position, water pressure is

applied to the Control Chamber of the

Inbal DelugeValve and to the hydraulic

release system from the upstream of the

Water Supply Valve. Consequently, the

Inbal DelugeValvestaysclosed.

The Inbal Deluge Valve opens wide

when one or more of the sprinklers

installed on the wet pilot line fuses and

water pressure is allowed to vent, or

when a hydraulic manual release opens.

Either one of these operations releases

water from the Inbal Control Chamber.

The Inbal Deluge Valve opens fully

introducing a flow of water to the system

while activating the system alarm

devices. Water will flow from any open

sprinklers and/or spray nozzles on the

system. The operation of the Inbal

Deluge Valve and the flow released from

the Control Chamber activate the Flow

Release Pilot (F.R.P) to latch in an open

position, isolating the Control Chamber

from the inlet water supply. The F.R.P

operation prevents the Inbal Deluge

Valve from closing even if the open

releasing wet pilot line closes. The Inbal

Valve will close only when the Resetting

procedureisfollowed.

The maximum elevations in which the

wet pilot sprinklers or manual release

stations can be installed are shown on

Graph (1).They are presented in relation

tothe various lengths ofpilotlines and to

thewatersupplypressure.

The Emergency Release Valve is used

for emergency actuation of the Inbal

DelugeValveand for routine testing.

Installation

Refer to the Trim Chart applicable to the

specific Inbal Deluge Valve model in

use.

1.When the Inbal Deluge Valve is

delivered, carefully unpack and visu-

ally check that there has been no

damageto the operatingcomponents,

piping,andfittings.

2.Always flush the pipelines before

installingtheInbalValve.

3.Place the Inbal Valve in the piping at

the outlet of the Water Supply Valve.

Verify that the arrow on the valve

Housing matches the actual flow

direction. Determine which side the

system will be accessed from and

locate the Inbal Deluge Valve

accordingly.

.Install the Inbal Deluge Valve in the

pipeline. Use gaskets, bolts, stud

bolts, bolt sleeves, and nuts as

required bythe valve ends.

.Complete the trim assembly by

connecting the preassembled

sections, or assemble the trim if

ordered in loose component form.

Refer to the applicable Trim Chart

andInstallationGuide.

.The water pressure supply to the

control trim must always be sourced

from the inlet of the Water Supply

Valvethrougha½"pipe.

.Connect the wet pilot line to the Flow

Release Pilot (F.R.P.). Refer to Graph

(1) which shows the maximum

elevations above the Deluge Valve at

which the release line (pilot sprink-

lers or manual release) should be

installed. An Anticolumning Device

is required when the release line

elevation exceeds the figure corres-

ponding to the minimum water

supply system pressure in which the

Inbal Deluge Valve is planned to

perform.

.It is recommended to install an inspe-

ctor's test valve on the hydraulic

release system. The inspector's test

valve is a locked closed ball valve

with an outlet end orifice equivalent

tothesmallestorificeofthereleasing

device provided on the system. The

inspector's test valve may be used to

verify adequate operation of the

deluge system when a releasing

deviceoperates.

9.Set the Inbal Deluge Valve by

followingtheResettingprocedure.

10.TesttheInbalValve,thetrim,andthe

alarms according to the Testing

procedure.

Resetting

The Inbal Deluge Valve system must be

reset and restored to service as soon as

possible after automatic, emergency, or

manualactuation.

Theprocedureisasfollows:

1.Close the Water Supply Valve. Water

flowalarmsarereset.

2.ClosetheTrimShutoff Valve.

3.Open the Flow Test Valve and Drain

Valve,allowingallthewatertodrain.

4.Inspect and replace any portion of the

detection system subjected to fire

conditions.

5.Inspect the trim and alarm Y-

Strainers.Clean if necessary.

6.Verify that the Emergency Release

Valveisinaclosedposition.

7.Open the Trim Shutoff Valve. Push

and hold the reset knob on the F.R.P.

and allow water pressure to build up

in the trim and in the Inbal Valve

Control Chamber. Wait and verify

that the pressure readings on both

pressuregaugesareequal.

8.Release the reset knob on the Flow

ReleasePilot(F.R.P).

9.Close theFlowTest Valve.

10.Fully open the Water Supply Valve.

Verify that there is no flow from the

Drain Valve, downstream of the

Inbal Valve.

11.Closethe DrainValve.

Maintenance,Inspection,&Testing

It is recommended that periodic inspec-

tions and tests be conducted by qualified

personnel to ensure that the Inbal

Deluge Valve and related equipment are

in good operating condition. The

inspection and testing activities should

be done according to NFPA Standards,

the guidelines and regulations of the

authorities having jurisdiction, and the

following instructions. It is recom-

mended that the Deluge Valve be tested,

operated, cleaned, and inspected at least

onaroutinebasis.

Inspection

Aweekly Inspection is recommended:

1.Verify that the Water Supply Valve is

sealedinfullyopen position.

2. Verify that the required water

pressure is being applied to the Inbal

DelugeValveinlet and trim.

DelugeTrimTesting

Asemi-annual Deluge Trim Testing

is recommended. Testing of the control

trim is conducted with no flow of water

tothesystem.

1.Open the Flow Test Valve to flush

away debris or foreign particles

which may have accumulated in the

Inbal Deluge Valve inlet.

2.Close the Flow Test Valve.

3.Close the Water Supply Valve

installed in the inlet of the Inbal

DelugeValve.

4.Open the inspector's test valve in the

hydraulic release system. Water

should be drained from the deluge

trim. Verify that the pressure reading

on the System Pressure Gauge drops

to zero which simulates an open

positionoftheInbalDelugeValve.

5.Reset the valve by performing the

instructionsinResetting.

Trip Testing

AnannualTripTestingisrecommended.

Performing the Trip Testing will cause

water to flow from all open sprinklers

and/or nozzles. Prevent damage by

takingnecessaryprecautions.

1.Open the Flow Test Valve to flush

away any debris or foreign particles

which may have accumulated in the

Inbal Deluge Valve inlet.

2.Close the FlowTest Valve.
