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.

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

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.

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.
