Inbal Valves 700D Series User manual

General Description
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 use in fire protection systems.
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 manual release station is
operated locally 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 Deluge Valve resetting is
merely done by activating the reset knob.
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, or wafer inlet and outlet
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 any water hammer in the piping system.
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.

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 the dual purpose of
thermal detection and release system.
In the set position, water pressure is applied to the Control
Chamber of the Inbal Deluge Valve and to the hydraulic
release system from the upstream of the Water Supply
Valve. Consequently, the Inbal Deluge Valve stays closed.
Operation
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 procedure is
followed.
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 to the various
lengths of pilot lines and to the water supply pressure.
The Emergency Release Valve is used for emergency
actuation of the Inbal Deluge Valve and 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 visually check that there has been no
damage to the operating components, piping, and
fittings.
2. Always flush the pipelines before installing the Inbal
Valve.
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.
4. Install the Inbal Deluge Valve in the pipeline. Use
gaskets, bolts, stud bolts, bolt sleeves, and nuts as
required by the valve ends.
5. The Control Trim is supplied fully preassembled. Refer to
the applicable Trim Chart and Installation Guide.
6. The water pressure supply to the control trim must
always be sourced from the inlet of the Water Supply
Valve through a ½" pipe.
7. 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 sprinklers or manual release) should be
installed. An Anti-columning Device is required when the
release line elevation exceeds the figure corresponding
to the minimum water supply system pressure in which
the Inbal Deluge Valve is planned to perform.
8. It is recommended to install an inspector'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 to the smallest orifice of the releasing device
provided on the system. The inspector's test valve may
be used to verify adequate operation of the deluge
system when a releasing device operates.
9. Set the Inbal Deluge Valve by following the Resetting
procedure.
10.Test the Inbal Valve, the trim, and the alarms according
to the Testing procedure.

The procedure is as follows:
1.Close the Water Supply Valve. Water flow alarms are
reset.
2.Close the Trim Shutoff Valve.
3.Open the Flow Test Valve and Drain Valve, allowing all
the water to drain.
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 Valve is in a closed
position.
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 pressure
gauges are equal.
8.Release the reset knob on the Flow Release Pilot (F.R.P).
9.Close the Flow Test Valve.
10. Fully open the Water Supply Valve. Verify that there is no
flow from the Drain Valve, downstream of the Inbal
Valve.
11. Close the Drain Valve.
It is recommended that periodic inspections 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 recommended that the Deluge
Valve be tested, operated, cleaned, and inspected at least
on a routine basis.
A weekly Inspection is recommended:
1. Verify that the Water Supply Valve is sealed in fully open
position.
2. Verify that the required water pressure is being applied to
the Inbal Deluge Valve inlet and trim.
