Inbal Valves 700D Series Instruction manual

Model 799D
Automatic Water Control Valve
Series 700D
F02-01-02
General Description
The Inbal Automatic Water Control
Valve series 700D is a pressure operated,
sleeve actuated, axial valve, designed
from basic concepts, with a built-in
actuator to function as control valve in
fire protection system. The Inbal series
700D is used as deluge, preaction, dry
pipe, remote control, pressure reducing,
pressure relief, pump control, water level
control, and other types of control
valves. The standard material Inbal
Valve is rated to 300 psi (21 bar) and
requires a minimum line pressure of 20
psi (1.5 bar) for operation. Upon removal
of the control pressure the Inbal Valve
opens instantaneously, yet very
smoothly, to prevent any water hammer
in the piping system. The Inbal 700D
performance and ease of resetting are not
affected by vertical or horizontal
installation.
The Inbal Automatic Water Control
Valve utilizes the unique N.M.M.P. (No
Moving Mechanical Parts) design. The
only moving part when the Inbal Valve
operates, is the reinforced sleeve which
forms a drip-tight seal with the corrosion
resistant core. The Inbal design also
prevents false operation due to transient
surges in water supply pressure. The
N.M.M.P. design and variety of mater-
ials and coatings make the Inbal Auto-
matic Water Control Valve ideally
suitable for use with brackish or sea
water similar to those found in chemical
and petrochemical facilities or in
offshore platforms. It can also be used as
a foam concentrate control valve in
foam/water systems.
The Inbal Automatic Water Control
Valve series 700D is available in sizes
1½" (40 mm) to 12" (300 mm). The
valves have threaded, flanged, or wafer
inlet and outlet ends.

Full open operation
When pressure in the Control Chamber is
relieved to the atmosphere, the Inbal
Valve opens wide. The sleeve assembly
is safely enveloped by the housing.
Tight closing operation
When pressure from the valve inlet (or an
equivalent independent operating
pressure) is applied to the Control
Chamber, the Inbal Valve closes drip
tight. The fabric sleeve safely envelopes
the resilient sleeve giving full support.
Modulating action
A stable throttling position is obtained
when a quantity of pressurized fluid is
held in the Control Chamber. It is the
amount of fluid in the Control Chamber
that determines the position of the sleeve
assembly. The Control Chamber can be
alternately filled or exhausted to achieve
the desired operating condition.

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.
In the set position, the water pressure is
transmitted from the upstream through
the valve trim to the Control Chamber,
and the Inbal Valve stays closed.
Actuation of the valve by a manual,
hydraulic, pneumatic, or electric release
system allows venting of the pressure in
the Inbal Valve Control Chamber, and
the valve opens wide, permitting a flow
of water to the piping system. When a
pressure or flow control is added, the
Control Chamber is monitored to
modulate a preset delivery pressure,
maximum inlet pressure, or flow rate.
The principle of operation is illustrated
in Figures (1) through (3). The nominal
pressure losses are shown in Graph (1).
Installation
Refer to the Trim Chart applicable to the
specific Inbal Valve model in use.
1. When the Inbal Valve is delivered,
carefully unpack and visually check
that there has been no damage to the
operating components, piping, and
fittings.
2. The Inbal Valve must be installed in
an area not subject to freezing
conditions.
3. Always flush the pipelines before
installing the valve.
4. Place the Inbal Valve in the piping in
the outlet of the Water Supply Valve.
Verify that the arrow on the valve
housing matches the actual flow
direction. The Inbal Valve may be
installed in any position. Determine
which side the valve will be accessed
from and locate all the components
accordingly.
5. Install the Inbal Valve in the piping
system. Refer also to the applicable
Installation Guide.
Threaded End Valve - connect the
female threaded ends of the Inbal
Valve to the male threads of the
piping. Use the pipe joint compound
sparingly on the male threads only.
Flanged End Valve - connect with
bolts and nuts, the valve flanges to
the existing flanges in the piping
system, using gaskets in between.
Complete bolting with uniform
tightening.

Wafer End Valve - Install the Inbal
Valve between the piping flanges.
Place gaskets between the valve ends
and the pipe flanges. Insert four of
o
the stud bolts, 90 apart around the
valve, through the bolt sleeves and
the pipe's flanges, and tighten with
nuts. Complete bolting with uniform
tightening.
6. 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
and Installation Guide.
7. The pressure supply to the trim must
always be sourced from either inlet
of Water Supply Valve or Inbal
Valve upstream, through a ½" pipe.
8. Exhaust tube must be free of any back
pressure. Provide an air gap between
the exhaust tube and drain facility.
9. Set the Inbal Valve by following the
applicable Resetting procedure.
10. Test the Inbal Valve, the trim, and
alarms according to the applicable
Testing procedure.
Resetting
The Inbal Automatic Water Control
Valve system must be reset and restored
to service as soon as possible after
automatic, emergency, or manual
actuation. Refer to the relevant bulletin
for detailed procedure.
