INSTALLATION, OPERATION and

MAINTENANCE

1” Figure 945 Combination Air Valves

INTRODUCTION

This manual will provide the information to
properly install, operate and maintain the valve
to ensure a long service life. The Combination
Air Valve is ruggedly constructed to provide
years of trouble-free operation with minimal
maintenance.

Figure 945 Combination Air Valves are not
intended for use with fluids containing
suspended solids such as wastewater and
sewage. GA Industries Figure 942, 955, 957 or
959 Combination Air Valves are recommended
for such applications.

CAUTION

The valve is NOT recommended for use with
toxic fluids, fuels or fluids containing hazardous
gases

CAUTION

The valve will not function if used at a pressure
higher than the maximum working pressure
indicated on the nameplate.

The Shop Order (SO) Number, Figure Number,
size and pressure rating are stamped on a
nameplate attached to the valve. Please refer to
the SO number when ordering parts.

DESCRIPTION OF OPERATION
The Figure 945 Combination Air Valve performs
the following functions:

• Vents air through the large orifice ahead
of the incoming water as the system is
filled then closes tightly to prevent the
escape of water.

• Automatically opens and closes the
small orifice as often as needed to
release air that has accumulated in the
valve while the system is pressurized
and operational

• Opens automatically to admit air through
the large orifice to limit vacuum pressure
within the pipe or system.

RECEIVING AND STORAGE

Inspect the valve upon receipt for damage
during shipment. Carefully unload all valves to
the ground without dropping.

The valves should remain in a clean, dry and
weather protected area until installed. For long
term storage (greater than 6 months) the rubber
surfaces of the seat should be coated with a
non-toxic lubricant such as "SuperLube" made
by Synco Chemical. Do not expose the rubber
parts to sunlight or ozone.

INSTALLATION

The 1” Figure 945 is standard with NPT screwed
connections and reducer bushings are provided
for smaller sizes.

Consult the drawings of record to verify the
configuration supplied and installed.

The valve must be installed in an upright vertical
orientation, normally at a high point in the
system.

If installed outdoors, below ground in a vault or
in an unheated area, adequate freeze protection
must be provided. Some discharge of water
may occur during operation so the valve outlet
should be piped to an adequate drain.

An isolating valve should be installed between
the valve and the pipeline or system to facilitate
maintenance.

Carefully screw threaded end valves onto pipe
nipple using compatible thread sealant. Tighten
valve using wrench flats. DO NOT OVER­TIGHTEN.

Flat-faced flanged valves should be mated with
flat-faced flanges and full-face gaskets. If ring
gaskets are used the bolt material shall be
ASTM A307 Grade B (or equivalent). Higher
strength bolting should only be used with full­face gaskets.
