INSTALLATION, OPERATION and
MAINTENANCE
Figure 929 Sewage Air Release Valves
INTRODUCTION
This manual will provide the information to properly install, operate and maintain the valve to ensure a long service life. The Air Release Valve is ruggedly constructed to provide years of trouble-free operation with minimal maintenance.
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 929 Air Release Valve is designed to automatically vent air and sewage gas that has accumulated within the valve. These valves are usually installed at high points in the system where air tends to collect. The valve as shipped is ”normally open” and will vent air through its orifice at the top of the valve. The float rises when water enters the valve and closes the orifice. Air from the system accumulates in the valve forcing the water level down until the float drops and opens the venting orifice. As air is released the water level rises lifting the float and re-closing the valve.
This sequence occurs as often as necessary to release air that has collected in the valve.
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 Figure 929 is standard with 2” or 3” NPT pipeline connection. A flanged pipeline connection is provided on special order.
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.
An isolating valve should be installed between the valve and the pipeline or system to facilitate maintenance (included with backflushing attachments).
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.
Lower heavy valves over the mating flange using slings or chains around the valve body. Lubricate the bolts or studs and insert around flange. Lightly tighten bolts until gaps are eliminated. Torque bolts in an alternating
