VAL-MATIC'S AIR RELEASE VALVE
OPERATION, MAINTENANCE AND INSTALLATION
INTRODUCTION
This manual will provide you with the information
to properly install and maintain the valve to
ensure a long service life.
Valve has been designed with stainless steel
trim to give years of trouble-free operation. The
Air Release Valve is typically mounted at the
high points in a piping system to automatically
remove pockets of air as they accumulate. The
valve can also be used to slowly release air in
tanks and pump casings.
Note: This valve is not intended for fluids
containing
suspended
wastewater.
For wastewater and other high
turbidity applications, use Val-Matic Series 48A
& 49A Sewage Air Release Valves.
CAUTION
This valve is not intended for fuel service
or fluids containing suspended solids.
The valve is a float-operated, resilient-seated
valve designed to handle clean fluids.
Maximum Working Pressure and Model No. are
stamped on the nameplate for reference.
Note: Low Durometer seats are available for low
pressure applications.
RECEIVING AND STORAGE
Inspect valves upon receipt for damage in
shipment.
Handle all valves carefully without
dropping. Valves should remain boxed, clean
and dry until installed to prevent weather related
damage. For long term storage greater than six
months, the valve must remain in the box and
stored indoors. Do not expose valve to sunlight
or ozone for any extended period.

shipped, is a normally open valve and will slowly
vent air through the top orifice. As fluid enters
the valve, the float will rise, closing the orifice.
As air accumulates in the piping system and
enters the valve, the float drops allowing the
venting orifice to open.
The lever mechanism provides mechanical
advantage for the float.
operation, the pipeline pressure exerts a strong
upward force on the sealing component, the
orifice button. The lever mechanism magnifies
the weight of the float so that the orifice will open
under high pipeline pressures. Additional ports
are provided for flushing, testing and draining
purposes.
