FIG. 925 SINGLE SMALL ORIFICE AIR RELEASE VALVE

Features
Usage for waste & sewage water.
During normal working of the main the valve releases the air which accumulates under pressure without escape of fluid..
With the main in operation, the float holds the orificebutton against its seat.
As air enters the body the water level is depressed until a
level is reached when the float drops from its seat, which allows air to escape.
The consequent rise in water level returns the float to its seat.
Efficient low pressure sealing at 0.2bar.
WRAS approved.
