FIG. 3800 Single Small Air Release Valve
Wide range of materials Aluminium Bronze, Super Duplex, Stainless Steel, Titanium, 6MO, Hastelloy®, Monel®, Inconel® & Gunmetal.
Usage for petrochemical, sea water & offshore markets
During normal working of the main the valve releases the air which accumulates under pressure. With the main in operation, the float is normally 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.
Lightweight design.
2.3mm (4.1mm2) orifice.
FIG. 8316 Single Large Air Release Valve
Wide range of materials Aluminium Bronze, Super Duplex, Stainless Steel, Titanium, 6MO, Hastelloy & Gunmetal.
Large orifice air valves allow air to be expelled from the system during filling of a pipeline and admit air back into the system whenever sub-atmospheric pressure occurs.
Air is vented from the system until water enters the valve and lifts the float against its seat ensuring a tight seal. In the event of subatmospheric pressure in the system, the water level drops causing the float to fall from its seat and allow the admission of air.
Efficient low pressure sealing at 0.2bar
25mm (1″) − 200mm (8″) sizes.
FIG. 8340 Double Air Release Valve
Wide range of materials Aluminium Bronze, Super Duplex, Stainless Steel, Titanium, 6MO, Hastelloy & Gunmetal.
Double orifice air valve that combines both large orifice & small orifice functions within one unit. The large orifice allows air to be expelled from the system during filling of a pipeline and admit air back into the system whenever sub atmospheric pressure occurs.
Air is vented from the system until water enters the valve and lifts the float against its seat, ensuring a tight seal. In the event of sub-atmospheric pressure in the system, the water level drops causing the float to fall from its seat and allow the admission of air.
During normal working of the main the small orifice releases the air which accumulates under pressure. With the main in operation, the float is normally against its seat.

The consequent rise in water level returns the float to its seat

FIG. 925 Single Small Orifice Air Release Valve
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.

Inflow / outflow check.
Flushing attachment.
Drainage boss.
Isolating gate valve with or without bevel gearbox.
Odour control unit.
25 bar version.
FIG. 942 Double Orifice Air Release Valve
Double orifice air valve that combines both large orifice & small orifice functions within one unit. The large orifice allows air to be expelled from the system during filling of a pipeline and admit air back into the system whenever sub-atmospheric pressure occurs.
Air is vented from the system until liquid enters the valve and lifts the float on its pivot which lifts the plug against the large orifice seat. Pressure within the body holds the plug firmly against the seat. In the event of sub-atmospheric pressure in the system, the liquid level drops causing the float and plug to lower and allow the admission of air.
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 normally holds the orifice button against its seat.
As air enters the body the fluid level is depressed until a level is reached when the float drops, which allows air to vent through the small orifice. The consequent rise in fluid level returns the float and orifice button to its seat.
Efficient low pressure sealing at 0.2bar.
50mm (2″) − 150mm (6″) sizes.
