FIG. 8316 SINGLE LARGE AIR RELEASE VALVE

Features:
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.

Suitable for:

Petrochemical Valves

Valve type:
