Anti shock Triple Function Combination Air Release Valve Single Body
Features:
Anti-shock combination air release valve can help to prevent water hammer. It decreased the water velocity and restrict the velocity of air flow. This type of valve is generally used in long water transmission pipeline where may occur a water hammer. If the air exhaust out the valve too quick, the water will comes in very fast, too. The water will prevent the float go up which caused the valve leaking.
AFC's air release valve conforms to International standard EN1074-4 and AWWA C512.
Compared with other plant air valve, ours have not only large air exhausting and large air intake under invacuum,but also one more function of small air releasing.
Our air valve is 100% full bore(inlet-outlet),simple components,valve body and bonnet, float,seal arc, guide barrel etc,most of them can be recycled-evironmental. Single valve chamber,unlike many connected bodies are easy to break up during transportation. All internal accessories are of AISI 304SS, hardness and quality are quaranteed.
There is a seal gasket in the valve above big float and it helps orifice make better sealing effect. With rubber seal gasket above float, it can absorb water hammar to avoid crash with seal arc and valve body and protect air valve from hurting.
