Triple Function Combination Air Release Valve Anti Shock EN1074-4 And AWWA C512
Features:
Anti-shock combination air release valve can 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.
