Three Function Combination Air Release ValveAnti Shock

 

 

 

Features:

 

Anti-shock combination air release valve can prevent water hammer. It can decreas 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.
