Check Valves are an essential product offered by Wao-loc Instrumentations that helps customers in ways more than one.

SS Check Valves are automatic valves that open with the forward flow of the fluid and close with the reverse flow. The pressure applied by the liquid that passes through the system opens up the valve. On the other hand, any reversal flow will close this valve. Stainless Steel Check Valves are of two types; Swing Check Valve and Lift Check Valve. Duplex Steel Check Valves maintain pressure and prevent backflow. They are commonly used as a backup in case a pump fails to function. Some other uncommon types of Check Valves are Ball Check Valve, Water Check Valve, Umbrella Check Valve, etc.
