Product Summary

The screwed check valve is a type of check vale whose valve body is designed with a screwed member. The prime function of a check valve is to protect mechanical equipment in a piping system by preventing reversal of flow by the fluid.

This is particularly important in the case of pumps and compressors, where back flow could damage the internals of the equipment and cause an unnecessary shutdown of the system and in severe cases the complete plant. This mode of flow regulation is required to prevent return flow, to maintain prime after the pump has stopped, to enable reciprocating pumps and compressors to function, and to prevent rotary pumps and compressors from driving standby units in reverse.
