Product Summary

A Double Door Check Valve is a type of check valve with a double door member. The body houses a pair of check valve seats on opposite sides of the access opening for seating a pair of check valves mounted in series to permit flow from the inlet opening to the outlet openings. The prime function of a double door 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.
