Disc Check Valve
Check valves are two-port valves, meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave. A check valve is a valve that normally allows fluid to flow through it in only one direction.
There are various types of check valves used in a wide variety of applications. Disc Check Valves are designed to be sandwiched between flanges i.e. wafer type.
These check valves can be mounted between pipe flanges in any direction.
