Product Summary

A three piece check valve is a special check valve form which is presented in the form of three pieces.

The basic duty of these three piece check valves is still to prevent back flow. However, the valves should also close fast enough to prevent the formation of a significant reverse-flow velocity, which on sudden shut-off, may introduce an undesirably high surge pressure and/or cause heavy slamming of the closure member against the seat. In addition, the closure member should remain stable in the open valve position. 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.
