Check valves prevent reverse flow and protect pumps, equipment and piping systems. The correct type depends on the medium, flow direction, installation orientation, pressure conditions and the acceptable pressure drop.
Common check valve options
- Swing check valves for common water and general process systems.
- Lift check valves where a guided closure arrangement suits the service.
- Wafer check valves for compact installation between flanges.
- Marine and suction configurations for specific shipboard requirements.
Information needed for selection
Please provide size, pressure rating, pipe connection, medium, temperature, mounting orientation, required body and trim materials, and any certificate requirement. For pump systems, include flow conditions where possible so closing behavior can be considered.
