SWING CHECK VALVE

1 piece bolted bonnet design holding a disc that swings on an hinge.

Swing check valves prevent backflow, ensure the unidirectional flow of fluids and have the minimal pressure decline through the valve.

The valves do not rely on lubricant or grease to assist sealing.

Suitable for: FPSO, LNG Terminal, Offshore, Onshore, Pipeline Transportation, Power and renewvables, Refinery and petrochemical, Water desalination
