FVF BS 5352 Forged Steel Socket Weld Swing Check Valve Class 800

FVF forged check valve is an automatic valve. Its main function is to prevent the backflow of the medium, prevent the reversing of the pump and drive motor, and the discharge of the container medium.The check valve can also be used to supply pipelines where the pressure may exceed the system pressure.
The check valves are opened and closely automatically by the flow of the medium itself, and prevent the reverse flow of the medium.
The check valve is available in three different design configurations. These are piston check, ball check, or swing check designs.
