Swing Check Valves

  • Description

    FLUIDCHEM make Swing Check/Non-Return Valves are designed and manufactured as per BS1868. Check Valves are widely essential in the Piping System of every field. Check Valves prevent reverse flow of fluid during the failure or abrupt shut-down of Piping System

    FLUIDCHEM’s Swing Check Valves have a precisely guided swinging disc through a Hinge. The Hinge and swivel disc are linked to maintain adequate flexibility so that the sealing is smooth and efficient. FLUIDCHEM’s Swing Check Valves are available with Metal-to-Metal sealing to handle High Temperature and Pressure and Soft Sealing to take care of Pneumatic and Vacuum applications. The design guarantees that the Valve functions smoothly with a very nominal differential pressure from either side. The disc is designed to make it compact and light weight to make sure that there is least pressure drop across the Valve.


    FLUIDCHEM’s check valves are ideally suitable for horizontal application. These Check Valves (Non-Return Valves) are suitable for oil, gas, water, refining, power and chemical applications where the prevention of flow reversal is mandatory.
