    Popular 2 inch check valve comes with a 50mm nominal diameter, 16kg nominal pressure, high-temperature resistance, chemical resistance and corrosion resistance, CPVC swing type check valve can transport weak acid and alkali medium, widely used in water treatment and distribution systems, as well as industrial and commercial applications for handling various fluids.


    • The check valve can prevent the phenomenon of liquid counter-current from protecting the pump equipment.
    • Because it is a cantilever check valve, there is less resistance to flow.
    • The 2 inch swing check valve uses CPVC materials and plays a strong corrosion resistance to prevent acid and alkali fluid.
    • Not only can the valve body be removed from the pipeline, but also the valve cover can be opened for internal inspection and maintenance.

    Tips: Types of Check Valves

    Check valves are used in piping systems to allow flow in one direction while preventing flow in the opposite direction. There are several types of check valves, including:

    • Swing Check Valve: This type of check valve has a hinged flap that swings open when the fluid flows in the correct direction and closes to prevent backflow.
    • Ball Check Valve: This valve uses a ball to seal the flow. The ball is pushed against the seat to block the reverse flow, and when the forward flow returns, the ball is pushed away, allowing the fluid to flow through.
    • Tilting Disc Check Valve: In this type of valve, a disc tilts to allow flow in one direction and closes to prevent reverse flow.
    • Wafer Check Valve: This valve has a thin disk that is designed to fit between two flanges in a pipeline. The disk is held in place by the pressure of the fluid, allowing it to move freely when the fluid flows in the correct direction and closing to prevent backflow.
    • Lift Check Valve: This valve uses a piston or a ball to lift out of the way when the fluid flows in the correct direction and drops back into place to prevent reverse flow.
    • Diaphragm Check Valve: In this type of valve, a flexible diaphragm is used to allow flow in one direction and close to prevent reverse flow.
    • Stop Check Valve: This valve is similar to a lift check valve but also includes a mechanism to stop the flow in the forward direction.

    The selection of a check valve depends on the application, operating conditions, and the fluid being transported through the pipeline.

    Existing reviews of 2 inch Swing Check Valve, DN50, CPVC
    Well CPVC check valve
    It is a 2 inch chemical grade swing check valve which is very suitable for our sewage treatment plant. Corrosion resistance and chemical resistance are relatively high, which is what we need.
