    Wholesale price 10 inch swing type check valve uses CPVC for chemical resistance, corrosion resistance and high-temperature resistance. 250mm swing check valve is commonly used in piping applications where reliable backflow prevention is required, such as water supply, wastewater treatment, irrigation and industrial processes.


    • 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 10 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: Why choose CPVC material for the check valve?

    CPVC (Chlorinated polyvinyl chloride) is a thermoplastic material that is frequently used for check valves in a variety of fluid-handling applications. Here are some reasons why CPVC may be a good choice for check valve material:

    • Corrosion resistance: CPVC is highly resistant to corrosion, making it an excellent choice for use in applications where the fluid being handled may be corrosive or aggressive.
    • Temperature resistance: CPVC can withstand a wide range of temperatures up to 95 degrees Celsius, making it suitable for use in high-temperature applications.
    • Mechanical strength: CPVC is a strong and durable material that can withstand high pressures and stress. It has a high tensile strength and can resist impacts and shock.
    • Chemical resistance: CPVC is resistant to a wide range of chemicals, including acids, alkalis, and organic solvents. This makes it a good choice for use in chemical processing plants, water treatment facilities, and other applications where exposure to chemicals is common.
    • Low thermal conductivity: CPVC has a low thermal conductivity, which means that it does not transfer heat as easily as other materials. This makes it a good choice for use in applications where heat loss or gain needs to be minimized.
    • Low flame spread: CPVC has a low flame spread rating and is self-extinguishing, making it a safe choice for use in applications where fire resistance is important.
