    Buy a 1 inch swing check valve at a low price. DN25, strong heat resistance & chemical resistance, low maintenance. Longlife CPVC swing type check valve can prevent backflow and ensure unidirectional flow in the piping system, perfect for chemical processing plants, water treatment facilities, etc.


    • 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 1 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: What is a swing check valve?

    A swing check valve is a type of valve used to control the flow of fluid in a pipeline. It is also commonly referred to as a "tilting disc check valve" or simply a "check valve."

    The valve consists of a hinged disc or flap that swings open to allow fluid to flow through the valve and swings closed to prevent backflow. When the pressure on the inlet side of the valve is greater than the pressure on the outlet side, the disc swings open, allowing the fluid to pass through the valve. When the pressure on the outlet side is greater than the pressure on the inlet side, the disc swings shut, preventing backflow.

    Swing check valves are commonly used in applications where backflow prevention is critical, such as in water and sewage treatment plants, irrigation systems, and industrial processes. They are available in a range of sizes, materials, and configurations to suit different applications and installation requirements.

    Well-sealed Swing Check Valve
    Recently, there is always able to smell an odor in our kitchen, for which we did a comprehensive cleaning, found that the source of the odor is the kitchen pipeline leakage, so it leads to the smell of the sewer floats up. We replaced this 1 inch swing check valve, it worked quickly and the odor was completely eliminated, and the installation is very simple, saving a lot of labor costs. Highly recommend this.

    It does the job well
    It took me a week to find this chemical grade CPVC swing check valve. It is more resistant to corrosion and high temperature than check valves made of other materials, making it a perfect choice for industrial check valves.
