    Check Valve

    DIN ANSI UPVC CPVC PPH PVDF Wafer Check Valve Manufacture

    Products Features:

    1)Short face-to-face length and easy installation.

    2)High corrosion resistance, Lightweight and cost-effective.

    3)UPVC, CPVC wafer check valve fully open angle is about 40°

    4)Due to the small inner diameter of PPH flanges, to obtain a larger opening angle, it is necessary to chamfer the flange or add a connection plate between the flange and the valve.

      What is advantage of wafer check valve?

      Wafer check valve has short valve structure length, small size and light weight. fast valve closing, low water hammer pressure, smooth flow path, low fluid resistance. horizontal pipeline or vertical pipeline can be used. It is easy to install, sensitive action, good sealing performance, short valve stroke, small impact of the valve, simple structure, beautiful shape, long service life, high reliability. It prevent the medium backflow / reverse flow, automatic control of the opening and closing and so on.
      Wafer check valve is mainly used in petrochemical, iron and steel metallurgy, electric power and other industrial, urban and high-rise building water supply and drainage network. Because the structure length of the clamp connection check valve is shorter than the traditional flange connection check valve. It is the most suitable for the places with installation space limitation.

      What should be pay attention to when install wafer check valve?

      1. It is not allowed to install the valve at the pump flange interface, and it is recommended to install the valve at least 10 times the length of the nominal diameter (DN) 2 meters outside the stabilization zone. 
      2. When installing the valve, it is recommended to use a flat gasket to determine the sealing.   
      3. Pipes with a wall thickness of more than 10 bar are not allowed. 4.   
      4. Suitable for horizontal or vertical installation, vertical installation only allows the fluid direction upwards.   
      5. Install the valve between the flanges (axis alignment) and install the recommended torque to tighten both flanges.
