Product Details

Carbon Steel Wafer Dual Plate Check Valve ( H76 )

      The type H76 type check valve consists of valve body, valve clack, valve stem and spring, etc., and is connected with the clamp. Due to the short closing stroke of the valve clack and the spring loading, the water hammer phenomenon can be significantly reduced. The valve is mainly suitable for water supply and drainage pipe of city, industry and high-rise building. As the length of the structure is shorter than that of the general check valve, the place where the installation space is limited is most applicable.
