Application
▪ Wafer Type Non-Return Check Valves (the double flap check valve) is mainly composed of valve body, valve disc, valve stem, spring and other important parts and components. It adopts a thin and lightweight design. As the closing stroke between the discs is shortened and the spring action can accelerate the closing effect, it can reduce water hammer and water hammer sound.
▪ The valve is mainly used in water supply systems, high buildings and industrial areas. As the distance between the surfaces is shorter than that of general check valves, it is most convenient for the places with limited installation space.
▪ Test pressure:
Shell Test Pressure 1.5 x PN
Seat Test Pressure 1.1 x PN
