Check valves are used to prevent medium backflow by automatically opening and closing of the discs. Check valves are mainly used in one-way pipelines, allowing only one direction of media flow to prevent accidents.

Check valves can be divided into four types according to the movement mode of the disc: Swing Check Valve, Lift Check Valve, Nozzle Check Valve, Dual Plate Check Valve

  • Swing Check Valve H44
  • Pressure Seal Check Valve H44
  • Dual Plate check valve H76
  • Nozzle Check Valve GLH41
  • Design Features
