Hydraulic Check Valve is an automatic hydraulically controlled valve that prevents backflow in the system instead of a check valve at the pump outlets. When the outlet pressure value exceeds the inlet pressure value, the valve closes itself without creating a pulse. When the inlet pressure value exceeds the outlet pressure value, the valve opens slowly. Thus, it prevents the pressure fluctuation that occurs at the start of the pump.

  • Easy operation and maintenance with its simple structure
  • Lower costs
  • Working in a wide pressure range
  • Perfect modulation even at low flow rates
  • Shockless opening – closing with flexible diaphragm
  • Complete sealing with reinforced diaphragm and inner spring
  • Epoxy – Long life with polyester coating
  • Wide control application area with the use of different pilot valves
  • Ability to work in horizontal and vertical positions in application areas
