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
