DBW Pilot Operated Pressure Relief Valve

DBW Pilot Operated Pressure Relief Valve
Product Details

Pilot operated pressure relief valve uses for controlling the system pressure, keeping system pressure in a normal level in order to protect each actuator operation, especially the power actuation like hydraulic motors, hydraulics pumps.

Finotek DBW series of pilot operated pressure relief valve is designed by two parts, the combination of parts of main valve as basic and pilot operated pressure direct relief valve enable to minimize valve pressure adjusting torque force more than by only a direct relief valve, its largely developing the valve characteristics of opening and closing speed.
