Proportional and Servo Valves

Hydraulic Pressure Relief

Image Desc
Improving Machine and Manufacturing Productivity

Proportional pressure relief valves limit the pressure in a hydraulic circuit and allow this set limit to be adjusted by electronic control. While relieving pressure, excess flow is returned to a hydraulic reservoir tank, to improve machine efficiency and manufacturing productivity. Rexroth has developed multiple direct and pilot operated designs provide a wide range of hydraulic flow capacity for any relief circuit.
