Bosch Rexroth Hydraulic Proportional Valve

The Bosch Rexroth Hydraulic Proportional Valve is a high-performance electro-hydraulic control element that enables precise, continuously variable regulation of hydraulic flow, pressure, or direction. By using a proportional solenoid (often with integrated electronics / on-board amplifier), the valve converts an electrical input signal into a corresponding hydraulic output — enabling smooth, accurate control of actuators (cylinders or motors) in industrial and mobile hydraulic systems. Thanks to robust construction and tested reliability, Rexroth’s proportional valves are widely used in automation, mobile machinery, test rigs, and industrial hydraulics.
