The 4WRPE6Q5-32M-2X/G24K0/A1M-836 proportional solenoid valve is produced by Bosch Rexroth for the 4WRP Solenoid Valves series. It meters hydraulic flow in closed-loop automation circuits where precise pressure and speed control are required. The valve is built in nominal size NG6, allowing it to fit compact manifolds and save space in small power units. A standard ISO 4401-03-02-0-94 mounting interface supports direct installation on subplates without custom drilling. During operation it handles line pressures up to 315 bar on ports P, A, and B, while the tank port tolerates 200 bar, so it suits medium-pressure systems. Each metering notch passes 32 l/min at a 5 bar differential to maintain stable actuator velocity. A ±10 V command input accepts signals from servo controllers, and the 100 kΩ input impedance minimizes loading of electronic outputs. The electronics require a 24 V DC supply and deliver a typical 20 ms response to a full-scale step, contributing to fast cylinder positioning.
Environmental and service features support reliable field use. An IP65 degree of protection shields the enclosure from dust and low-pressure water jets, making cabinet sealing unnecessary. Electrical power and feedback are routed through a 6+PE plug conforming to DIN 43563-AM6, which simplifies maintenance because the connector can be replaced without rewiring the harness. The valve body endures 25 g vibration along all three axes for 24 hours, allowing installation on mobile or high-dynamic machinery. NBR seals resist mineral oil and maintain leakage control across the full pressure range. Cleanliness requirements match ISO 4406 (c) 18/16/13, so standard filtration prevents abrasive wear of the metering edges. The unit weighs 3.9 kg, light enough for mounting directly on small manifolds without extra support.
