The 4WRPE10V80M-2X/G24K0/A1M-837 proportional valve is produced by Bosch Rexroth within the 4WRP Solenoid Valves series. It meters oil flow to actuators in closed-loop hydraulic drives where precise speed and position control are required. The valve is built in nominal size 10, so it matches medium-frame subplates. Installation follows the ISO 4401-05-04-0-94 pattern which simplifies interchange with standard manifolds. Under a differential pressure of 5 bar it provides a nominal flow of 80 l/min, enabling rapid cylinder or motor movement. Ports P, A and B withstand pressures up to 315 bar, while the tank port is limited to 200 bar to protect return lines. A symmetrical ±10 V command serves as the input signal for the integrated electronics. Step changes of that command reach steady state in 40 ms, supporting tight control loops, and electrical hysteresis is held to 0.3 percent or lower to maintain repeatability.
The solenoid assembly is powered from a 24 V DC source, with proper operation maintained between 21 V DC and 40 V DC so mobile or industrial supplies with minor fluctuations remain acceptable. Coil and amplifier draw 60 VA, permitting sizing of power supplies and heat dissipation. Connection is made through a 6P+PE plug conforming to DIN 43563, and a time-lag 2.5 A external fuse is specified to clear faults without nuisance trips. The housing carries an IP65 rating when the matching connector is fitted, preventing dust ingress and water jets during machine wash-down. Overall mass is 8.3 kg, which must be supported by the subplate or manifold. These electrical and mechanical features allow the valve to integrate into servo-hydraulic automation systems that demand consistent response, safe wiring, and environmental resilience.
