The 4WRPE6W32SJ-2X/G24K0/A1M valve is manufactured by Bosch Rexroth for the 4WRP Solenoid Valves series. It meters hydraulic flow in closed-loop automation systems where proportional control of actuator speed or force is required. Actuation is provided by a proportional solenoid with on-board electronics, converting control signals into precise spool movement. The electronics accept a ±10 V command value input, and internal circuits are powered by a 24 V DC supply voltage. Nominal size 6 defines the interface dimensions, while the spool is the W type, enabling bidirectional throttling around the neutral point. A progressive flow characteristic lets the user achieve fine resolution at low openings and higher flow at large openings. With a nominal flow of 32 l/min at a 5 bar pressure drop, the unit handles medium-capacity circuits. The step response to a full-scale command is 20 ms, supporting fast loop tuning. Mounting follows the ISO 4401-03-02-0-94 porting pattern for interchangeability with standard subplates.
Electrical connection is made through a 6P+PE connector conforming to DIN 43563-AM6, which carries power, analog input, and protective earth in a sealed plug; the keyed housing prevents misalignment during service. The valve sustains working pressures up to 315 bar in ports p, a, and b, while port T is limited to 200 bar to protect return lines, so it can be placed directly on pump discharge manifolds. Maximum hysteresis is 0.3 %, reducing steady-state position error during directional changes, and the inversion range is limited to 0.2 %, minimizing deadband around the null point for smooth reversal. Leakage per metering edge is 80 cm³/min at 100 bar, a value that simplifies heat management in closed circuits by limiting internal flow losses. Total weight is 3.9 kg, allowing direct manifold mounting without additional support brackets and easing handling during maintenance.
