The 4WRPE6E32SJ-2X/G24K0/A1M proportional valve is produced by Bosch Rexroth within the 4WRP Solenoid Valves series. It meters hydraulic flow to actuators in automated machinery by shifting a spool in response to an electrical reference. The unit is built with nominal size 6 to fit compact manifolds, and it passes a nominal flow of 32 l/min at rated differential pressure. A progressive flow characteristic gives finer resolution near the neutral position, while three switching positions allow centered blocking or two metering directions during operation. The spool carries symbol E, and overlap compensation code J minimizes dead band. Motion commands are introduced as a ±10 V analog signal, and the solenoid coils are energized from a 24 V DC supply.
Installation uses subplate mounting that matches the ISO 4401-03-02-0-94 porting pattern, secured with M5 bolts for consistent clamping force. The K0 unit plug defined by DIN 43563-AM6 provides the electrical interface and contains six power and signal contacts plus a protective earth connection. System pressure limits reach 315 bar on ports P, A, and B, while the tank port tolerates up to 200 bar, permitting use in high-pressure circuits. The valve body weighs 3.9 kg, supporting rigid attachment without extensive bracketing. These mechanical, hydraulic, and connection features integrate the 4WRP device into control loops that require proportional flow control under demanding industrial pressures.
