The 4WRPE6W08SJ-2X/G24K0/A1M valve belongs to the 4WRP Solenoid Valves series and is produced by Bosch Rexroth for proportional flow control in hydraulic automation systems. It has a nominal size of 6 and installs on an ISO 4401-03-02-0-05 interface. A 24 V DC solenoid actuates the spool while an external ±10 V command input sets the desired position. The metering edges follow a progressive flow characteristic, enabling small command changes to create gradual flow variation. An overlap jump limited to 5 % of the command range reduces deadband at center. Under a 5 bar pressure drop the valve passes a rated 8 l/min, whereas leakage between port A and the tank at zero command is 0.8 l/min. The hydraulic fluid must meet ISO 4406 cleanliness class 18/16/13 to maintain the sliding accuracy of the assembly.
The valve supports a maximum flow of 80 l/min when fully stroked. Working pressure on ports P, A, and B may reach 350 bar, and the tank port can accept up to 200 bar return pressure without affecting stability. Continuous service is allowed with fluid temperatures up to 70 °C, and NBR seals maintain elasticity under these conditions. A housing protection class of IP65 safeguards the coil and connector against dust and low-pressure water jets. The design handles viscosities up to 800 mm²/s, so the assembly functions during cold starts or with heavy oils. These characteristics give the 4WRPE6W08SJ-2X/G24K0/A1M predictable flow response and pressure capability in servo-hydraulic circuits.
