4WRA6W07-2X/G24K4/V

The 4WRA6W07-2X/G24K4/V valve is part of the 4WRA Proportional Directional Valves series produced by Bosch Rexroth for closed loop hydraulic automation. The unit meters fluid flow to actuators in response to a 24 VDC command, making the solenoid compatible with standard control electronics. It withstands 350 bar on pressure ports A, B, and P, so it can be placed in high-pressure circuits without additional reducers. A nominal flow of 7 l/min at a 5 bar drop per edge helps designers predict spool behavior during fine positioning tasks. The ISO 4401-03-02-0-05 porting pattern and subplate mounting style allow quick replacement on manifolds that follow the same interface. An IP65 enclosure prevents dust ingress and water jets from affecting the coil, while the K4 two-pole plus protective earth connector provides a secure electrical link. System oil must meet cleanliness class ISO 4406 (c) 20/18/15 to avoid spool binding, and the valve’s 2.0 kg mass permits easy handling during assembly.

During operation the valve can pass up to 42 l/min, enabling rapid cylinder movements when higher flow is demanded. The tank port tolerates 210 bar, so back-pressure fluctuations are acceptable in systems with long return lines. Each port bore measures 8 mm to match standard subplate passages and maintain predictable pressure drops. Installation requires four M5 × 50 - 10.9 screws tightened to 7 Nm, a setting that secures the housing without distorting the manifold face seal. FKM seals resist common hydraulic fluids and temperatures up to 150 °C, preventing leakage during extended high-temperature duty cycles. This temperature limit also defines the maximum permissible surface temperature of the coil and body, letting the valve sit near heat sources without exceeding component ratings. These mechanical, hydraulic, and thermal limits combine to deliver stable proportional control in presses, injection machines, and other automated equipment.
