The 4WRA6W1-07-2X/G24N9K4/V proportional directional valve is produced by Bosch Rexroth within the 4WRA Proportional Directional Valves series. It meters hydraulic flow in automated machinery that require controlled actuator positioning. A 24 V DC supply powers the magnetic actuation, integrating with common control systems. The valve is built to size 6 and follows the ISO 4401-03-02-0-05 porting pattern for compatibility with standard manifolds. Subplate mounting allows quick replacement without disturbing hard plumbing. Nominal flow is 7 l/min at a differential pressure of 5 bar per metering edge, while maximum flow reaches 42 l/min when higher throughput is needed. A concealed manual override lets maintenance personnel shift the element mechanically during commissioning or troubleshooting. FKM seals are fitted to maintain leakage control with typical hydraulic fluids.
The housing carries an IP65 protection class so dust ingress and water jets do not jeopardize operation. The hydraulic circuit should maintain cleanliness of ISO 4406 (c) 20/18/15 to preserve internal surfaces. Operating pressure capability is 350 bar on pressure and work ports a, b, and p, with 210 bar permitted on the tank port t, covering a broad range of medium-pressure systems. Viscosity up to 380 mm²/s is accepted, which supports use of heavier oils at low temperatures. Continuous service accommodates hydraulic fluid up to +70 °C, and surrounding ambient temperatures up to +80 °C, permitting installation near warm equipment. The assembled unit weighs 2.0 kg, making manual handling straightforward during installation or replacement. These parameters establish reliable performance for closed-loop hydraulic automation that depends on precise, electrically modulated flow.
