The 4WRA10W60-2X/G24N9K4/V-674 proportional directional valve is built by Bosch Rexroth and belongs to the 4WRA Proportional Directional Valves series. It meters hydraulic flow to actuators in automation circuits and uses a W spool to shift fluid paths according to control signals. The valve operates on a 24 V DC supply and draws current through a coil with a resistance of 2 Ω at 20 °C. Continuous service is supported by a 100 percent duty cycle, so the solenoid may remain energized without cooling pauses. Electrical connection is made through a plug conforming to DIN EN 175301-803, and the housing carries an IP65 rating to block dust and water during industrial operation. The unit is sized NG10, giving port dimensions compatible with manifold cavities for nominal size 10 hardware, and it withstands system pressures up to 315 bar on the pressure inlet.
The valve handles a nominal flow of 60 l/min at a 10 bar pressure drop and can pass up to 75 l/min when flow demand peaks. Port T is limited to 210 bar to protect return-line components. Acceptable hydraulic media have viscosities from 20 to 380 mm²/s and temperatures between −20 °C and +80 °C, allowing use with common mineral oils over a broad operating envelope. Internal elastomers are FKM seals that tolerate high temperature and synthetic fluids while maintaining leakage integrity. Cleanliness requirements are ISO 4406 (c) 20/18/15, so upstream filtration must keep particulate counts within this level for reliable spool movement. The assembly weighs 6.6 kg, which supports rigid mounting on standard subplates without additional bracing.
