4WRA6W15-2X/G24N9K4/V-589

The 4WRA6W15-2X/G24N9K4/V-589 proportional directional valve is manufactured by Bosch Rexroth within the 4WRA Proportional Directional Valves series. It directs flow to hydraulic actuators according to the solenoid command and supports precise motion control in automated machinery. A nominal size of 6 defines the interface dimensions so the valve fits standard size-6 subplates. The nominal flow of 15 l/min establishes baseline capacity for continuous operation, while a maximum flow of 42 l/min allows short demand peaks without exceeding design limits. The unit handles operating pressures up to 350 bar on ports A, B, and P, enabling use in high-pressure circuits. Its 24 VDC supply voltage powers the solenoid that positions the spool proportionally to the input signal. Subplate mounting is the connection method, and the ISO 4401-03-02-0-05 porting pattern fixes the hole layout to simplify manifold design. An IP65 protection class safeguards the enclosure against dust ingress and water jets, and the assembly weighs 2.0 kg to permit easy handling during installation.

For return lines the T port tolerates pressures up to 210 bar, so back-pressure in counterbalance circuits will not damage the housing. Hydraulic fluid may reach 70 °C, and the spool body itself may run up to a surface temperature of 150 °C without loss of function. The design accepts oils with viscosities up to 380 mm²/s, maintaining proportional control even with high-viscosity fluids at cold start. FKM seals are fitted to resist heat and aggressive additives, ensuring leakage control across the stated temperature range. A concealed manual override lets maintenance personnel shift the spool mechanically during commissioning without exposing the mechanism to accidental actuation. The cleanliness requirement of ISO 4406 20/18/15 protects the precision edges from contamination-induced wear, preserving metering accuracy in long-term service.
