4WRA6E30-2X/G24N9K4/V-589

The 4WRA6E30-2X/G24N9K4/V-589 proportional directional valve is built by Bosch Rexroth as part of the 4WRA Proportional Directional Valves series and is used to meter and switch hydraulic flow in automated systems. Its solenoid operates on a 24 VDC supply so the valve can be driven directly from common machine control voltages. The internal spool is arranged in a 4/3-way “E” pattern, giving two controlled flow paths and a centered neutral position for bidirectional cylinder control. A size 6 (NG6) envelope allows the valve to fit compact manifolds without sacrificing performance. The porting pattern follows ISO 4401-03-02-0-05, ensuring interchangeability with standard subplates. Because the unit is designed for subplate mounting, removal or replacement can be done without disturbing pipework. At a differential pressure of 5 bar per edge the nominal flow is 26 l/min, which defines the reference metering characteristic for system sizing. The passage can accommodate up to 42 l/min so short-term peak demands are handled without excessive pressure loss. Working ports A, B, and P are rated to 350 bar, allowing the valve to be installed in high-pressure circuits found in presses or injection machines.

The return port T is limited to 210 bar so designers must keep back-pressure within this value to protect the housing. FKM seals are fitted to resist mineral oil and elevated temperature exposure common in industrial power units. Hydraulic fluid may reach 70 °C without degrading valve response, maintaining consistent spool positioning under load. An ambient temperature capability of 80 °C lets the valve function in hot machine enclosures. The enclosure is rated IP65, which guards the electrical parts against dust ingress and low-pressure water jets. A concealed manual override permits local actuation during commissioning or power loss while preventing accidental operation. Circuit oil must be filtered to ISO 4406 class 20/18/15 to keep the precision metering edges free from contamination. A mass of 2.0 kg makes handling and installation straightforward for a single technician.
