The 4WRA6EA15-2X/G24N9K4/V proportional directional valve is built by Bosch Rexroth as part of the 4WRA Proportional Directional Valves series. It modulates flow and direction in hydraulic automation circuits. With a nominal size of 6, the valve fits compact manifolds while providing a nominal flow of 15 l/min at a pressure drop of 5 bar per metering edge. Its spool marked EA establishes the switching logic required for cylinder control. A maximum flow rating of 42 l/min extends the usable range when higher actuator speeds are needed. System pressure can be applied to ports A, B, and P up to 350 bar, enabling operation in high-pressure industrial systems. Subplate mounting in accordance with ISO 4401-03-02-0-05 simplifies installation on standardized bases. For local testing, a concealed N9 manual override allows the spool to be shifted without energizing the solenoid.
In service, return flow through port T is limited to 210 bar, which prevents back-pressure from damaging the housing. The enclosure achieves IP65 protection, so dust ingress and water jets cannot reach the internal solenoid. Electrical connection is made through a K4 plug with two power contacts and a protective earth, supporting straightforward wiring in control cabinets. Sealing elements are produced from FKM, giving chemical resistance to common hydraulic fluids. The valve may be installed in any orientation, allowing flexible layout inside tight power units. A surface temperature limit of 150 °C defines the thermal boundary for continuous duty near hot machinery. Mean time to dangerous failure is rated at 150 years, supporting safety calculations in performance level designs. The assembly weighs 2.0 kg, light enough for quick replacement during maintenance.
