4WE6D6X/OFEW230NK4/62

The 4WE6D6X/OFEW230NK4/62 valve is manufactured by Bosch Rexroth and belongs to the WE Directional Spool Valves series. Designed to route pressurized oil between actuator ports in hydraulic automation, it operates on a coil voltage of 230 V at 50 or 60 Hz, allowing direct connection to standard industrial supplies. A switch-on power requirement of 220 VA ensures rapid magnetic force development so the spool shifts promptly under load. After actuation, the coil retains position with 50 VA holding power, reducing energy consumption during prolonged energization. The duty cycle is rated at 100 percent, which permits continuous operation without forced cooling intervals. Insulation class H windings withstand elevated internal temperatures generated by frequent cycling. Electrical interface is provided by a K4 connector to DIN EN 175301-803, enabling quick plug-in wiring and reliable sealing. The valve is built in nominal size 6 to fit compact manifolds, and its ports adhere to ISO 4401-03-02-0-05 for interchangeability with other size-6 components.

The enclosure achieves an IP65 rating, protecting the solenoid from dust ingress and low-pressure water jets encountered in machinery wash-down zones. Coil surface temperature is limited to 120 °C to preserve winding integrity during sustained duty. Hydraulic capacity reaches 60 l/min, giving adequate flow for medium-power cylinders and motors. Maximum operating pressure at ports P, A, and B is 350 bar, enabling use in high-pressure circuits, while the tank port tolerates 160 bar to accommodate backpressure without leakage. Integrated suppression limits switch-off overvoltage to 500 V, guarding connected control relays and drivers. A maximum switching frequency of two cycles per second supports fast directional changes demanded by servo-controlled stages. With two solenoids fitted the assembly weighs 1.95 kg, light enough for direct manifold mounting without additional supports.
