4WE6D6X/OFEG48NXEZ2/V

The 4WE6D6X/OFEG48NXEZ2/V directional valve is manufactured by Bosch Rexroth within the WE Directional Spool Valves series. It directs pressurized oil to selected actuator ports so automated hydraulic systems can extend, retract, or hold loads on demand. The valve bolts to subplates that match the NFPA T3.5.1 D03 mounting interface, which simplifies field replacement. Its porting pattern follows ISO 4401-03-02-0-05 to maintain channel alignment with standard manifolds. Ports P, A, and B are rated for 350 bar, enabling the unit to manage high working pressures, while the T port is restricted to 210 bar to preserve return-line integrity. A maximum flow of 80 l/min supports medium-sized cylinders without excessive pressure drop. FKM seal material resists mineral oils and elevated temperature, reducing leakage over time. System fluid must remain cleaner than ISO 4406 class 20/18/15 so the spool surfaces are not damaged by particulate contamination.

The electromagnetic actuation package is specified for a 48 V DC coil, allowing the valve to run from common low-voltage supplies on mobile or industrial equipment. The coil draws 0.66 A at the nominal 30 W power level, so panel designers can size conductors and fuses accurately. A voltage tolerance of ±10 % keeps the magnetic force within range during supply fluctuations. Continuous energization is possible because the duty cycle is 100 % ED, eliminating the need for cool-down intervals. Coil surface temperature may reach 120 °C before derating is required, providing a clear thermal limit for enclosure ventilation planning. When the driver circuit switches off, overvoltage is limited to 500 V to prevent insulation breakdown. The solenoid can shift the spool up to 4.2 times per second, defining the maximum control frequency for rapid cycling applications. These electrical characteristics ensure predictable response when the valve is integrated into closed-loop hydraulic automation.
