4WE6J6X/EG96NK4/B12

The 4WE6J6X/EG96NK4/B12 valve is a member of the WE Directional Spool Valves series manufactured by Bosch Rexroth for hydraulic automation tasks that require controlled flow direction in pressurized circuits. It is energized by a 96 V DC coil, and the allowable voltage variation of ±10 percent protects performance when supply levels fluctuate. The coil is rated at 30 W so power consumption stays modest while shifting the spool. A continuous duty rating of 100 percent ED lets the solenoid remain energized indefinitely without cooling pauses, supporting long holding cycles in machine tools. The design supports up to 4.2 switching actions per second, enabling rapid directional changes where high cycling rates are needed. When open, the hydraulic channels can pass up to 80 L per minute, which matches medium-size actuator demands. The pressure limit on ports A, B, and P is 350 bar, allowing the valve to handle high-pressure supply lines. A 1.2 mm throttle insert in port P smooths the flow and reduces pressure shocks during shifts.

Port T can be exposed to 210 bar, so back-pressure in the tank line does not exceed the mechanical limits of the housing. The maximum coil surface temperature is 120 °C, which defines the thermal envelope for continuous operation in heated manifolds. Protection class IP65 shields the electrical section against dust and low-pressure water jets, making the valve suitable for installation on exposed machinery frames. An F insulation class is applied to the winding, permitting higher operating temperatures before dielectric breakdown occurs. The mounting face follows the ISO 4401-03-02-0-05 porting pattern, allowing direct interchange with other D03 size components, while the subplate interface matches NFPA T3.5.1 R2-2002 D03 so North American manifolds can be used without adapters. With two solenoids installed the assembly weighs 1.95 kg, light enough for stacking several valves on a common bar manifold without stressing support brackets.
