4WE6J6X/EG110N4K4 CSA

The 4WE6J6X/EG110N4K4 CSA directional spool valve is part of the WE Directional Spool Valves series produced by Bosch Rexroth for hydraulic automation where rapid on-off control of flow is required. The unit is built in nominal size 6, so it fits NG6 manifolds and compact power packs. It bolts to subplates that follow the ISO 4401-03-02-0-05 interface, while the equivalent NFPA code T3.5.1 R2-2002 D03 allows the same footprint in North-American systems. During operation the P, A, and B ports can be pressurized up to 350 bar, and the T port withstands 210 bar, enabling the valve to handle high-pressure circuits without separate relief devices. With a maximum direct-current flow capacity of 80 L/min, it supports medium-size actuators without excessive pressure drop. Continuous service is permitted because the duty cycle is 100 percent (S1). The housing carries an IP65 rating, sealing the coil and terminals against dust ingress and water jets often encountered near hydraulic power units. The specified fluid cleanliness of ISO 4406 class 20/18/15 limits particulate contamination to protect the precision spool and reduce wear.

The electromagnetic actuator is designed for a 110 V DC supply and draws 0.25 A, which results in a nominal coil power of 30 W during steady energization. Control cabinets may use unregulated supplies because the coil accepts a ±10 percent voltage swing without loss of switching reliability. Electrical connection is made through a K4 plug conforming to DIN EN 175301-803, simplifying field wiring with standard cord sets. When electrical power is absent, operators can shift the spool with a lockable N4 manual override, allowing safe commissioning or emergency positioning. The solenoid can reverse up to 4.2 cycles per second under direct current, supporting moderately fast machine sequences. These electrical characteristics combine with the hydraulic ratings cited earlier to deliver consistent performance in automated presses, material handling tables, and other continuous-duty installations.
