The 4WE6D6X/EG125N9K4QMAG24 valve is manufactured by Bosch Rexroth in the WE Directional Spool Valves series to route pressurized fluid in automated hydraulic machinery. With a nominal size of NG6, the unit fits compact manifolds used on small to mid-range cylinders and motors. The ISO 4401-03-02-0-05 porting pattern aligns with standard subplate layouts, reducing installation effort. Two discrete spool positions provide simple bidirectional flow control for extend and retract functions. The valve passes up to 80 l/min, supporting rapid actuator movement at moderate flow demand. Operating pressure is limited to 350 bar at the P, A, and B ports, while the T port is protected to 210 bar to safeguard return plumbing. NBR seals contain the hydraulic medium, and an IP65 enclosure rating shields internal components from dust ingress and water spray encountered in plant environments.
Continuous service is possible because the magnet coil is rated for a 100 % ED duty cycle. It runs on 125 V DC, and performance remains stable when supply varies within a ±10 % band. The assembly draws 30 W under nominal conditions, allowing integration with low-capacity control power supplies. Electrical connection is made through a DIN EN 175301-803 K4 plug that enables fast replacement during maintenance. A concealed manual override identified as N9 lets maintenance staff shift the spool mechanically for setup or fault recovery. Spool position is monitored by an inductive QM sensor, and the switch receives its power from a dedicated 24 V DC feed to keep control circuits isolated from coil voltage.
