The 4WE6GA6X/OFEG12N9K4/T06ZV is produced by Bosch Rexroth within the WE Directional Spool Valves series for routing pressure and return flow in hydraulic automation loops. It uses a 12 V DC solenoid coil so the valve can be driven directly from mobile power networks. The electromagnetic circuit draws a rated current of 2.5 A, and the nominal power demand is 30 W, which helps limit temperature rise in enclosures. Because the duty cycle is 100 % ED, the coil may stay energized continuously without service interruption. A voltage tolerance of ±10 % guards against nuisance drop-outs caused by supply fluctuation. Electrical termination is provided by the K4 connector defined in DIN EN 175301-803, and when this plug is fitted the enclosure achieves IP65 protection against dust ingress and water jets. With both solenoids mounted, the assembly weighs 1.95 kg, allowing a single technician to install the unit onto a manifold plate.
The valve handles a maximum flow of 80 l/min, enabling responsive actuation of medium-size cylinders and motors. Ports P, A, and B withstand operating pressures up to 350 bar, while the tank port is rated for 210 bar, so back-pressure devices can be used without exceeding component limits. FKM seals resist mineral oil and elevated temperature to maintain leakage control over long service intervals. Internal spool play is held to the T06 minimum, reducing bypass leakage when the valve is centered. A 22 mm clamping length secures each coil to the tube to preserve magnetic alignment during vibration. For manual positioning the concealed N9 override can be depressed with a tool, protecting it from accidental activation when the enclosure is open. The interface follows the ISO 4401-03-02-0-05 pattern, allowing direct mounting on standard CETOP 3 base plates used throughout machine automation.
