The 4WE6E6X/EG12N9K4/V/62 directional spool valve belongs to the WE Directional Spool Valves series and is built by Bosch Rexroth for hydraulic automation tasks such as actuating cylinders or motors in mobile or industrial equipment. It is energized with a 12 V DC coil voltage so it can be driven directly from low-voltage control systems. A rated current of 2.5 A at that voltage keeps coil heating within limits while delivering full shifting force. The nominal power draw is 30 W, allowing compact power supplies to operate the solenoids continuously because the duty cycle is specified as 100 % ED. Flow enters through an ISO 4401-03-02-0-05 mounting pattern and exits through an NFPA D03 porting pattern, making the valve interchangeable with common subplates. The design supports a maximum flow of 80 l/min, ensuring adequate throughput for medium-size actuators without excessive pressure drop.
The spool symbol is designated E, defining the internal flow paths selected when each solenoid is energized. A maximum operating pressure of 350 bar on ports A, B, and P allows the valve to control high-pressure supply lines, while the return port T is limited to 210 bar to protect tank lines. Sealing elements are made from FKM, giving compatibility with many hydraulic fluids at elevated temperatures. Electrical connection is through a DIN EN 175301-803 K4 plug, and the housing achieves IP65 ingress protection when the plug is installed, protecting the coil from dust and water jets. A concealed manual override identified by code N9 lets maintenance staff shift the spool without power for testing or emergency repositioning. Installation is guided by an ISO 8752-3x8-St locating hole that centers the body on the subplate. Two solenoids bring the total weight to 1.95 kg, which influences manifold support requirements.
