The 4WE6D6X/EG24N9K72L directional spool valve is produced by Bosch Rexroth within the WE Directional Spool Valves series. It shifts hydraulic flow between working lines in automated circuits by means of a solenoid energized at a nominal 24 V DC. The valve conforms to size 6 and provides four ports to interface with pressure, tank, and two actuator lines. Continuous duty flow reaches 80 l/min, while lines a, b, and p can accept pressures up to 350 bar and the tank port withstands 210 bar. The coil draws a rated current of 1.25 A, and the M12 connector assigns Pin 4 for the 24 V supply and Pin 3 for ground to simplify wiring.
The enclosure carries an IP65 rating so the unit resists dust ingress and low-pressure water jets in harsh machine environments. The body can be mounted in any installation position, and system oil must meet ISO 4406 20/18/15 cleanliness to maintain spool accuracy. A manual override is available and may be operated against tank pressure up to 50 bar for commissioning or emergency movement. To protect driver electronics, a 48 V suppression circuit is recommended because the coil can generate switch-off overvoltage peaks up to 500 V. The mean time to dangerous failure is projected at 300 years, providing confidence for long-term service in safety-related machinery.
