The 4WE6X7-6X/EG24N9K4QMBG24 directional spool valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and routes hydraulic flow in automated machinery. It is built in nominal size 6 so it occupies minimal manifold space while still providing adequate passage area. The valve bolts to subplates using the ISO 4401-03-02-0-05 interface, giving compatibility with standard CETOP 03 layouts. Actuation is delivered by a 24 V DC wet-pin solenoid that consumes 30 W at rated conditions. A 100 % ED duty cycle lets the coil remain energized continuously, and its ±10 % voltage tolerance keeps performance stable during supply fluctuations. Electrical wiring uses a K4 connector in accordance with DIN EN 175301-803, and the enclosure achieves IP65 to prevent dust ingress and water spray. The single-solenoid assembly weighs 1.45 kg, allowing easy installation without lifting equipment.
Flow capacity reaches 80 l/min in direct-current operation, supporting medium-sized actuators. Pressures at ports P, A, and B may rise to 350 bar, so the unit suits high-pressure circuits, while the tank port is limited to 210 bar to protect return plumbing. A concealed N9 manual override enables local switching when power is absent without exposing protruding levers. The integrated QMBG24 position switch observes the “b” spool position and returns a feedback signal to the control system. Maximum switching frequency is 4.2 cycles per second, which sustains rapid directional changes in repetitive sequences.
