The 4WE6X5A6X/EG24K4 directional spool valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and is used to switch or block hydraulic flow in automated machinery. It is built in size 6, allowing direct mounting on NG6 subplates configured to the ISO 4401-03-02-0-05 porting pattern. A maximum operating pressure of 350 bar lets the valve control high-pressure circuits, while a maximum flow of 80 l/min keeps pressure drops low during rapid actuator movements. The return passage tolerates up to 210 bar at port T, so back-pressure in tank lines remains within safe limits. Because the installation position can be any orientation, designers have flexibility when arranging manifold layouts. Correct assembly requires tightening the mounting bolts to 7 Nm, and a clamping length of 42 mm ensures the body seats evenly on the subplate.
The solenoid coil operates on 24 V DC and draws a rated current of 1.25 A, providing reliable shifting force with standard control power supplies. Electrical connection is through a DIN EN 175301-803 form K4 plug, which simplifies field wiring and supports quick coil replacement. An IP65 protection class shields the coil and terminals against dust and water jets, enabling use in typical factory wash-down zones. The valve must be supplied with oil that meets ISO 4406 cleanliness class 20/18/15 to prevent wear of the precision spool lands. It weighs 1.95 kg, so single-operator installation is practical even in overhead manifolds. A mean time to dangerous failure of 300 years contributes to high safety integrity for equipment that demands long service life without frequent component replacement.
