4WE6HB6X/EG24N9K4QM0G24

The 4WE6HB6X/EG24N9K4QM0G24 directional spool valve belongs to the WE Directional Spool Valves series from Bosch Rexroth. It shifts hydraulic flow paths in automation circuits to start, stop, or reverse actuators. An ISO 4401-03-02-0-05 mounting interface lets the valve bolt directly to standard subplates, simplifying manifold layout. The electromagnetic actuation relies on a wet-pin detachable coil marked E; this design allows rapid coil replacement without opening the pressure envelope. Each coil operates at a nominal voltage of 24 V DC and absorbs 30 W, so power supplies can be sized accordingly. Continuous service is supported by a 100 % duty cycle, preventing temperature related downtime during long machine cycles. Electrical termination is handled through a DIN EN 175301-803 connector, providing keyed orientation and strain relief. An IP65 ingress rating protects the enclosure from dust and low-pressure water jets in wash-down areas. The valve may be installed in any position, which grants design flexibility for horizontal or vertical manifolds.

Hydraulic performance is defined by a maximum flow of 80 l/min, permitting medium-capacity circuits to operate without excessive pressure loss. Ports P, A, and B withstand up to 350 bar, while the tank port tolerates 210 bar, so system designers can set relief valves with a comfortable safety margin. A switching frequency of up to 4.2 operations per second allows the spool to follow fast command sequences in servo-controlled loops. A concealed manual override coded N9 is provided; it can be used when electrical power is absent and functions safely up to 50 bar in the tank line. Spool position feedback is available through a QM0 type position switch that signals the rest position; it is powered from the same 24 V DC supply used for the coils, reducing wiring variation. Together, these specifications enable precise, durable, and serviceable control of actuator direction in industrial hydraulic equipment.
