The 4WE6HA6X/EG24N9K72L/A12/62 directional spool valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and is used to shift hydraulic flow paths in automated circuits. A nominal size of 6 allows the valve to fit compact manifolds while still handling system demands. Its porting pattern follows ISO 4401-03-02-0-05, so mounting surfaces are standardized for interchangeable service modules. The pressure ports P, A, and B can be loaded up to 350 bar, enabling the device to work in high-pressure actuation loops. A maximum flow of 80 l/min keeps actuators supplied without excessive pressure drop. Switching damping coded A12 moderates spool movement to reduce hydraulic shock when directions change. Cleanliness in the circuit must reach ISO 4406 20/18/15 to protect the precision spool lands from abrasion. A locating hole for an ISO 8752-3×8 pin secures the body against movement in the manifold, and a 100 % ED duty rating lets the solenoid remain energized continuously during long cycles.
The solenoid is designed for a nominal voltage of 24 V DC and draws 1.25 A at that rating, resulting in a coil power of 30 W for reliable actuation force. Voltage may fluctuate within ±10 %, permitting operation on supplies that are not tightly regulated. Electrical hookup is made through an M12×1 four-pin connector marked K72L, which simplifies wiring in modular machine harnesses. The connector assembly achieves IP65 protection, preventing dust ingress and low-pressure water jets during wash-down. A maximum switching frequency of 4.2 cycles per second supports rapid control loops without overheating the coil. Tank port T can withstand 210 bar in direct-current operation, so back-pressure from downstream throttling does not compromise the housing. Together these electrical and hydraulic characteristics allow the valve to deliver dependable, high-speed direction control in industrial mobile or stationary equipment.
