The 4WE6HA6X/EG24N9K4QMAG24 directional spool valve is produced by Bosch Rexroth for the WE Directional Spool Valves series and diverts hydraulic flow between ports in automated machinery. It tolerates a maximum operating pressure of 350 bar on the pressure, A, and B lines, while the tank port accepts up to 210 bar so back-pressure does not compromise the seals. The body follows the ISO 4401-03-02-0-05 porting pattern, allowing direct mounting on standard sub-plates. A flow rate capability of 80 l/min supports medium-capacity actuators without excessive pressure loss. The solenoid is energized with 24 V DC and draws 1.25 A; it also withstands 500 V switch-off overvoltage to protect the winding. Thermal endurance is defined by class F insulation and a coil surface limit of 120 °C. A concealed manual override lets technicians shift the spool during power loss, and an IP65 enclosure shields the electrical assembly from dust and water spray.
Electrical connection is handled through a DIN EN 175301-803 type K4 plug that carries three contacts arranged as two power lines plus protective earth. The plug integrates an inductive QM position switch that relays spool status to the controller, and monitoring is dedicated to the a position so each shift is confirmed electronically. Hydraulic fluid must meet ISO 4406 20/18/15 cleanliness to keep the precision-fitted spool from sticking under load. The standardized connector simplifies field service, and the three-pin layout leaves room for cable strain relief in confined manifolds. By combining feedback through the integrated switch with the contamination control requirement, the valve provides reliable on-off flow control for presses, test rigs, and material-handling lines where consistent response and diagnostic data are essential.
