The 4WE6J73-6X/EG24N9K72L/A12V/62 AN valve belongs to the WE Directional Spool Valves series produced by Bosch Rexroth to route hydraulic flow in automated machinery. It is built around nominal size 6 ports, so it fits compact manifolds while still passing up to 80 l/min. A porting pattern that follows ANSI B93.9 lets the body mount on standard sub-plates, and an ISO 8752-3x8-St locating pin keeps the channels correctly aligned during installation. FKM sealing is used to tolerate common hydraulic oils and elevated temperatures. The pressure limit reaches 350 bar on P, A, and B, giving the unit headroom for high-pressure supply lines, while the T return port is rated to 210 bar to protect the tank circuit. To keep internal clearances working, the hydraulic medium must meet ISO 4406 20/18/15 cleanliness. Together these characteristics establish a compact, high-pressure valve suited for precise flow direction in servo loops and mobile work modules.
The solenoid section is driven from a 24 V DC supply, and the coil draws a rated current of 1.25 A, resulting in a nominal power consumption of 30 W. A 100 % duty cycle allows continuous energization without exceeding thermal limits, while the coil surface may reach 120 °C under worst-case loading and still remain within design margins. Electrical connection is made through an M12×1 four-pin K72L plug, providing quick disconnect and keyed polarity. The assembly is sealed to IP65, so dust ingress and low-pressure water jets do not affect operation when the connector is properly mated. A switching frequency of 1 Hz supports one complete shift per second, which is typical for proportional positioning of hydraulic actuators. These electrical data, combined with the hydraulic ratings outlined earlier, define a valve that can cycle continuously in factory or mobile installations that rely on stable 24-volt control networks.
