The 4WE6D73-6X/EG24N9K72L/A12/62 valve is manufactured by Bosch Rexroth for the WE Directional Spool Valves series and directs hydraulic flow in automation systems. A size 6 housing fits standard CETOP 03 manifolds for compact circuit layouts. The D73 spool symbol defines the land pattern that shifts oil paths inside the body, and the A12 smooth-switching design minimizes pressure spikes during transition. Four ports give bidirectional control of a cylinder, while the ISO 4401-03-02-0-05 porting pattern aligns the unit on common subplates. Continuous flow is limited to 80 l/min, so circuit pumps must stay within that value. Working ports a, b, and p accept 350 bar, and the tank port endures 210 bar in DC service, enabling use in high-pressure machines.
A 24 V DC coil rated at 30 W provides the electromagnetic force needed to move the spool. An M12x1 four-pole connector speeds field wiring and supports plug-and-play replacement. The IP65 enclosure seals the solenoid against dust and water jets, and the coil surface may reach 120 °C, so surrounding components must withstand that heat. Maximum switching frequency is 1 Hz, guiding control logic to avoid undue wear. A concealed manual override permits manual actuation during commissioning or power loss without exposing the button to accidental use. An ISO 8752-3x8-St locating hole centers the body on the manifold and prevents rotation under vibration.
