4WE6H73B6X/EG24N9K72L/A12 AN

The 4WE6H73B6X/EG24N9K72L/A12 AN directional spool valve belongs to the WE Directional Spool Valves series produced by Bosch Rexroth for machine and mobile hydraulic automation. It directs pressurized fluid between supply, work, and tank lines to start, stop, or change actuator motion. The valve is built in size 6, matching subplate cavities intended for compact manifolds. A porting pattern that follows ANSI B93.9 (D03) permits direct mounting on standard CETOP 03 bases. Maximum operating pressure at ports P, A, and B is 350 bar so the unit can handle high-pressure circuits, while the tank port withstands 210 bar to protect return plumbing. Allowed flow of 80 l/min sets the upper limit for actuator speed in direct-current service. The coil is energized at a nominal 24 V DC, drawing a rated current of 1.25 A, and the ±10 % voltage tolerance lets it remain functional when supply fluctuates.

Continuous duty is supported by a 100 % ED rating, enabling the solenoid to stay powered without thermal cycling. Nominal power consumption of 30 W defines heat generation that must be removed by natural convection. The coil surface may reach 120 °C, a temperature that determines insulation selection and spacing to adjacent components. An M12×1 four-pole electrical connector provides quick attachment to control cables and simplifies field replacement. The housing carries an IP65 ingress protection rating, sealing the internal coil against dust and low-pressure water jets in industrial environments. A concealed manual override lets maintenance personnel shift the spool during commissioning or power loss without risking accidental activation. The product weighs 1.95 kg, so panel or manifold supports must carry that mass plus hydraulic reaction forces. These features work together to give precise directional control in automated hydraulic systems driven by direct-current solenoid technology.
