The 4WE6J6X/EG24K72L/62 valve belongs to the WE Directional Spool Valves series and is manufactured by Bosch Rexroth. It directs hydraulic flow to actuators in automated machinery and is energized by a 24 V DC supply that drives the solenoid. A rated current of 1.25 A defines the electrical load for control circuits, while the M12x1 4-pole connector identified as K72L provides plug-in wiring. The enclosure carries an IP65 rating, so the electrical parts resist dust and low-pressure jets of water encountered in industrial environments. NBR seals are fitted to hold back common mineral oil media, and the valve operates with hydraulic fluid temperatures between −20 and +80 °C. It accommodates viscosities from 2.8 to 500 mm²/s without loss of function, and the required oil cleanliness is ISO 4406 class 20/18/15 to prevent spool wear.
The mounting face follows the ISO 4401-03-02-0-05 porting pattern and matches the NFPA D03 interface, so the valve can replace standard size units without re-machining manifolds. A nominal size of 6 sets the flow passages and supports a maximum flow of 80 l/min through the direct-controlled spool. The pressure at ports A, B, or P may reach 350 bar, whereas back-pressure at port T is limited to 210 bar to protect the tank return line. A locating hole with a locking pin ISO 8752-3×8 holds the body in position on the subplate during service. These hydraulic limits and mechanical restraints let the valve perform repeatable directional switching in compact power packs and distributed control blocks.
