4WE6D6X/OFEG24N9K72L/62

The 4WE6D6X/OFEG24N9K72L/62 is supplied by Bosch Rexroth within the WE Directional Spool Valves series and is used to route hydraulic flow in automated machinery. It is built to nominal size 6, so it fits subplates that share this cavity dimension without adapters. The ISO 4401-03-02-0-05 porting pattern defines the mounting face and seal positions, making the valve interchangeable with other components that follow the same standard. A maximum flow of 80 l/min sets the highest volume the spool can pass while holding acceptable pressure drop. Supply and working ports P, A, and B tolerate up to 350 bar, while the tank port T is limited to 210 bar, establishing safe limits for pressure line and return line design. Fluid cleanliness must stay at ISO 4406 20/18/15 or better to keep the sliding spool free of abrasive wear. An IP65 protection class encloses the coil and connector against dust and low-pressure water spray encountered in factory environments.

The solenoid is energized with a nominal voltage of 24 V DC, which matches common machine control power supplies. During steady activation it draws a rated current of 1.25 A, resulting in a 30 W power demand that must be provided by the electrical cabinet. The M12×1 four-pin connector with coding A offers a keyed interface that speeds up wiring and prevents cross-connection. An integrated suppressor diode clamps the inductive voltage spike when the coil is switched off, protecting output transistors in the PLC. Continuous operation is permitted because the coil is rated for a 100 % ED duty cycle, eliminating cooling pauses in cyclic processes. The spool can be shifted up to once per second, as limited by the maximum switching frequency of 1 Hz, so timing diagrams must respect this rate. A locating hole to ISO 8752-3×8-St aligns the valve on the subplate, ensuring the ports seal correctly during assembly.
