The 4WEH22D7X/6EG24N9S2K4 directional spool valve belongs to the WEH Directional Spool Valves series and is manufactured by Bosch Rexroth for controlling high-volume hydraulic flow in automated machinery. With a nominal size of NG25, it handles up to 450 l/min, allowing rapid actuator movement in large circuits. A maximum operating pressure of 280 bar at ports P, A, and B supports heavy-duty loads, while port T withstands 250 bar to keep return lines safe. External pilot oil supply at port X and external pilot return at port Y isolate control pressure from the main flow path; the pilot section functions reliably between 11 bar and 210 bar. Subplate mounting pairs with the ISO 4401-08-08-0-05 porting pattern so the valve can be swapped without disturbing pipework. NBR seals resist common mineral oils and maintain leakage control. The permissible contamination level is ISO 4406 20/18/15, so filtration must match this rating to protect the spool surfaces.
The valve’s wet-armature solenoids are energized with a 24 V DC coil, enabling direct interface with standard machine power supplies. Electrical termination uses a DIN EN 175301-803 K4 connector, giving quick disconnect capability during maintenance. A concealed manual override lets technicians shift the spool when power is absent, yet stays protected from accidental use. The design achieves an MTTFd of 100 years, demonstrating a low probability of dangerous failure throughout long service life. Together, the defined voltage, connector style, and override arrangement simplify electrical integration and on-site servicing without compromising reliability.
