The 4WE6D6X/OFEG140N9K4/V/62 directional spool valve is produced by Bosch Rexroth for the WE Directional Spool Valves series. It directs hydraulic flow to actuators in automated machinery where rapid, repeatable switching is required. A maximum operating pressure of 350 bar permits use in high-pressure circuits. The valve passes up to 80 l/min, supporting medium-capacity power units. Its ISO 4401-03-02-0-05 mounting interface matches the NFPA T3.5.1 D03 pattern so it drops onto standard subplates. The solenoid system draws 30 W at nominal load, and the 100 % duty cycle allows continuous energization without overheating. Coil surface temperature is permitted to reach 120 °C before thermal limits are met.
A detent designated OF holds the spool in its shifted position after the coil is de-energized. The concealed manual override marked N9 provides local actuation during setup or power loss. Electrical connection is made through a DIN EN 175301-803 K4 plug, while insulation class F supports higher winding temperatures. The housing carries an IP65 rating to block dust ingress and low-pressure water jets. Precise alignment on the manifold is aided by an ISO 8752-3x8 locating pin hole referenced as /62. FKM seals resist common hydraulic oils and elevated temperatures. Port T tolerates back-pressure up to 210 bar to protect the return circuit. With both solenoids installed the assembly weighs 1.95 kg, easing installation by a single technician.
