The 4WE6D6X/OFEW115N9K4/62SO43A-1751 valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and directs hydraulic flow in automated machinery. It carries spool symbol D to define its internal flow paths, and the detent spool return (code OF) holds the spool in its last actuated position for circuit stability. The unit supports a maximum flow of 60 l/min so that medium-size actuators can operate without restriction, while ports A, B, and P withstand pressures up to 350 bar for high-pressure systems. A porting pattern of ISO 4401-03-02-0-05 mates the valve to standard subplates, and an NFPA D03 interface offers interchangeability with North American manifolds. Because the installation position is unrestricted, designers can mount the valve in any orientation, provided the hydraulic fluid meets cleanliness class ISO 4406 20/18/15 to protect the spool and bore.
The solenoids run on a nominal supply of 115 V AC, delivered through a K4 connector that provides a 2-pole plus protective earth Form A interface for quick wiring. Class H insulation tolerates the heat generated when the coil surface reaches up to 120 °C during continuous duty. A concealed manual override identified by code N9 allows emergency actuation without exposing protruding parts, and a locating hole conforming to ISO 8752-3x8-St (/62) aligns the housing precisely on the subplate. Return port T is limited to 160 bar, ensuring safe back-pressure handling in closed-loop circuits. With two solenoids installed the valve weighs 1.95 kg, which eases handling during maintenance or manifold assembly.
