The 4WE6J73-6X/EG96NK4/A12/62 directional spool valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and is used to route pressurized fluid in hydraulic automation. It tolerates a maximum operating pressure of 350 bar for pressure lines, and a flow of up to 80 l/min can move through the metering slots when the coil is energized. Return port T is limited to 210 bar to protect downstream tank plumbing. The mounting interface matches the ISO 4401-03-02-0-05 pattern, allowing the valve to stack with standard subplates. NBR sealing elements resist common mineral oils found in industrial power units. Actuation relies on a high-power wet-pin solenoid that keeps armature components lubricated by the hydraulic fluid. The coil is rated for 96 V DC, and the magnetic circuit remains functional with supply variations of ±10 percent.
Continuous service is possible because the electromagnetic assembly is specified for a 100 percent duty cycle. During normal operation the coil draws 30 W, supporting energy calculations for control cabinet supplies. Electrical connection is made through a K4 plug conforming to DIN EN 175301-803, and a correctly installed connector yields an IP65 degree of protection against dust and water jets. A locating hole sized for an ISO 8752-3×8 pin aids precise alignment on modular manifolds, while a manual override lets maintenance staff shift the spool without power. Coil surface temperature may reach 120 °C, so adjacent components must tolerate that heat. The A12 configuration ensures smooth switching to reduce hydraulic shock in sensitive circuits.
