The 4WE6D73-6X/OFEG24N9K4/A12/62 CSA directional spool valve is produced by Bosch Rexroth in the WE Directional Spool Valves series. It directs pressurized fluid to actuators or returns it to tank within hydraulic automation circuits. The valve offers two detented spool positions that hold their state without continuous power. Actuation relies on a wet-pin solenoid with a detachable coil, set for 24 V DC and a steady-state current draw of 1.25 A. A nominal power demand of 30 W keeps control cabinet loads low, and a 100 percent duty cycle permits uninterrupted energization. A locating hole with a locking pin, designated by the /62 suffix, aligns the body on the mounting surface. For manual intervention, a concealed override identified as N9 is available.
Hydraulic capacity reaches 80 L/min of flow while maintaining accurate spool positioning. Ports a, b, and p withstand operating pressures up to 350 bar, whereas the tank port t is limited to 210 bar. The magnetic system supports a maximum switching frequency of 4.2 operations per second, allowing responsive machine cycles. Manifold attachment follows the ISO 4401-03-02-0-05 porting pattern to match standard interface plates. The housing meets the IP65 protection class, preventing dust ingress and resisting low-pressure water jets during wash-down. Overall weight is 1.95 kg, enabling straightforward installation without lifting equipment. These parameters define the valve’s performance envelope in fixed or mobile hydraulic control assemblies.
