The 4WE6D6X/OFEG12N9DA/B10 CSA valve belongs to the WE Directional Spool Valves series manufactured by Bosch Rexroth for hydraulic automation circuits that require electrically shifted flow paths. A wet-pin, high-power solenoid drives the spool so switching remains consistent under load, and the coil is wound for a 12 VDC supply that draws a rated current of 2.5 A to reach full stroke. Spool symbol D establishes two discrete flow positions that route pressure to either work port, while the OF detent keeps the spool in its last energized position after power is removed. A concealed manual override designated N9 lets technicians shift the valve locally during maintenance without disturbing enclosure integrity. The interface is ISO 4401-03-02-0-05, enabling direct mounting on standard subplates, and a throttle insert with a 1.0 mm orifice in port P (code B10) pre-meters inlet flow to damp rapid pressure changes.
The valve handles operating pressures up to 350 bar at ports P, A, and B, so it can control high-pressure actuators, while the tank port tolerates 210 bar for safe return flow. A maximum flow rate of 80 l/min defines the throughput the body and spool can accommodate without excessive Δp. Acceptable hydraulic media range from 2.8 to 500 mm²/s viscosity, allowing use with common mineral oils across seasonal temperature shifts. Fluid temperature may vary between −20 °C and +80 °C, and ambient conditions can sit between −20 °C and +50 °C, supporting outdoor machinery and cold starts. Meeting ISO 4406 cleanliness class 20/18/15 helps prevent silting of precision lands. NBR sealing elements resist oil swelling and maintain leakage control over long duty cycles.
