4WE10HA3X/CW110N9K4

The 4WE10HA3X/CW110N9K4 valve belongs to the WE Directional Spool Valves series and is manufactured by Bosch Rexroth for hydraulic automation systems that require dependable flow direction control. It is built with a nominal size of 10 so it fits into medium frame manifolds, and its CETOP D05 mounting interface aligns with standardized subplate layouts. The porting pattern follows ISO 4401-05-04-0-05 which permits quick exchange with other components configured for the same footprint. Electrical actuation is provided by a 110 V AC coil that accepts either 50 Hz or 60 Hz supplies, allowing global panel compatibility. When the coil is energized, the circuit must supply 550 VA during switch-on, after which consumption drops to a steady 90 VA to limit heat and power draw. Continuous energization is allowed because the winding is rated for a 100 percent duty cycle. Field wiring is simplified by a DIN EN 175301-803 plug coded K4, ensuring a keyed connection that prevents misalignment.

The hydraulic section supports a maximum flow of 120 l/min, enabling the valve to route oil for cylinders or motors in moderately sized machines. Working ports A, B, and P may be pressurized up to 315 bar, while the tank port T is limited to 160 bar, a distinction that protects return lines from excessive load. For high-speed sequences the spool can shift up to 7 200 times per hour, so rapid cycles are possible without overheating. A concealed manual override identified as N9 lets maintenance staff shift the spool locally without removing protective covers, which is useful during commissioning or in the event of power loss. Environmental sealing meets IP65, guarding the coil and internal connections against dust ingress and low-pressure water jets. Fluid cleanliness must remain better than ISO 4406 20/18/15 to prevent wear of the precision spool lands and maintain dependable switching. These hydraulic, mechanical, and environmental capabilities align the valve with demanding industrial motion tasks.
