The 4WE6D6X/OFEW110N9DAL/62 AN valve is manufactured by Bosch Rexroth within the WE Directional Spool Valves series. It shifts hydraulic flow paths in automation circuits and supports system pressures up to 350 bar on ports A, B, and P to match high-duty actuator requirements. The design passes up to 60 l/min while retaining stable spool positioning, and it presents four main ports for standard meter-in and return lines. Interface machining follows the ANSI B93.9 porting pattern, with a mounting surface roughness limited to Rzmax 4 to prevent leakage at the seal plane. A locating hole sized to ISO 8752-3x8-St aligns the body during installation, and the valve must be supplied with oil filtered to ISO 4406 20/18/15 to protect the precision lands.
The solenoid assembly operates on a nominal 110 V AC 50/60 Hz supply with a voltage tolerance of ±10%, allowing direct connection to common plant power. Continuous service is permitted because the coil is rated for a 100% ED duty cycle, and insulation class H supports a maximum surface temperature of 120 °C without thermal degradation. The actuator draws 220 VA during energization and settles to a holding power of 50 VA once the spool is fully shifted, conserving energy and limiting heat rise. Electrical hookup is made through a DAL 1/2-14 NPT conduit entry, and all components withstand tank port back-pressure up to 160 bar. These electrical and pressure limits complete the specification set for reliable spool control in automated hydraulic stations.
