4WE6D6X/OFEW110N9K4SO43A-1755

The 4WE6D6X/OFEW110N9K4SO43A-1755 directional spool valve is manufactured by Bosch Rexroth within the WE Directional Spool Valves series. It shifts hydraulic flow between actuator ports in automated machinery. The coil is rated for a nominal supply of 110 V AC at 50 or 60 Hz, allowing direct connection to common plant power. A switch-on power demand of 220 VA ensures rapid spool movement, while the holding power drops to 50 VA to limit heat during steady energization. Continuous service is possible because the solenoid is specified for a 100 % duty cycle. Electrical termination uses a K4 connector compliant with DIN EN 175301-803, so cable sets can follow industry wiring standards. Ingress protection is IP65, enabling installation where water spray or dust are present. A concealed N9 manual override permits local actuation during commissioning, and the OF detent keeps the spool in its last position without coil power when required.

The hydraulic section supports a maximum flow of 60 l/min, providing adequate capacity for moderate cylinder or motor sizes. Ports a, b, and p withstand operating pressures up to 350 bar, while the tank port is limited to 160 bar when the valve is run on an AC coil, safeguarding the return circuit components. The permitted switching frequency is 2 cycles per second, which matches applications that demand frequent yet controlled directional changes. Mounting follows the ISO 4401-03-02-0-05 porting pattern, and an NFPA T3.5.1 D03 interface is included to simplify interchange with North American manifold blocks. Two installed solenoids bring the assembled weight to 1.95 kg, light enough for direct stacking on compact sub-plates. These characteristics allow the valve to regulate bidirectional actuator flow while maintaining consistent response and service life in industrial hydraulic systems.
