The 4WE6EA6X/EW110N9/V/62SO43A-1221B valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and shifts hydraulic flow paths in automated systems. The wet-pin high-power solenoid provides rapid actuation suited to frequent cycling. A rated voltage of 110 V AC allows direct connection to standard control transformers. The coil tolerates ±10 % voltage variation so it remains functional during supply fluctuations. Switch-on power of 220 VA defines the inrush demand that the electrical circuit must support. After energization, holding power drops to 50 VA to limit continuous heat generation. Continuous operation is possible because the duty cycle is 100 % ED. Insulation class H safeguards the winding against the temperatures reached during prolonged service, and compatibility with 50/60 Hz mains frequency simplifies installation in regions with either standard.
Maximum operating pressure of 350 bar on ports A, B, and P lets the valve work in high-pressure circuits. The unit handles up to 160 bar on the tank port, ensuring safe return flow conditions. A nominal flow capacity of 60 l/min regulates circuit sizing for pumps and actuators. The ISO 4401-03-02-0-05 porting pattern matches common manifold blocks for quick installation, while mounting follows the NFPA T3.5.1 D03 interface for interchange with other D03 valves. A locating hole sized ISO 8752-3x8-St (/62) centers the body during manifold assembly. A concealed manual override (N9) lets maintenance staff shift the spool without electrical power. FKM seals withstand aggressive hydraulic fluids and elevated temperatures.
