The 4WE6H6X/EW110N9K4/V valve belongs to the WE Directional Spool Valves series and is manufactured by Bosch Rexroth for hydraulic automation where controlled port switching is required. It uses valve size 6 to fit systems that follow common CETOP 03 dimensions. A spool coded H defines its internal flow paths for consistent actuation of cylinders and motors. The porting pattern ISO 4401-03-02-0-05 aligns the body with sub-plates and manifolds that share this international standard. The assembly handles a maximum flow rate of 60 l/min so circuits can achieve moderate speeds without excessive pressure loss. Working pressure on ports A, B, and P is permitted up to 350 bar, while the T port is limited to 160 bar to protect return lines. FKM seals resist mineral oil and many synthetic fluids, supporting long service life. An IP65 protection class prevents dust ingress and low-pressure water jets from affecting the solenoids or connections.
The solenoid section is energized from a 110 V AC supply at either 50 or 60 Hz, allowing installation on standard plant mains. Switch-on power is 220 VA to generate the magnetic force needed for reliable spool shift, after which holding power drops to 50 VA to reduce heat and energy use. The current drawn at 50 Hz is 0.52 A, data that aids fuse and relay selection. A K4 connector compliant with DIN EN 175301-803 provides quick plug-in wiring and maintains sealing against spray. Control redundancy is available through a concealed N9 manual override that lets maintenance staff move the spool without electrical power. Continuous duty operation is possible because the coil is rated for a 100 % duty cycle, preventing thermal overload during prolonged energization. Two solenoids bring the assembly weight to 1.95 kg, light enough for manifold mounting without additional support.
