The 4WE6G6X/EW110N9DL is a directional spool valve built by Bosch Rexroth for the WE Directional Spool Valves series. It directs fluid between pressure, actuator, and return ports in hydraulic automation systems. The valve is designed for subplate connection using the ISO 4401-03-02-0-05 interface, matching manifolds intended for nominal size 6 cavities. Its solenoid operates on a 110 V AC supply, and the coil accepts voltage variations of ±10 percent so cabinet power tolerances do not disturb shifting. When energized, the inrush demand reaches 220 VA, while steady holding power drops to 50 VA to limit temperature rise. Continuous service is possible because the coil is rated for a 100 percent duty cycle and its surface temperature may rise up to 120 °C without damage. These electrical limits allow the valve to remain actuated for long periods in machine tools and presses.
Hydraulic performance is centered on a maximum operating pressure of 350 bar at ports p, a, and b, allowing the valve to control high-pressure cylinders. Return flow can be routed to tank lines up to 160 bar, and the passage accommodates flow rates to 60 l/min so medium-size actuators move without restriction. A concealed N9 manual override is provided; it can be engaged safely at tank pressures up to 50 bar to shift the spool during commissioning or power loss. The enclosure carries an IP65 rating, preventing dust ingress and water-jet intrusion in exposed installations. Fluid cleanliness must meet ISO 4406 class 20/18/15, reducing spool wear and sticking. Together these characteristics define a compact valve that withstands harsh environments while maintaining precise directional control in automated hydraulic circuits.
