The 4WE6X7-6X/EW110N9K4/N08 directional spool valve is manufactured by Bosch Rexroth for the WE Directional Spool Valves series and is used to route hydraulic flow in automated machinery. Valve size 6 sets the cavity dimensions for compact installations, while the ISO 4401-03-02-0-05 porting pattern aligns with standard subplates for quick mounting. The solenoid operates on 110 V AC at 50/60 Hz, letting control cabinets power the unit without conversion. It draws 220 VA at switch-on and drops to 50 VA in holding mode to limit heat buildup. A K4 plug in accordance with DIN EN 175301-803 supplies the electrical interface and allows rapid replacement. With IP65 protection, the envelope resists water jets and dust ingress when the connector is sealed. The coil is rated for a 100 % ED duty cycle so it can remain energized continuously without overheating.
The valve accommodates flows up to 60 l/min, supporting medium-capacity cylinders and motors. Pressure at ports P, A, and B may reach 350 bar, while port T withstands 160 bar to manage elevated return pressures. A 0.8 mm throttle insert in ports A and B moderates inrush flow for smoother spool transitions. NBR seals maintain compatibility with mineral oil hydraulics and retain elasticity across the working pressure range. The coil endures switch-off transients up to 500 V, preventing insulation damage when power is removed. A concealed manual override designated N9 enables local actuation during commissioning or fault recovery without protruding hardware. These features combine to provide reliable, precise switching for continuous hydraulic service in industrial automation.
