The 4WE6D6X/EW110RN9DK6L/B10V valve belongs to the WE Directional Spool Valves series and is manufactured by Bosch Rexroth to route hydraulic flow in automated machinery. The solenoid operates on a nominal supply of 110 V AC at 50 or 60 Hz, and it draws 220 VA at switch-on to move the spool, then drops to 50 VA holding power to limit coil temperature. A 100 % ED duty cycle lets the coil stay energized continuously for uninterrupted control. Electrical hookup is through a DK6L seven-pole connector that simplifies installation and feedback wiring. The coil accepts a voltage variation of ±10 %, maintaining reliable switching under line fluctuations. An IP65 enclosure protects the unit against dust and water jets, and a concealed N9 manual override lets maintenance staff shift the spool mechanically when power is not available.
The valve uses the ISO 4401-03-02-0-05 (D03) porting pattern, allowing direct mounting on standard subplates without reworking pipe connections. Ports A, B, and P tolerate pressures up to 350 bar, while the tank port withstands 160 bar so that back-pressure surges do not damage the housing. A flow capacity of 60 l/min supports medium-sized actuators, and a switching frequency of two cycles per second enables rapid motion sequences. A throttle insert with a 1.0 mm orifice in port P limits inrush flow to reduce hydraulic shock during actuation. FKM seals provide chemical resistance to common mineral and synthetic oils, supporting long service life in demanding industrial or mobile equipment.
