The 4WE6D6X/OFEW110NK4/V belongs to the WE Directional Spool Valves series from Bosch Rexroth and directs hydraulic flow in automated systems. It runs on a nominal supply of 110 V at 50 or 60 Hz, letting it connect to common control power lines, while a voltage tolerance of ±10 % shields operation from minor mains fluctuations. The coil is designed for a 100 % duty cycle so it may remain energized continuously without thermal overload. When first energized it draws 220 VA switch-on power to move the spool, after which holding power drops to 50 VA to minimize heating. Current demand is 0.52 A at 50 Hz and 0.39 A at 60 Hz, values used when selecting fuses or relays. Electrical connection is made through a DIN EN 175301-803-A plug coded K4, allowing quick installation and replacement in the field.
The hydraulic side tolerates 350 bar on ports P, A, and B, permitting use in high-pressure circuits, while the tank port is limited to 160 bar to protect return plumbing. A maximum flow rate of 60 l/min supports medium-sized actuators, and the spool can be shifted up to two times per second for repetitive on-off control. Installation follows the NFPA T3.5.1 D03 interface so the valve drops onto standard subplates, and its ISO 4401-03-02-0-05 porting pattern aligns passageways without modification. The housing meets IP65, which keeps dust and low-pressure water jets away from the coil and terminals. FKM seals identified by the suffix V resist common hydraulic oils and elevated temperatures, maintaining leak-free service life.
