4WE6D6X/OFEW110N9K4/ZV

The 4WE6D6X/OFEW110N9K4/ZV directional spool valve is manufactured by Bosch Rexroth for the WE Directional Spool Valves series. Designed to route pressurized fluid in hydraulic automation circuits, the unit conforms to the ISO 4401-03-02-0-05 porting pattern so it aligns with common NG6 manifolds. A clamping length of 22 mm sets the stack height and ensures even gasket compression. The valve withstands 350 bar on ports P, A, and B, allowing high-pressure actuation of cylinders or motors, while the tank port safely handles up to 160 bar to accommodate back-pressure conditions. A maximum flow rate of 60 l/min lets the spool pass sufficient volume for medium-speed actuators. Continuous operation is supported by a 100 % ED duty cycle, so the solenoids may remain energized without thermal interruption. During energization the solenoid draws 220 VA as switch-on power to shift the spool, then settles to a 50 VA holding power for steady state to limit heat and energy demand.

Electrical connection is made through a DIN EN 175301-803 K4 plug, which provides quick wiring and standardized pinout for field replacement. The coils are wound for 110 V at 50 or 60 Hz, matching common control voltages in industrial plants. A maximum switching frequency of two cycles per second allows reliable directional changes without excessive wear. This switching rate aligns with proportional pressure control loops used in automated machinery. The enclosure meets IP65, giving full dust protection and resistance to low-pressure water jets for exposed machine locations. FKM seals are fitted to tolerate aggressive hydraulic fluids and elevated temperatures. A concealed manual override, coded N9, lets maintenance staff shift the spool mechanically during commissioning or power loss. With two solenoids installed, the assembly weighs 1.95 kg, a moderate mass that eases overhead installation while maintaining rigid seating on the subplate.
