The 4WEH16Q7X/6EW110N9ETK4/B10 SO269 directional spool valve is manufactured by Bosch Rexroth for the WEH Directional Spool Valves series. It directs hydraulic flow to actuators in automated machinery where rapid and precise switching is required. The valve is supplied in NG16 size, accommodating medium frame circuits while keeping installation consistent with the ISO 4401-07-07-0-05 mounting surface for quick manifold integration. Its Q spool establishes the flow paths that deliver a maximum of 300 l/min so cylinders or motors receive sufficient volume at high cycle rates. Operating chambers A and B can withstand pressures up to 280 bar, allowing the unit to handle common industrial power levels without external pressure reducers. When centered, the spool leaves a 32 mm² cross-section open, reducing leakage while maintaining predictable standby flow characteristics. A Ø 1.0 mm throttle insert labeled B10 smooths pilot oil transitions and damps pressure spikes during shifting. A concealed N9 manual override lets technicians shift the valve during commissioning or power loss without risking inadvertent actuation in daily use.
For reliable control of the pilot stage, the valve connects to logic or PLC outputs through a DIN EN 175301-803 K4 electrical plug, simplifying wiring with standardized pin assignments. Pilot oil exhausts externally via port Y, so tank line back-pressure does not influence spool movement, and the return path can tolerate up to 160 bar to suit remote reservoir layouts. The pilot supply may reach 250 bar, giving adequate force to overcome spring and flow forces, while spring-centered versions begin to operate at 14 bar, ensuring responsiveness even in low pressure start-up scenarios. The assembly weighs 8.9 kg with two solenoids and centering springs, permitting single-person handling during maintenance. Ambient operation is specified from −20 °C to +50 °C, enabling use in unheated plants or warm production halls without additional climate control.
