4WE6RB6X/EW110RN9DK23L/V/62

The 4WE6RB6X/EW110RN9DK23L/V/62 directional spool valve is built by Bosch Rexroth as part of the WE Directional Spool Valves series. It directs hydraulic flow in automation circuits, using an NG6 valve size that fits compact manifolds. The R spool configuration establishes neutral and actuated flow paths suited for reversible actuator control. An ISO 4401-03-02-0-05 porting pattern allows direct mounting on standard sub-plates, minimizing piping. The unit handles up to 350 bar operating pressure so it can drive cylinders in high-pressure systems, while the tank port is limited to 160 bar to protect return-line components. A maximum flow of 60 l/min provides adequate volume for medium-sized actuators without inducing excessive pressure drop. Its solenoid is rated for continuous 100 % duty to keep the spool shifted as long as the control signal is present, and the coil accepts a 110 V 50/60 Hz supply for compatibility with common plant power.

The DK23L three-pole Mini-Change connector simplifies wiring and permits rapid replacement during maintenance. Coil holding power of 50 VA maintains the magnetic field without overheating, and a ±10 % voltage tolerance permits reliable operation despite mains fluctuations. The maximum coil surface temperature of 120 °C defines the thermal limit to avert insulation damage during continuous load. A concealed N9 manual override lets technicians shift the spool locally while safeguarding it against accidental activation. Ingress protection to IP65 prevents dust and low-pressure water from reaching internal parts when the connector is properly installed. FKM seals resist mineral oils and many synthetic fluids, extending service life in demanding environments. All these features combine to provide a directional control element that remains stable under electrical, thermal, and environmental stresses typical of automated hydraulic machinery.
