The 4WE6E6X/EG24K4QS0G24W directional spool valve belongs to the WE Directional Spool Valves series and is built by Bosch Rexroth for hydraulic automation systems that need reliable flow path selection. The nominal size 6 establishes the internal passage dimensions, while the ISO 4401-03-02-0-05 porting pattern lets the unit mount on standard sub-plates without adapters. A maximum operating pressure of 350 bar on ports P, A, and B allows the valve to work in high-pressure circuits, and the tank port withstands 210 bar in direct-current service. The design passes up to 80 l/min, giving adequate capacity for medium-flow manifolds. Continuous energization is supported by a 100 % duty cycle, and the DIN EN 175301-803 K4 electrical connector provides a sealed plug-in interface. The solenoid requires a 24 V DC supply and draws a rated 1.25 A, so power electronics can be sized accordingly.
Nominal coil power is 30 W, defining the electrical load that must be dissipated during sustained actuation, and the coil surface may reach 120 °C without exceeding its thermal rating. The valve can cycle up to 4.2 times per second, which supports rapid directional changes in servo-controlled machinery. An IP65 ingress protection rating shields the enclosure from dust and low-pressure water jets, enabling installation near process equipment. To maintain performance, hydraulic fluid cleanliness must meet ISO 4406 code 20/18/15, limiting particle ingress to the spool bore. The assembly with two solenoids weighs 1.95 kg, a factor when sizing manifold supports or robot end effectors. These characteristics allow the component to deliver consistent switching accuracy and service life in industrial hydraulic controls.
