4WE6D6X/EG205N5K4/V

The 4WE6D6X/EG205N5K4/V directional spool valve is built by Bosch Rexroth within the WE Directional Spool Valves series. It directs pressurized oil toward selected actuator ports to automate motion sequences in hydraulic machinery. A nominal size of 6 defines the flow section and matches compact manifold cavities. The ISO 4401-03-02-0-05 porting pattern aligns the valve body with standard subplates for quick installation. Four main ports support supply, return, and two work lines so circuit designers can route pressure and exhaust without additional blocks. The valve accommodates system pressures up to 350 bar on ports A, B, and P, letting it operate in high-pressure circuits. Tank port T is limited to 210 bar to protect return lines and reservoir components. A maximum flow of 80 l/min establishes the throughput the spool can pass without excessive pressure drop. Continuous energization is possible because the solenoid is rated for a 100 percent duty cycle. Electrical input is defined by a 205 V DC coil that draws 0.16 A and consumes 30 W, while a ±10 percent voltage tolerance allows for normal supply fluctuations.

The coil terminates through a DIN EN 175301-803 K4 connector, giving a sealed plug interface that matches common machine wiring looms. A large lockable mushroom-type manual override lets maintenance personnel shift the spool without electrical power when troubleshooting. Dynamic applications can be served because the valve reaches a switching frequency of 4.2 cycles per second under direct current operation. FKM seals are fitted, providing chemical resistance to modern hydraulic fluids and maintaining elasticity during long service life. The maximum ambient temperature of 50 °C ensures thermal stability of the coil and elastomers in typical machine enclosures. These characteristics complement the pressure and flow capabilities stated earlier and allow the valve to function reliably in continuous industrial service.
