The 4WE6G6X/EW230N9DL valve belongs to the WE Directional Spool Valves series and is manufactured by Bosch Rexroth. It directs pressure media to selected actuator ports in hydraulic automation systems. Size 6 defines a compact envelope that fits small subplates while still supporting a maximum flow of 60 l/min for medium-duty circuits. The porting pattern ISO 4401-03-02-0-05 aligns the body with standard CETOP 03 manifolds so no custom drilling is required. A maximum operating pressure of 350 bar on ports A, B, and P lets the valve work in high-pressure installations without internal leakage growth. Continuous energization is permitted because the duty cycle is 100%. The solenoid accepts a 230 V supply at either 50 or 60 Hz, and the ±10 % voltage tolerance keeps operation stable when line voltage fluctuates. During energization the coil draws a switch-on power of 220 VA, information needed for sizing control transformers.
For steady state conditions the coil drops to a holding power of 50 VA, lowering heat generation and energy use. Insulation class H supports winding temperatures associated with a maximum coil surface temperature of 120 °C, preventing premature insulation failure. The valve withstands 160 bar on the tank port to protect return-line components. A maximum switching frequency of two actuations per second safeguards against overheating in rapid-cycle machines. Central electrical connection DL groups conductors in one plug so wiring is straightforward during panel assembly. The concealed manual override N9 allows mechanical shifting when power is absent while protecting the button from accidental actuation. To maintain internal clearances, hydraulic fluid purity must meet ISO 4406 class 20/18/15, and adherence to this cleanliness level extends spool life.
