The 4WE6D6X/EW110DK25L/62 directional spool valve is produced by Bosch Rexroth as part of the WE Directional Spool Valves series and is used to route pressurized fluid in hydraulic automation circuits. Its nominal size is 6 (NG6), providing passage dimensions suited to medium-capacity lines, while the mounting interface follows ISO 4401-03-02-0-05 so the body fastens directly to standardized sub-plates; the complementary NFPA D03 interface supports North American manifolds. A maximum operating pressure of 350 bar permits use in high-pressure systems, and a maximum flow of 60 l/min defines the volume it can direct without excessive pressure drop. The tank port may be exposed to 160 bar, allowing back-pressure in return lines. Continuous energization is possible because the solenoid is rated for a 100 % duty cycle. Electrical power is supplied at 110 V AC on either 50 Hz or 60 Hz networks, matching industrial mains in most regions.
Electrical actuation characteristics begin with a switch-on power of 220 VA that magnetizes the coil during spool shift; once the armature is seated, holding power falls to 50 VA to limit heat rise. Insulation class H materials withstand internal temperatures, and the coil surface may reach 120 °C under prolonged load without degrading the winding. The DK25L five-pole connector with an integrated LED provides power and visual status in one plug, simplifying panel checks. A maximum switch-off overvoltage of 500 V protects upstream control electronics by limiting inductive spikes when the coil de-energizes. The locating hole specified as ISO 8752-3×8-St (/62) aligns the valve precisely on the manifold, preventing port mismatch during installation. All electrical and mechanical provisions together ensure reliable operation under the environmental and duty conditions typical of automated hydraulic machinery.
