4WE6D6X/OFEW110RN9DAL/62

The 4WE6D6X/OFEW110RN9DAL/62 directional spool valve is produced by Bosch Rexroth within the WE Directional Spool Valves series and is used to route hydraulic flow in automated machinery. A duty cycle of 100% ED allows the solenoid to remain energized continuously without overheating, supporting round-the-clock machine cycles. The valve is energized from a nominal 110 V AC supply at either 50 or 60 Hz, so it integrates with standard plant power. During steady operation it draws 0.34 A at 50 Hz, which helps designers rate control transformers and protection devices accurately. Initial energization requires 220 VA of switch-on power to overcome magnetic and hydraulic forces and shift the spool. Once the spool is seated, holding power falls to 50 VA, reducing energy consumption and limiting temperature rise in the coil. A high-power wet-pin solenoid encloses the coil in hydraulic fluid, which carries away heat and resists particle ingress. Wiring is completed through a DAL 1/2-14 NPT conduit entry, giving a secure threaded interface for flexible metallic conduit.

Flow paths return to their original state with a detent spool return, so the spool stays in its last position after power is removed. The porting pattern follows ISO 4401-03-02-0-05, enabling direct mounting on standardized subplates without custom drilling. Maximum flow capacity is 60 l/min, matching medium-size actuator circuits in industrial presses or test rigs. Ports P, A, and B withstand operating pressures up to 350 bar, allowing the valve to handle high-pressure supply lines. The tank port is limited to 160 bar, so reservoir lines can be sized accordingly to prevent backpressure issues. An IP65 protection class seals the housing against dust and low-pressure water jets, permitting installation in wash-down areas. A concealed N9 manual override lets maintenance personnel shift the spool mechanically when electrical power is unavailable. The locating hole conforms to ISO 8752-3x8-St, which simplifies alignment on the subplate during assembly. With two solenoids fitted the valve weighs 1.95 kg, light enough for one-hand installation yet substantial enough to resist vibration.
