The 4WE6E73-6X/EW110RN9DAL/A12/62 valve is built by Bosch Rexroth in the WE Directional Spool Valves series. It directs hydraulic flow between actuator and supply lines in automated systems. The mounting interface matches NFPA D03 to fit standardized subplates, and the nominal size 6 establishes its flow capacity. A porting pattern of ISO 4401-03-02-0-05 aligns each pressure, tank, and work port for easy manifold integration. The unit tolerates a maximum operating pressure of 350 bar so it can control high-pressure circuits, while the tank port is limited to 160 bar to protect return lines. A peak flow rating of 60 l/min prevents excessive pressure drop during rapid actuator movement. The enclosure carries an IP65 protection class which seals the coil and wiring against dust and water spray in industrial environments.
The solenoid coil is wound for 110 V AC at 50 or 60 Hz, allowing direct connection to common control transformers. Under both frequencies the coil draws 0.34 A so panel fusing remains the same worldwide. A 100 % ED duty cycle permits continuous energization without thermal cycling, and a maximum surface temperature of 120 °C defines the limit for insulation life. Electrical termination follows the DAL pattern with a 1/2-14 NPT conduit entry to accept standard flexible metal conduit in plant wiring. A concealed N9 manual override lets maintenance personnel shift the spool during commissioning without disturbing the solenoid circuit. A locating hole equipped with a locking pin to ISO 8752-3x8-St centers the body on the subplate and prevents lateral movement. Together these features secure, energize, and manually control the valve during normal service.
