The 4WE6X7-6X/EW230N9K4/62 CSA valve is manufactured by Bosch Rexroth and belongs to the WE Directional Spool Valves series, where it serves to shift hydraulic flow paths in automation circuits. Its nominal size of 6 (NG6) defines the mounting envelope, while the ISO 4401-03-02-0-05 (NFPA D03) porting pattern aligns the ports with common sub-plates. A high-power wet-pin solenoid supplies the mechanical force needed to move the spool under oil immersion. The coil is rated for a 230 V AC supply at 50/60 Hz, and a ±10 % voltage tolerance keeps the actuator functional when mains levels fluctuate. Switch-on power reaches 220 VA during energizing, then the holding power drops to 50 VA to reduce heat. A 100 % ED duty cycle allows the coil to stay energized continuously without thermal derating, supporting uninterrupted machine operation.
The hydraulic side is specified for a maximum operating pressure of 350 bar on pressure ports, while the tank port is limited to 160 bar to protect return-line components. Flow capacity peaks at 60 l/min, matching medium-size actuator demands. An IP65 enclosure guards the solenoid housing against dust ingress and water jets, and the winding system meets insulation class H so higher internal temperatures can be tolerated. The electrical connection follows the K4 interface in DIN EN 175301-803, providing a readily available plug style for field wiring. A concealed N9 manual override lets maintenance personnel shift the spool mechanically without exposing protruding hardware. Together, these features equip the valve for reliable service in industrial hydraulic manifolds.
