The 4WE6D6X/OFEW110N9K4/V CSA valve is manufactured by Bosch Rexroth within the WE Directional Spool Valves series. It directs hydraulic flow in automated circuits and is energized by a 110 V AC coil operating at 50 or 60 Hz to match general industrial supplies. A ±10 percent voltage tolerance permits stable function despite mains fluctuations, while the rated current of 0.52 A limits transformer sizing. The solenoid demands 220 VA at switch-on to overcome static friction and 50 VA holding power to minimize heat once the spool reaches its end position. Continuous 100 percent duty cycle (S1) supports uninterrupted cycling in production lines. Electrical connection is provided through a K4 DIN EN 175301-803 plug, which simplifies replacement and seals to IP65 when mated, the same protection class applied to the housing for splash resistance. A maximum switching frequency of two cycles per second in AC operation keeps the actuator within thermal limits and prevents premature wear.
In service, the valve manages up to 60 liters per minute, enabling medium-size actuator control without excess pressure drop. Pressure limits are 350 bar on ports P, A, and B to accommodate high-pressure supply lines, while port T is restricted to 160 bar in AC versions to protect the tank return gallery. FKM seals provide chemical resistance to common hydraulic oils and elevated temperatures, supporting long service life. ISO 4406 cleanliness class 20/18/15 is required to prevent spool sticking and maintain metering accuracy. A concealed N9 manual override allows local actuation during commissioning without exposing the mechanism to contamination. Together these attributes complete the hydraulic specification and confirm suitability for automated systems that need precise, reliable flow direction.
