The 4WE6E6X/EW110N9DK25L/62 CSA-AN directional spool valve is produced by Bosch Rexroth within the WE Directional Spool Valves series and directs hydraulic flow to actuators and return lines in automated circuits. The porting pattern follows ANSI B93.9 (NFPA D03), allowing direct installation on standard size 6 subplates. A maximum operating pressure of 350 bar at ports A, B, and P lets the valve handle high-pressure supply lines, while a maximum tank port pressure of 160 bar defines the safe limit for the return path. Its permitted flow reaches 60 l/min so medium-capacity systems can be controlled without restriction. A maximum switching frequency of 2 cycles per second enables moderate cycling duties. The coil is rated for a 100 % duty cycle, meaning it can remain energized continuously, and insulation class H withstands the heat generated during such long operation.
Nominal energization is 110 VAC, and a voltage tolerance of ±10 % keeps the valve functional during supply fluctuations often found in plant power networks. An inrush demand of 220 VA must be available at switch-on, after which holding power drops to 50 VA to reduce continuous load on the transformer. The DK25L five-pole electrical connector with an integrated indicator light streamlines wiring and gives a clear visual signal when the solenoid is powered. A concealed manual override (N9) lets maintenance staff shift the spool without energizing the coil, and this feature is rated for a maximum tank pressure of 50 bar to prevent seal damage during manual strokes. A locating hole with a locking pin (/62) fixes the body precisely on the manifold to resist vibration. Hydraulic cleanliness must not exceed ISO 4406 code 20/18/15 to preserve spool accuracy and prevent premature wear.
