The 4WE6W73-6X/EG24N9DK35L/A12/62 valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and is intended to direct hydraulic flow in automation systems. It uses the size 6 envelope so it fits compact manifolds without adding excess bulk. A porting pattern of ISO 4401-03-02-0-05 allows direct mounting on standardized sub-plates for quick change-out. The pressure ports p, a, and b can withstand up to 350 bar, while the tank port t is limited to 210 bar, supporting high-pressure work circuits and controlled return flow. Continuous service is possible because the solenoid is rated for a 100 percent duty cycle. The valve handles 80 l/min of direct-current flow so actuators receive adequate supply. Electrical control is based on a nominal 24 V DC input that may vary ±10 percent, drawing a rated 1.25 A and consuming 30 W during energized states.
The coil surface is allowed to reach 120 °C, defining the maximum temperature for safe operation in heated manifolds. An IP65 ingress rating shields internal parts from dust and water jets encountered on production lines. Electrical safety is classified as VDE 0580 class III, indicating protective separation from higher-voltage equipment. The spool can shift up to 4.2 times per second, enabling moderate cycling in indexing or clamping duties. Hydraulic fluid must meet cleanliness class ISO 4406 20/18/15 to prevent wear on the precision-ground lands. Total mass is 1.95 kg, so a single technician can install or replace the unit without lifting aids.
