The 4WE6E6X/EW110NDAL/62 valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and directs hydraulic flow in automated circuits. It operates with a nominal coil voltage of 110 V AC at 50/60 Hz, enabling straightforward connection to common control transformers. An inrush demand of 220 VA supplies the magnetic force required to shift the spool at energization. Once actuated, coil holding power falls to 50 VA, which limits heat during prolonged energization. The solenoid draws a rated current of 0.39 A at 60 Hz, a value used when selecting circuit protection. A voltage tolerance of ±10 % keeps switching reliable despite moderate supply fluctuations. Continuous duty is possible because the assembly is rated for a 100 % ED duty cycle. An IP65 protection class and a weight of 1.95 kg for the two-solenoid version permit installation on exposed machinery without excessive mass.
The spool section withstands 350 bar on the pressure, A, and B ports, fitting high-pressure hydraulic circuits, while the return port is limited to 160 bar. A maximum flow capacity of 60 l/min allows medium-sized actuators to operate without significant pressure loss. The mounting interface follows ISO 4401-03-02-0-05, so the body bolts directly to standard NG6 subplates, and a locating pin defined as ISO 8752-3x8 centers the valve during assembly. Manual override remains usable when tank pressure does not exceed 50 bar, providing maintenance or emergency actuation. Required oil cleanliness is ISO 4406 20/18/15 to protect the spool and seals from wear. These mechanical and hydraulic limits define the valve’s operating envelope in continuous service.
