The 4WE6G5X/BW120RNVP1Z2 valve is built by Bosch Rexroth for the WE Directional Spool Valves series and routes hydraulic flow in automated machinery. It uses nominal size 6 mounting, allowing direct placement on NG6 manifolds, and follows the ISO 4401-03-02-0-05 porting pattern so standard subplates can be used. A maximum operating pressure of 350 bar on pressure and work ports enables high-pressure circuits, while a 160 bar limit on the tank port protects the return line. The valve accommodates flow rates up to 60 l/min to match medium-capacity actuators. An IP65 enclosure guards the solenoids against dust and water jets, and the design can be installed in any position to simplify system layout.
The electrical section operates from a 120 V, 60 Hz supply, and a ±10 % voltage window tolerates minor line fluctuations. A 100 % duty cycle supports continuous energizing, with coil surface temperature restricted to 120 °C to prevent thermal damage. Switch-on power of 220 VA provides the initial magnet force, after which holding power drops to 50 VA to reduce energy use. Hydraulic fluid must meet ISO 4406 cleanliness class 20/18/15 to preserve spool accuracy. With two solenoids the assembly weighs 1.95 kg, allowing easy handling during installation or service.
