The 4WE6D5X/OFBW120RNVP1Z2 directional spool valve belongs to the WE Directional Spool Valves series and is manufactured by Bosch Rexroth. It directs hydraulic flow in automated machinery and is energized by a solenoid rated for 120 V AC at 60 Hz. Switch-on power reaches 220 VA, while holding power falls to 50 VA, allowing transformers to be sized for both inrush and steady states. A 0.30 A rated current delivers consistent magnetic force, and a 100 % duty cycle permits continuous activation. The coil uses insulation class H material and may operate with a surface temperature up to 120 °C without damage. Dust-tight, water-jet protection is confirmed by an IP65 enclosure rating, so the valve can be mounted in exposed plant areas.
The hydraulic body supports up to 60 l/min of flow through pressure and work ports that tolerate 350 bar, while the tank port withstands 160 bar. This flow rating informs pump selection and avoids excessive pressure loss during shifting. Reliable service continues between ambient temperatures of −15 °C and +50 °C, accommodating unconditioned facilities. System fluid must meet ISO 4406 code 20/18/15 to protect the precision-ground spool from wear. Installation aligns with the NFPA T3.5.1 D03 interface, and the port layout matches ISO 4401-03-02-0-05, enabling direct mounting on standard subplates. These mechanical standards reduce setup time and ensure leak-free connections.
