Total price
This size 10 proportional directional valve drives medium actuators at 50 l/min nominal flow. Neither pilot inlet nor pilot return needs its own line, so installation is limited to a standard subplate to ISO 4401-05-05-0-05.
Benefits
- Fully internal pilot stage: installation without any additional pilot lines
- 50 l/min nominal flow with headroom up to 170 l/min maximum flow
- Spool symbol W6, 3 switching positions, 4 ports, 315 bar operating pressure
- ±10 V command through the on-board electronics, no amplifier card required
- At 8.43 kg light enough to be mounted on moving assemblies
