Total price
The spool governs how the axis behaves in mid position, which makes it the first selection criterion. In this size 25 valve, symbol E works with 325 l/min nominal flow and a fully external pilot circuit.
Benefits
- Spool symbol E with three switching positions and four ports
- 325 l/min nominal flow against a valve maximum of 870 l/min
- External pilot feed and pilot return keep control behaviour independent of operating pressure up to 350 bar
- 4-20 mA interface, robust even over long cable routes
- Mass 20.62 kg, subplate mounting to ISO 4401-08-08-0-05
