Total price
With a voltage command and a separate pilot circuit, this build of the 4WRTE25V1-350L covers classic plant engineering, where the valve electronics take the place of an amplifier card.
Benefits
- 350 l/min nominal flow covers continuous duty, the reserve up to 870 l/min absorbs rapid traverse peaks
- Up to 350 bar operating pressure, suitable for press circuits running at high system pressure
- Spool Symbol V1 with a linear characteristic, 3 switching positions
- External pilot oil supply and external pilot oil return, pilot operated design
- The control electronics sit on the valve body, position feedback makes a separate amplifier card unnecessary

Applications
The valve is used when retrofitting older installations in which an external amplifier card controlled spool position. Pilot supply and pilot return stay external and therefore unchanged. At 17.86 kg with an ISO 4401-08-08-0-05 interface it fits the existing manifold.
