Total price
A smaller nominal flow makes control finer, a current signal makes it robust. This variant combines the two and works with 220 l/min, a 4-20 mA interface and spool symbol E.
Benefits
- 220 l/min nominal flow, finer command resolution than the 325 l/min variant
- 4-20 mA current command, unaffected by cable resistance and pick-up
- Internal pilot feed and pilot return, no additional drillings in the manifold
- Spool symbol E, operating pressure up to 350 bar, valve maximum 870 l/min
- Mass 20.76 kg, 7-pole connector (6 + PE) to EN 175201-804
