The valve meters direction as well as volume to spool symbol E at 220 l/min nominal flow, and at 350 bar the flow limit is 870 l/min. The command value is fed as a 4...20 mA current, which secures signal transmission over longer distances.
Benefits
- 220 l/min nominal flow at 350 bar, flow limit 870 l/min
- Current command 4...20 mA, sturdy against interference on long cable runs
- Internal pilot oil supply, external pilot drain against back pressure in the return
- Spool symbol E, 3 switching positions, concealed manual override
- FKM seals for HL fluid, UKCA to SI2016/1091, mass of 20.58 kg
