Total price
A shared tank line builds up back pressure that slows the pilot stage, and a dedicated pilot drain protects against exactly that. This size 25 valve takes pilot oil internally, discharges it externally and processes the ±10 V command value at 350 l/min nominal flow.
Benefits
- Internal pilot oil supply with external pilot oil return through the Y port
- ±10 V command value, 24 VDC supply, on-board electronics at the valve
- 350 l/min nominal flow, up to 870 l/min possible across the valve
- Spool symbol E1, linear characteristic curve with a fine control range
- NBR seals, operating pressure up to 350 bar, weight 17.83 kg
