Behaviour in mid position and resolution around zero determine how precisely a large axis starts. This size 25 proportional valve therefore combines spool symbol E1 with a linear characteristic curve including a fine control range, passes 220 l/min nominal flow and processes the ±10 V command value in its on-board electronics.
Benefits
- Spool symbol E1 with a linear characteristic curve and fine control range
- 220 l/min nominal flow, up to 870 l/min permitted across the valve
- ±10 V command value, 24 VDC supply, no external amplifier card needed
- Internal pilot oil supply with external pilot oil return
- NBR seals, operating pressure up to 350 bar, weight 17.8 kg
