Description
In rough plants disturbances arrive from two directions, from the hydraulic circuit and from the signal cable. This size 25 version answers both with external pilot oil supply, external pilot oil return and a 4...20 mA current command value, while metering 350 l/min nominal flow with a fine control range.
Benefits
- External pilot oil supply and external pilot oil return
- 4...20 mA command value, resistant to voltage drop on the signal line
- 350 l/min nominal flow, maximum flow 870 l/min
- Spool symbol W8, linear characteristic curve with a fine control range
- NBR seals, operating pressure up to 350 bar, weight 17.92 kg
Applications
The valve works in rolling mills, foundries and large presses with an unsteady supply network. Internal spool position feedback holds the spool in place under changing load. Subplate mounting to ISO 4401-08-08-0-05 is standard for size 25.
