Largest compact proportional valve in the range
The DN20 model represents the upper limit of the compact AUSYFLUX proportional valve range.
Compared to smaller models:
→ DN1 → ultra high pressure / low flow
→ DN6 → mid flow
→ DN12 → high flow
→ DN20 → maximum flow (compact range)
For applications requiring even larger sizes or specialist performance, see our high-performance proportional control valves (DN25 and above).
