design principle
Created for extremes
Thanks to our innovative design principle, even extreme temperatures from -270° C to +800° C are no problem.
Quadax® butterfly valves are the ideal solution for customers with the highest demands on tightness – for extreme applications and temperature ranges.
100% tight
Thanks to their 4-offset design and state-of-the-art manufacturing technology, Quadax®valves meet even the highest tightness requirements 100% of the time.
Made in Germany
We produce our butterfly valves from the highest quality materials on modern 5-axis machining centers. Entirely in Germany.
The
comparison
4-offset-eccentric Quadax® butterfly valve
SUMMARY:
- Frictionless
- Higher KV values
- Higher tightness (even in the most extreme conditions)
The 4-offset butterfly valve has an elliptical output cone. The cut at a specific angle results in a rounder and thus larger sealing seat.
Conventional 3-offset
butterfly valve
SUMMARY:
- Wear due to friction
- More leaks (especially under extreme conditions)
- Maintenance vulnerabilities
The sealing seat has a conical shape. The tip of the cone is offset from the middle of the pipe to the outer edge. A round cone results in a tight, elliptical sealing seat in the housing.
