4-offsetdesign principle

Created for extremes

Thanks to the innovative design principle, even extreme temperatures from -270° C to +800° C are no problem.
Quadax® butterfly valves are ideal solutions for demanding 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®– Kvalves meet even the highest tightness requirements 100%.

Made in Germany

We produce our butterfly valves from the highest quality materials on modern 5-axis machining centres. Entirely in Germany.


4-offset-eccentric quadax® Butterfly Valve


  • 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-offsetbutterfly valve


  • Wear due to friction
  • More leaks (especially under extreme conditions)
  • maintenance vulnerable

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.
