The specially machined inner contour of the gasket has a crucial impact on the tightness achieved by the valve and can be produced with high-quality surface finishes to meet customer specifications. A wide range of stainless steels and special alloys are available as metallic materials, which can be combined with proven soft materials such as graphite, PTFE and mica.
For critical and sensitive applications, such as use in oxygen lines, graphite-based butterfly valve seals can be manufactured with the innovative LE-SAFE technology without the use of adhesives. Furthermore, only pure graphite materials from a BAM-tested single batch are used, as well as metal materials that have been recommended for oxygen applications, such as 1.4401/1.4404, 1.4828.
