DN 50-1200 mm / 2" - 48"

Design Features

Swiss product
Built up on the principle of concentric soft seated butterfly valves
One piece disc and shaft
Body with 2 components epoxy coating
PFA coated disc with TFM liner of min. 3 mm thickness
Maintenance free bearings of the shaft
By using the same radius of the liner and of the disc at the intersection to the shaft, a perfect shapening is guaranteed for a fully tight valve over a long lifetime.
A large tightness surface of the liner provides a secure sealing to the counter flange.
Elastic backliners make the valve gas tight
A tight sealing between the liner and the disc is ensured by a compression package based on the principle of a floating ring seal
