AS-Schneider’s “technically leakproof” solution
AS-Schneider introduces its tried and tested bellows sealed valves for very hazardous media that even a minimal leak rate can be too great.
“Technically leakproof” bellows valves
With very dangerous media, even the minimal ISO FE-Series leak rate can be too high. In cases like these, you can, however, use tried and tested AS-Schneider bellows valves.To move the valve stem upwards and downwards on a leak-free basis, a multi-layer, metal bellow is used that is firmly attached on the one side to the stem and on the other side is firmly welded to the housing.
