PTFE Valves

PTFE-lined shut-off and control valves are designed for use in chemically aggressive leaches and acids. The minimum 3 mm thick lining comprising virgin PTFE ensures optimal permeation protection. In conjunction with the double shaft seal, this series offers maximum operational safety, even with corrosive and toxic media.
