Metal Diaphragm Valves
Depending on design, these valves are specifically suitable for highly-pure to heavily contaminated liquid and gaseous, inert and corrosive media.
Just as classical control valves, diaphragm valves also have good control properties, especially for media which are contaminated or contain particles.
The major areas of use are processes in a vast range of different industrial applications.
