Areas of application and industrial sectors
Depending on the version, GEMÜ diaphragm valves are particularly suitable for use with both inert and corrosive media. They can be used to control and/or regulate heavily contaminated liquid and gaseous media or media containing tiny particles. The major areas of use are processes in the widest range of general industrial applications. The valves can also be equipped with numerous accessories, such as seal adjusters and stroke limiters, manual overrides, proximity switches, optical position indicators, electrical position indicators, combi switchboxes, pilot valves, as well as positioners and process controllers.
