GEMÜ metal industrial diaphragm valves

For industrial applications

GEMÜ metal industrial diaphragm valves

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.

Application example: Bor-dekontaminering

Boron Decontamination
According to the World Health Organisation a boron content of >0.5 mg/l in drinking water is harmful. In addition, it has been shown that too high a boron content in water used for the irrigation of plants can also be harmful to humans and animals when these are eaten. Boron
