Our expert knows the applications of industrial valves and will be glad to advise you!
Diaphragm valves
Diaphragm valves control or interrupt the flow of liquids in industrial processes. Their flexible diaphragm regulates the flow through a pipe. Due to their high corrosion resistance, diaphragm valves are used in many industries for handling aggressive, abrasive or corrosive substances. The valve selection depends, among other things, on the substance, pressure and temperature involved.
Our diaphragm valves can be customized and are available in our online shop.
