Diaphragm valves | Choosing the right valve
Diaphragm valves are mainly used in hygienic and aseptic processes, i.e. when the circulating fluid must be isolated from any potential contamination. These valves operate primarily in open/closed mode, although in some cases they can be used for fluid regulation. In the open position, these valves are called "full flow" and create almost no pressure drops as the closing diaphragm completely clears the fluid flow. The sealing tightness of these valves is...
