Diaphragm valve<br />
Diaphragm valves VM<br />
VM series valves are hand-operated diaphragm valves. They are used as isolation valves, air-admittance valves or<br />
manual-control valves. By the rotation of the wheel, a flexible PTFE diaphragm will be moved and be pressed against<br />
the stainless steel seating or be removed from it (valve closes or is open more or less). The gas-contacting parts are<br />
made of materials such as stainless steel and PTFE, which offer a good resistance to corrosive gases and vapors.<br />
