Diaphragm valve in action
Diaphragm in-line valve VM 25
VM series valves are hand-operated diaphragm valves. They are used, e.g., as isolation valves, air-admittance valves or manual-control valves. By rotation of the wheel a flexible PTFE diaphragm is moved and pressed against the stainless steel seating or removed from it, closing and opening the valve, respectively. The gas-contacting parts are made of stainless steel and PTFE offering a good resistance to corrosive gases and vapors.Technical data and graphs
