Diaphragm in-line valve VM 16 / Vacuubrand

Diaphragm in-line valve VM 16 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.
The VS und VS C series valves from VACUUBRAND are butterfly-type valves.
The VS und VS C series valves from VACUUBRAND are butterfly-type valves. A circular valve plate with a sealing ring on the circumference rotates around an axis at right angle to the valve axis. As a result, the valves leave virtually the entire cross section free, offering very good conductance.
• materials with high chemical resistance
• high conductance, low leakage rate
• flow control possible
• gas-tight against atmosphere in both directions
