The world’s leading modular PTFE-lined butterfly valve, built to the highest quality standards for safe handling of aggressive media.
Safe handling of corrosive media thanks to a unique sealing system
A regulating pressure package guarantees the specified contact pressure and maximum tightness over the entire lifetime of the equipment
Specially designed for use with aggressive media such as chlorine gas, hydrofluoric acid and sulfuric acid
Above-average overall performance thanks to a technically proven but constantly improved sealing system
Design Advantages of Flowrates PTFE Butterfly Valves
Reduced friction and increased service life thanks to spherical design elements
Rounded and polished sealing surfaces of the disc reduce the torque and allow the use of smaller and cheaper actuators
The one-piece valve disc, precisely dimensioned to within tenths of a millimeter, always remains securely anchored in the valve
Injection molded elastomer inserts with a complex design ensure maximum tightness over an increased service life
Body Types and Available Configurations
Wafer DN50-300 (Can be made from DN350 to DN1200 with lug body and unthreaded holes.)
Industrial Applications of PTFE Coated Valves
Butterly valve lined with PTFE/PFA or mod. PTFE/PFA for high chemical demands. To shut off and control corrosive and abrasive liquids or gases.
