Wafer Style
Wafer style butterfly valves are sandwich mounted between flanges and fixed in place with thru bolts. The body may or may not have non threaded lugs that are used only to help to align the butterfly concentrically when installing – because these lugs are not threaded the wafer valve can be ‘universal’ and suitable to be mounted between a variety of different flange classes. Wafer style butterfly valves are not suitable for end of line applications.
