Three body types in butterfly valves
2012-08-23
The butterfly valve is widely used in water pipeline system, foodstuff, beverage, pharmaceutics, boiler, oil refining, chemical machinery industries, chemical and petrochemical processing, power generating plants, pulp and paper manufacturing processing, desalination, steelmaking, coal and mining industries.
Butterfly valves can come in three body types, lugged,wafer and flanged. Wafer
style valves are more common. They are typically installed between two flanges
using bolts or studs and nuts. Lug style valves are also installed between two
flanges but with a separate set of bolts for each flange. The lugged style setup
makes it possible to remove one side of the piping while the other remains
intact.
