Metal seated butterfly valve classification

Based on the connection there are different types of metal seated butterfly valve.
Wafer Type metal seated butterfly valve: The wafer type metal seated butterfly valves was built to keep a tight sealing, protecting against bi-directional pressure differentials, to prevent any backflow in devices that were built for uni-directional flow. This is done by the use of a tightly fitted cap, such as an O-ring, gasket, precisely machined, along with a smooth valve face on the downstream and upstream parts of the valve.
Lug Type metal seated butterfly valve: The lug type 
metal seated butterfly valve configuration is similar to the 3-piece ball valve in which one end of the pipeline can be replaced without impacting the other side of the valve. This can be achieved with threaded inserts, flanges, and two sets of lugs (bolts) that do not use nuts so each flange has its bolts. It is also important to remember that you do not need to shut down the whole device to inspect, clean, repair, or replace the lug butterfly valve.
Flanged End Type metal seated butterfly valve: The flanged type 
metal seated butterfly valve has a flange at both ends of the valve to be attached with pipe flanges. This type of end connection is used for the very large size of butterfly valve.
Welded End Type metal seated butterfly valve: The welded end type 
metal seated butterfly valve is used where system is under very high pressure. These types are generally used for small size butterfly valves.
