RE: Large Butterfly Valves Liner
Depending on how large is large, it will be far easier to replace the seat if worn instead of the complete valve (and for sure cheaper). On small valves, typical 2"-4", it would make little sense to replace the seat as it most likely will be cheaper to replace the complete butterfly valve (if it's a low cost trim, typical cast iron body and 316 stem /disc/buna n seat). We use eccentric butterfly valves for throttling (low pressure / high flow application) and would not recommend the use of vulcanized seats as the seat typically would be replaced each 3-4 years.

AWWA valves frequently have bonded seats. AWWA valves are designed by a committee to be mediocre and interchangeable.
Name-Brand valves including, but not limited to Bray and Tyco-Keystone have replaceble liners that lock into the body and provide the gasket surface as well as the seat.
