Probably Crane and Bray fill the other 2 spots.
There have to be at least a spazillion companies making Butterfly valves.

Or are you wanting three universal butterfly bidders for all applications anywhere in the world?

Aside from Vanessa triple offset and Keystone (now Tyco) K-LOK butterfly valves, the other names that readily surface in my mind are Velan, Unicom (high performance type from S Korea) and Flow Serve.

The Far-East / Pacific Rim recent 'explosion' of manufacturer's have yet to really get their heads around TOBV's, both in 'design' and especially when it comes to 'exotics' in material spec's, but rest-assured, they WILL get there, and probably very quickly.
When it comes to double-offset and standard 'rubber lined' butterfly's.. the world is literally one's oyster ... there are a multitude of companies manufacturing and distributing - it all comes down to the old adage, " Ye pay for what ye get, my son "
Its easy to get a hold of really cheap and cheerful equipment ( as it is in virtually every sphere of valves ) but some of them wouldn't hold back snow, never mind any form of pressure containment.
To summarise - its horses for courses.. consider your application and the media to which you wish to subject the valve to, with a thought being given to all the usual temperature / pressure / chemical resistance criteria, and select something thats "fit for purpose"
Cheers.

ADAMS Valves from Herne Germany patented the very concept that EVERY SINGLE other TOV manufacturer currently copies today.
Are you really GOD of valves???

2) the double eccentric butterfly valve in which the sealing elements are the seat (at least in stainlees steel) and the seal ring (in rubber or in TEFLON in the case of the High Performance)
3) the tripple eccentric metal to metal seated valves.
In this case, from my point of view, it is wrong called this kind of valve butterfly. In fact the sealing elements are the seats in metal and the seal ring in metal. This is possible because of the third eccentricity. This kind of valves are now becoming the more specified valve to be used on the process.
Talking about the tipple eccentric metal seatd valve there are now three main suppliers in the world: ORTON (Italy), Tyco-Vanessa (Italy) and Adams.
From my point of view Orton and Vanessa are very good suppliers while Adams has commmitted too many mistakes (mainly in Ras Laffan Project in Qatar) in the past and now is not so reliable.

Other suppliers such as Zwick make tripple offset butterfly valves. Each supplier makes mistakes. Many mistakes are made by the valve peddler who mis-applies a valve; often to sell something from stock. We all get upset with suppliers for mistakes.

Common mistakes:
elastomers incompatible with the fluid
floating balls sold for bi-directional applications
actuator sized for air pressure greater
position switches and solenoid valves installed without terminal strips or identification
failure to segregate terminal for - intrinsically safe; or for shutdown system controlling the solenoid and DCS monitoring position; or for different 24 Vdc/120 Vac signals, etc.
closing time too slow for large valves in gas service
closing time too fast for smaller valves in liquid service
