Rotary engines do not have valves. They have rotors that are triangular shaped that spin in a circle around the eccentric shaft alongside the housing wall. The fuel squirts into the chamber made by the triangular shape and the housing wall, this is where the exhaust port and the spark plugs are located, as the rotor spins it builds pressure in the chamber and ignites the fuel spinning the rotor.
I'm no brass instrument, but rotary valves are used for several instruments. French horns all seem to have them. They're pretty common on tubas as well. There are even some rotary valve trumpets out there. I don't know, though, anything about the advantages and/or disadvantages of rotary valves as opposed to the piston valves that seem to be more common for most brass instruments.
A rack and pinion, cam, crank, and screw can do that.
Rotary trumpets, meaning they use rotary valves (like on a French horn) instead of piston valves.
A Plug Valve is a Globe Valve. Very generally speaking there are two major catagories of Industrial Process Control Valves, Sliding Stem and Rotary. Globe Bodies valves fall into the category of Sliding Stem Valves. Butterfly and Ball valves fall into the category of Rotary valves. However there are what is referred as Rotary Plug Valves, whereby a partial sphere has a shaft eccentrically mounted, that rotates into and out of a metal or composition seat acting as a plug. Most plug valves are sliding stem.
Neither it is a woodwind instrument and has keys. Do you mean the soprano cornet? This is a brass instrument which has piston valves.
French horns do have valves, but not the same kind trumpets use. Trumpets use pistons, and french horns use Rotary Valves. However, a marching french horn, a melophone, does have piston valves.

Normally they're called valves. There are some trumpets out there with rotary valves, which are often just called keys.
