A rotary valve flugelhorn. The flugelhorn is generally pitched in B♭, like most trumpets and cornets. It usually has three piston valves and employs the same fingering system as other brass instruments, although four-valve versions and rotary-valve versions also exist. It can therefore be played by trumpet and cornet players, although it has ...
Thayer axial flow valve on a tenor trombone. The axial flow valve, or Thayer valve, is a brass instrument valve design patented in 1978 by Orla Ed Thayer. [1] Designed with assistance from Zigmant Kanstul, it was originally intended to replace the traditional rotary valve on the French horn, but instead revolutionized the design of trombone valve attachments.

Modern valve brass instruments not using either rotary or Vienna valves use this type of valve in a set of three configured to lower the instrument by two, one, and three half-steps respectively, which in combination lower the instrument pitch by up to a tritone. Some instruments (e.g. the tuba and euphonium) add a fourth valve that further ...
Second, if "the instrument has been previously restored and most ephemeral has been lost."

[1] The common stopcock is the simplest form of rotary valve. Rotary valves have been applied in numerous applications, including:

Initially opened as a repair shop, the company expanded after World War II to instrument manufacture. In 1946, Getzen produced its first trombones. In 1947, Getzen started producing trumpets and cornets as well ...
The type of rotary valve I am looking for is not for a musical instrument. The rotary valve I am interested in is used in the Petrochemical industry. I would imagine the concept is similar, but we need a more discriptive illustration showing the mechanics of the operation. See: www.fielddevices.com item: Positioners
