The first of these types was the Stölzel valve, bearing the name of its inventor Heinrich Stölzel, who first applied these valves to the French horn in 1814. Until that point, there had been no successful valve design, and horn players had to stop off the bell of the instrument, greatly compromising tone quality to achieve a partial chromatic scale.
In the 1980s, many U.S. production engine remanufacturers began reaming valve guides, rather than replacing them, as part of their remanufacturing process. They found that by reaming all the valve guides in a head to one standard size (typically 0.008 in. diametrically oversized), and installing remanufactured engine valves having stems that are also oversized, a typical engine head can be ...
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.

The first piston valve instruments were developed just after the start of the 19th century. The Stölzel valve (invented by Heinrich Stölzel in 1814) was an early variety. In the mid 19th century the Vienna valve was an improved design. However many professional musicians preferred rotary valves for quicker, more reliable action, until better ...
The present-day mellophone has three valves, operated with the right hand (1- and 2- valve mellophone bugles have been used in the past). Mellophone fingerings are the same as the trumpet. [3] It is typically pitched lower, in the key of F or E ♭. The overtone series of the F mellophone is an octave above that of the F horn.
A piston valve is a device used to control the motion of a fluid or gas along a tube or pipe by means of the linear motion of a piston within a chamber or cylinder. [1] Examples of piston valves are: The valves used in many brass instruments; The valves used for pneumatic propulsion; The valves used in many stationary steam engines and steam ...
