Do you want to improve your sound or gaming experience? You may have already noticed that there are different valves on trombones. There is the classic rotor valve, the Thayer valve and the Hagmann valve. Below I would like to explain the differences to you:

Traditional rotary valve:

Rotary valve of a Conn 88h

Thayer valve:

Axial valve on a Bach 42AF

Hagmann valve:

Hagmann valve on a Bach 42A

These 3 valve types are the predominant designs. Bach’s “Infinity” axial valve, for example, is based on Thayer’s design. The Bach Miller valve or the Shires Tru-Bore are basically variations of the Hagmann design.
Each design has its advantages and disadvantages. Consequently, advocates and opponents in all areas of music. What suits you?
