The Finke valve system is something special, not only because of the light weight. In the early 70's when Helmut Finke designed his first triple horn he decided to take the challenge for a new valve system. Traditional rotary valves are tapered and made out of brass. The finishing manufacture process is the lapping of the the rotors into the casings. The disadvantage is the high weight and the reduced possibility of replacing parts, when needed.
In the past few years some manufactures reduced the instrument`s weight with making the diameter and the sealing surface of the rotor smaller and to cut down the wall thickness on the casings. This makes the valves more sensitive against damages.
Finke decided to replace the brass against modern synthetics, this made a great difference in weight. The rotors are no longer conical and the bearing plates on both casing sides are tapped in and hold in position by a srew ring. This system allows to replace components, if necessairy, and to remove valves for cleaning, easily.
Since the first horns with these valves were made in the early 70's we have improved the new design constantly. We have kept a close eye to new developed synthetics and a few times have changed to improven materials. The nowadays used synthetic is acid resitance, has a very high temperature melting point and is not absorbing any water like the first used materials did.
This high tech material is also used in aircraft industries to replace metal. The rotors are seated on a stainless steel shaft in the center of the rotor. Due to small tolerances, we manufacture very precise valves, which also improve the playing abilities of the instrument. The reduced mass and the short action mechanicsm gives a complete new feel to playing.
