What would happen if you combined the best aspects of both pistons and rotors in one valve?
Building upon these great characteristics, the MAW Valve goes one step further. Many prior pistons, compromised by manufacturing irregularities (bumps) in the windways, are inherently distortive. Bumps alter sound waves. To avoid this, the MAW Valve opens the middle windway to create a smooth rotor-like passage. Both of the windways above and below this middle passage are now smooth and round inside the MAW Valve.
The geometry of the patented MAW Valve advances the playing characteristics of a horn. With the MAW Valve, sound waves traveling through the instrument are less disrupted. Playing is easier. There is a fuller sound with less effort. Notes tend to be more stable with increased clarity. The MAW valve combines the best qualities of pistons and rotors.

I have been using the MAW Valves in my Meinl Weston 5450 for a couple months now and the playability of the instrument is dramatically simplified! Slurring across partials with a valve change is near seamless with these new valves. They have definitely made life on the tuba much easier.
In 2010, Martin Wilk transformed my original Yorkbrunner valves into MAW valves. Notes that were woofy became the best notes on the horn. Extreme pitch problems were reduced to manageable ones. Articulation, slurring, clarity of tone and projection all improved. I have MAW replacement valves in my Nirschl now, made by Meinlschmidt - a valve-maker known for the highest quality available.

I love your MAW valves. Since we last talked, I have played quite a bit of repertoire on the tuba, particularly Mahler 6 (plus on tour in Europe). There is a huge difference. It is actually a rather inexpensive modification for the results you get.
