All valves are conical in design, the valve cross-sections are tailored to the respective scales. They are excellent air-tight, providing precise and reliable action. The forces are transmitted through extremely durable ball joints. Other mechanisms like string mechanism with horns are possible. All models are delivered with spiral spring key system. However special versions are available on request.
For all flugelhorn and trumpet models we also offer adjustable closed torsional spring key system.
