The Hagmann Free-Flow Valve is a trademarked brass instrument valve design developed by Swiss musician and instrument technician René Hagmann, first introduced for trombone F attachments in 1990. His intention was to address some of the geometrical limitations of the regular rotary valve, as well as the reliability and maintenance issues of the popular Thayer axial flow valve that arise from its relatively complex design.
