DescriptionYellow brass valve and wrap tubing with nickel silver and brass ferrules, nickel silver trim. Yellow brass knurled nut for slide receiver. Yellow brass knurled nuts for bell brace connections. Nickel silver valve linkage. Lacquer finish. Straight gooseneck with free-flow rotary valve that diverts flow to valve wrap. Valve wrap is open in design with one full turn at bow, one ¾ turn returning to gooseneck, and one bend leaving valve. Valve wrap tuning slide in rearward wrap bow. One free-flow valve produced by Rene Hagmann in Geneve, in gooseneck rearward of main bell brace. Mechanical linkage has pivot point attached to slide receiver instead of main bell brace. Valve has tubes brazed inside a hollow rotating core, unlike a traditional rotor valve which is bored out of a solid brass core.
This is one of the two valve options offered with the E700 series, known as “EVH”, H referencing the Hagmann valve. The Hagmann valve was first introduced in 1990 and Courtois, under the direction of Jacques Gaudet was the first company to contract production of these valves for use on a commercial scale.
