Valves minimize air loss when playing blow or draw notes. If both reeds of a corresponding reed pair are equipped with valves, the possibilities of bending the notes is very limited. If a valve is only closing the lower tuned reed of the pair then bending notes remains possible (= half-valving).
On a fully valved harmonica air-loss is minimized, bendability is restricted very much. The valve set provided is suited for one full-valved instrument (+ set of spare valves) or three half-valved instruments.
On half-valved Richter instruments the valves(=windsavers) must be attached onto the draw plate of 1-6 (the valve is situated on the inside of hole) and onto the blow plate of 7-10 (valve is situated on outside of upper plate then). This leads to better air-tightness of the instrument - bending notes are still playable, whereas overbendings can not be played anymore. With half-valving you will get the full chromatic scale with bending instead of using overblows.
Please use very little amounts of a suited glue, e.g. the >original SEYDEL valve glue. If you use superglue (use gel, no fluid!l) please let it dry out 100% as the solvent used in these glues are harmful.
