Valve Travel in Player Piano Action
By Herb Ziegler

Is the valve clearance on a single-valve Standard Action the same
as the secondary valves on a two-valve unit?

Herb Ziegler

 [ I've been told that the valve travel of a single-valve system is
 [ typically .035 to .038 inch, regardless of the maker.  The travel
 [ of the secondary valve in a double-valve system may be greater.
