ABSTRACT:
The valve member of a solenoid operated valve adapted to be mounted within the windchest of a pipe organ for opening and closing an aperture leading to a pipe is provided with a circular projection on one surface thereof adapted to project into the circular aperture with minimal clearance to reduce the amount of air flow through the aperture should the main portion of the valve member separate slightly from the seat surrounding the aperture as a result of bounce during a valve closing operation.
