ABSTRACT:
A hermetically-sealed actuator for a rotary valve is provided in which a first camming member is operative to move a stem axially, axial movement of the stem, in turn, producing rotation of a second rotary cam mamber that is operatively connected to rotate a valve spindle, the axially movable stem being hermetically sealed by a bellows mechanism, thus hermetically isolating the second camming member from the first camming member.
