Abstract
A valve actuator mechanism for supplying a selectively adjustable close-off force to an associated valve. The mechanism comprises a means for urging the valve plunger into engagement with the valve seat with a predetermined initial force and resistive means for generating a resistive force such that the close-off force is less than the initial by a predetermined amount. The resistive force can be selectively adjusted also.
