Abstract
A fluid control valve assembly for controlling the flow of fluid passing through a fluid passageway defined in a valve body and having an inlet end and an outlet end. A bellows formed of low tackiness material has fixed one end wall secured to the valve body and the other movable end wall connected to a valve stem. The valve stem is actuated by an actuator to move the other movable end wall of the bellows between a closed position in which the other movable end wall is brought into direct contact with a valve seat located in the fluid passageway and an open position in which the other movable end wall is brought out of engagement with the valve seat.
