ABSTRACT:
By providing direct activation of the ball element by the cam lobe of a cam member in a ball valve, instead of utilizing additional links between the cam lobe and the ball member, positive valve action is achieved, the cost and complexity of the valve is decreased and the problems which arise from corrosion and sediment accumulation in linking elements are avoided.
