5 Figure HPA BUTTERFLY VALVES Double Off-Set Design centerline of the valve stem, putting the stem behind the sealing surface. Since the stem does not penetrate the sealing surface, there is a complete, uninterrupted, 360 seat seal. The second offset is between the centerline of the valve stem and the centerline of the valve port. This double-offset creates an eccentric seating action that reduces seat wear and torque. The disc cams into the seat for a bubble tight shut-off. The cam action is improved by the conical angle of the valve disc. DOUBLE OFF-SET Centerline of valve port Centerline of stem OFF-SET #2 Centerline of seal OFF-SET #1 Centerline of stem CAM ACTION The disc pulls away from the seat, reducing wear and torque. CONICAL ANGLED DISC The disc edges are angled as if cut from a cone. This angle improves the cam action of the valve.
