The Triple-Offset Geometry
OFFSET 1: The shaft is offset behind the seat axis to allow complete sealing contact around the entire seat.
OFFSET2: The shaft centerline is offset from the pipe and valve which provides interference free opening and closing of the valve.
OFFSET3: The seat cone axis is offset from the shaft centerline to eliminate friction during closing and opening and to achieve uniform compressive sealing around the entire seat.
