Principle Of Operation
The SDF Triple Offset Butterfly Valve provides a bi-directional bubble tight shut-off. This geometry ensures that the disc seal contacts the body seat only at the final shut-off position without rubbing or galling, providing a torque generated resilient seal with sufficientwedgingto ensure a uniform seal contact.
THE TRIPLE OFFSET GEOMETRY
OFFSET 1 The shaft is offset behind the seat axis to allow complete sealing contact around the entire seat.
OFFSET 2 The shaft centerline is offset from the pipe and valve  which provides interference free opening and closing of the valve.
OFFSET 3 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.
