This popular valve is also known as a high performance butterfly valve. This valve has two stems offset from the center. This creates a cam action during the application's process.

1^st offset: The axis of the shaft is behind the centerline of the sealing point of the disc to seat.
2^nd offset: The axis of the shaft is eccentric to the center of the valve/pipe line.

The double offset butterfly valve is generally used in:

Power generation
Pulp and paper
HVAC
Chemical
Oil and gas
Water and wastewater treatment
Shipbuilding

Double offset butterfly valves are available in higher pressures than the zero offset style. The double offset is up to ANSI Class 600 rating in carbon steel, stainless steel, Hastelloy and other body material, with variations of Teflon seats and also Fire Safe design with metal back up seats.
