Zero offset butterfly valves are used in basic and specialty liquid and gas applications up to 200 PSI and up to 400 deg F. The zero offset butterfly valve can handle chemicals, coatings, food, some solids, and abrasive applications.

Triple offset valves are classified as zero leak valves while double offset or high performance valves are classified as Class VI shut off valves. The type of offset used in a butterfly valve depends on the specific application and the desired performance characteristics of the valve.

In the oil and gas industry, A triple offset butterfly valve has its optimum role where a vacuum seal is required in high-temperature conditions. A triple offset butterfly valve has three separate offsets from the center that makes it special.

The double-offset butterfly valve is a valve that has 2 offset compare with the concentric butterfly valve. The first offset is the shaft located not in the center of the disk but located on slightly behind the disc.

5 days ago · The double-offset butterfly valve, often called a high-performance butterfly valve, features two key offsets relative to the valve body’s center. The first one is the shaft axis, which is offset from the centerline of the disc’s seat and the body seal.

Zero offset butterfly valves offer a cost-effective solution for low-demand applications, while double offset valves provide improved performance for medium-range needs. For critical and demanding applications, triple offset butterfly valves deliver unmatched sealing performance and …

In this article, you will learn the benefits of a triple offset butterfly valve, see a sample drawing, and realize its benefits vs other types of butterfly valves. Triple offset, as the name implies, uses three separate offsets to achieve a bubble-tight shut-off.

Learn about types of butterfly valve that used in piping. Lug type, wafer type, double offset and triple offset butterfly valves. A complete guide.

In a standard butterfly valve, the disc (the ‘butterfly’) is positioned directly in the center of the pipe bore, leading to a certain degree of friction and wear when the valve is opened or closed. However, in a double offset butterfly valve, the disc is intentionally offset from the centerline of the pipe bore and the seal.

Double Offset Butterfly Valve. The double-offset butterfly valve’s stem has two offsets from centerlines within the valve. The first offset is from the centerline of the seat seal to the centerline of the shaft. The second offset is from the centerline of the bore to the centre of the shaft.
