- Both Flanged Ends
- Wafer Type Ends
- Lug Type Ends
- Butt Welded Types Ends
Wafer Butterfly Valve
Wafer concentric butterfly valve features a cartridge-type seat, streamlined disc, and strong stem-to-disc connection for easy use in industrial applications such as food and beverage, pulp and paper, chemical, mining, water treatment, power plants, etc.
Lug Butterfly Valve
This type of design has lugs attached to the valve body. Dead-end connections are the common uses for this type of butterfly valve.
What is API 609 A Butterfly Valve?
API 609 is the American design standard for butterfly valves divided into Categories A and B.
Category A valves are “concentric” type. Also known as rubber-lined butterfly valves. These are popular in low-pressure systems (Class 150 or less), relatively lower cycle life, and rubber liners are also good for abrasive slurry services.
Category B valves are “offset” type, meaning the shaft is offset from the disc so that they can handle higher differential pressures. Most offset types cause the disc to rotate freely from the seat after a few degrees of rotation, which minimizes seat wear and increases valve cycle life. The offset type can have rubber, polymer (PTFE or other), metal &graphite, or even metal seats. Lots of variety makes these suitable for various temperatures and pressures.
