An inflatable butterfly valve, also known as an air-operated butterfly valve, is a type of valve that uses air pressure to operate. The valve consists of a butterfly disc mounted on a shaft inside a valve body. The disc is connected to an inflatable seal or bladder that is inflated or deflated with air pressure to open or close the valve. When the seal is inflated, it presses against the valve body and closes off the flow of fluid. The disc rotates when the seal is deflated to allow fluid to flow through the valve.
Inflatable butterfly valves are commonly used in applications requiring a tight, leak-proof seal, such as in water treatment, wastewater treatment, and chemical processing. They are often used when other valves may not provide a tight enough seal or may be prone to leakage. Inflatable butterfly valves are also useful in situations where manual or mechanical operation of valves is not feasible, such as in remote locations or hazardous environments. The air-operated system allows for easy and remote operation of the valve, making it a popular choice in many industries.
The inflatable seat butterfly valve is an innovative and reliable solution for controlling and regulating fluid flow in various industrial applications.
