The three main types of butterfly valves are
Concentric Butterfly Valve: Features a centrally mounted disc that rotates around a shaft. It's commonly used in low-pressure applications and has a simple design.
Eccentric Butterfly Valve: The disc is offset from the center of the valve body, allowing for better sealing and reduced wear. It's often used in higher-pressure applications and provides better flow control.
Double Eccentric Butterfly Valve: Also known as a high-performance valve, it has two offsets (the disc and shaft) which enhance sealing and minimize friction. This type is suitable for high-pressure and high-temperature applications.
