Sanitary butterfly valves with flanged ends - Overview, Working Principle & Technical Parameters

Sanitary butterfly valves with flanged ends refers to a clean-type sanitary butterfly valve, which adopts flange connection for easy installation and disassembly. It is widely used in various fields such as beer, beverage, dairy products, fruit juice, pharmaceuticals, and biological engineering.

Working Principle of Sanitary butterfly valves with flanged ends

1. Sanitary butterfly valves with flanged endss with flanged ends are divided into manual type, pneumatic type, intelligent pneumatic type and electric actuated type;

2. Manual butterfly valves are equipped with round-head pull handle, square-head pull handle, 12-position plastic handle and 12-position stainless steel handle. The butterfly valve can be matched with stainless steel pneumatic actuator, aluminum pneumatic actuator, intelligent pneumatic actuator and electric actuator;

3. The opening and closing range is 0~90 degrees, which can be fixed at every 15 degrees position, with adjustability, and the opening and closing are rapid and easy to operate;

4. Both the rubber sealing ring and valve plate of the butterfly valve adopt imported parts, ensuring the performance and service life of the butterfly valve.
