Sanitary butterfly valve fittings have a variety of connection methods to meet the needs of different industries and application scenarios. Here are some common connection methods: 

 1. Clamp Connection: 

 Use the clamp to quickly connect the valve to the pipe. 

 Installation and disassembly are very convenient, and no tools are required. 

 No dead angle design, easy to clean and disinfect. 

 It is widely used in food, beverage, pharmaceutical, cosmetics and other industries, and is suitable for occasions that require frequent disassembly and cleaning. 

 2. Flange connection: 

 The flanges at both ends of the valve are fixed together with the flanges of the pipe by bolts. 

 It provides high sealing and pressure resistance. 

 Suitable for high-pressure and high-temperature environments, it is often used in large pipeline systems and occasions that require high reliability. 

 3. Welding connection: 

 The valve is directly connected to the pipe by welding. 

 It provides a permanent connection, and the sealing is very good. 

 It is suitable for occasions with high requirements for sealing and occasions that do not require frequent disassembly. 

 It is often used in high-pressure and high-temperature environments in the chemical and pharmaceutical industries. 

 4. Threaded Connection: 

 Thread the valve into the pipe. 

 It is easy to install, but it is not as common as other connection methods in health-level applications. 

 It is suitable for small-caliber pipelines and low-pressure pipeline systems. 

 It is often used in laboratories and small equipment. 

 5. Tri-Clamp Connection: 

 Also known as three-piece connection, it is a special clamp connection method. 

 It is composed of two flanges and a clamp in the middle. 

 It is easy to install and disassemble, and has good sealing. 

 It is widely used in food, beverage, pharmaceutical, cosmetics and other industries, and is suitable for occasions that require frequent disassembly and cleaning. 

 6. Sanitary Quick-Connect Fittings: 

 Connect the valve to the pipe through the quick connection joint. 

 Installation and disassembly are very convenient, and no tools are required. 

 No dead angle design, easy to clean and disinfect. 

 It is suitable for industries such as food, beverage, pharmaceutical and cosmetics, as well as occasions that require frequent disassembly and cleaning. 

 In summary, there are various connection methods of sanitary butterfly valve pipe fittings, and each method has its own unique advantages and scope of application. When choosing the connection method, it should be comprehensively considered according to factors such as specific application needs, working conditions and budget.
