When choosing Sanitary Butterfly Valve, the following key factors should be considered:

‌Material selection‌:
Key components such as valve body, valve plate and seals should be made of sanitary materials, such as 304 or 316L stainless steel, which are highly corrosion-resistant and suitable for a variety of environments.

‌Sealing performance‌:
Sealing performance is an important indicator of sanitary butterfly valves. Valves with good sealing structure should be selected to ensure long-term and reliable sealing effect and prevent medium leakage.

‌Functionality‌:
It is preferred to use sanitary butterfly valves with quick-install design. This design is convenient for disassembly and cleaning, ensuring that every corner is clean and sterile, meeting hygiene requirements.

‌Brand and reputation‌:
Choose products from well-known brands, which usually have more advanced manufacturing processes, stricter quality control and more reliable performance, and can meet high standards of hygiene requirements.

‌Technical specifications and performance‌:
According to the technical specifications such as system flow requirements, pressure loss, operating speed and control options, select the appropriate valve size and actuator type.

‌Working environment and medium characteristics‌:
Consider the type of medium, corrosiveness, viscosity, temperature and pressure that the valve will work in, and select suitable valve body, butterfly plate and sealing materials to ensure the corrosion resistance and service life of the valve‌.

‌Installation and maintenance‌:
Consider the installation space, connection method and maintenance convenience of the valve to ensure that the valve can be easily installed in the designated position and effectively connected with other equipment, while facilitating daily maintenance and cleaning‌.

In summary, when choosing a sanitary butterfly valve, factors such as materials, sealing performance, functionality, brand reputation, technical specifications, working environment, installation and maintenance should be comprehensively considered to ensure that high-quality products that meet the needs are purchased.
