Sanitary Butterfly Valve is a quality valve designed specifically for the food, beverage, dairy, brewing, pharmaceutical, bioengineering, fine chemical and other industries. It is characterized by excellent hygienic performance to ensure that the medium will not be contaminated during transmission. So do you know what are the characteristics and structure of sanitary butterfly valves?

The characteristics and structure of sanitary butterfly valves are as follows:
Sanitary design:
Full-bore design: The butterfly plate is consistent with the pipe diameter to reduce fluid resistance and turbulence, and facilitate self-cleaning.
Smooth surface: The inner and outer surfaces are polished, Ra≤0.8μm, to prevent microbial adhesion.
No dead angle design: There are no grooves and dead areas in the valve body to ensure smooth flow of the medium and easy CIP/SIP cleaning.
Material selection:
Valve body and butterfly plate material: commonly used stainless steel 316/316L, with excellent resistance and biocompatibility.
Sealing materials: EPDM (ethylene propylene diene rubber), PTFE (polytetrafluoroethylene), silicone, etc., meet food contact standards, and have good temperature resistance and chemical resistance.
Connection method:
Sanitary clamp connection: Use quick-release clamps to facilitate disassembly and assembly, simplifying the cleaning process.
Welding connection: Suitable for high temperature and high pressure environments to ensure the tightness and stability of the connection.

The design of sanitary butterfly valves strictly complies with hygiene standards, such as the US FDA (Food and Drug Administration), 3A Sanitary Standards (US 3A Sanitary Standards) and EHEDG specifications to ensure the product's performance in terms of cleanliness, easy cleaning, and corrosion resistance.
