Welding manual butterfly valve

1. Definition and Application
Sanitary valves are devices used to control the flow of liquids or gases in pipelines. Their core function is to ensure the safety, hygiene, and non-contamination of the media. They are widely used in industries such as food processing, pharmaceuticals, healthcare, and dairy, mainly for regulating flow, preventing backflow, and protecting systems from overpressure effects.
2. Main Features
Material: Sanitary valves are typically made of high-grade stainless steel (such as 304 or 316L), which have good corrosion resistance, cleanability, and non-toxicity.
Design: The design of sanitary valves focuses on smooth surfaces, no gaps, and no dead ends to prevent bacterial growth and media residue.
Cleaning and Sterilization: Sanitary valves support Cleaning-In-Place (CIP) and Sterilization-In-Place (SIP), meeting strict hygiene requirements.
Sealing: High-purity elastomer or plastic seals are used to ensure no leakage during valve operation.
Compliance: Sanitary valves must comply with strict industry standards, such as FDA, 3A, EHEDG, etc.
