A sanitary valve is a type of valve specifically designed and used in industries where high - level hygiene and cleanliness are crucial, such as the food and beverage, dairy, pharmaceutical, and biotechnology industries. Here are its characteristics and applications:
Simple and smooth structure: Sanitary valves usually have a simple design with few dead - ends and crevices. This helps to prevent the accumulation of dirt, bacteria, and other contaminants, making them easy to clean and sterilize.
High - quality materials: They are typically made of high - quality stainless steel, such as 304 or 316L stainless steel. These materials have excellent corrosion resistance, which can withstand the cleaning agents and sterilization processes used in these industries. The wetted parts of the valve, which come into contact with the process fluids, are often made of materials that are compliant with relevant food - grade or pharmaceutical - grade standards.
Sealing performance: Sanitary valves are equipped with high - performance seals to ensure tight shut - off and prevent leakage. The seals are usually made of elastomeric materials that are resistant to chemicals and have good sealing properties at different temperatures and pressures. Common seal materials include EPDM, silicone, and fluorocarbon rubbers, which are selected based on the specific application and the nature of the fluid being handled.
Ball valves: These are widely used in sanitary applications. They offer quick - opening and - closing action and provide a tight seal when closed. Ball valves are available in different configurations, such as two - piece or three - piece designs, which allow for easy disassembly and cleaning.

Butterfly valves: Butterfly valves are known for their compact size and low - pressure drop. They are suitable for applications where a large flow capacity is required. In sanitary versions, they are designed with smooth inner surfaces and hygienic seals to meet the cleanliness requirements.

Diaphragm valves: Diaphragm valves use a flexible diaphragm to control the flow. The diaphragm separates the fluid from the valve mechanism, providing an excellent seal and preventing any contamination from the valve internals. They are often preferred in applications where a high level of purity is required, such as in pharmaceutical and biotechnology processes.
Food and beverage industry: Sanitary valves are used in various processes, including the transportation of raw materials, such as milk in the dairy industry, fruit juices, and syrups. They are also used in the processing lines for products like beer, soft drinks, and canned foods to control the flow of ingredients, additives, and the final products.
Pharmaceutical industry: In pharmaceutical manufacturing, sanitary valves are crucial for handling sterile liquids, such as drug solutions, water for injection, and cleaning agents. They help maintain the sterility and purity of the products throughout the production process, from the mixing of ingredients to the filling of vials and containers.
Biotechnology industry: In bioprocessing, where the production of biological drugs, vaccines, and other biopharmaceutical products takes place, sanitary valves are used to handle cell cultures, fermentation broths, and purified products. They play a vital role in preventing contamination and ensuring the integrity of the biological processes.
