The main differences between sanitary and non-sanitary valves lie in their design, materials, and applications:
Materials
Sanitary Valves: Made from materials that are corrosion-resistant and easy to clean, such as stainless steel (often 304 or 316L). They must meet strict hygiene standards.
Non-Sanitary Valves: May be made from a wider range of materials, including cast iron, plastic, or carbon steel, which might not be suitable for sanitary applications.
Design
Sanitary Valves: Feature smooth surfaces, minimal crevices, and are designed for easy disassembly and cleaning (often using methods like CIP-clean-in-place). They often have a polished finish to prevent bacterial growth.
Non-Sanitary Valves: May have rough surfaces and designs that are not focused on cleanliness, making them harder to sanitize.
Applications
Sanitary Valves: Used in industries like food and beverage, pharmaceuticals, and biotechnology, where hygiene is critical.
Non-Sanitary Valves: Used in general plumbing, industrial applications, and systems where hygiene is less of a concern.
Overall, sanitary valves are specifically engineered for environments where cleanliness and safety are paramount, while non-sanitary valves are more versatile for various industrial applications.
