Detailed Introduction Of Sanitary Valves
Sanitary valves are a type of valve designed for the food, beverage, pharmaceutical, cosmetics and other industries. Their main feature is that they can meet the requirements of high hygiene standards. The following is a detailed introduction to sanitary valves:
Sanitary valves have a wide range of applications:
Food industry: fluid control in the production process of dairy products, juice, beer, wine, etc.
Pharmaceutical industry: fluid processing in the fields of drug production, water for injection, bioengineering, etc.
Cosmetics industry: processing and filling of cosmetic raw materials and finished products.
Bioengineering: fluid control in processes such as cell culture and fermentation.
Material of Sanitary Valve:
304 stainless steel: This is a common stainless steel material with good corrosion resistance and processing performance, suitable for most general sanitary applications.
316L stainless steel: Compared with 304 stainless steel, 316L contains more nickel and molybdenum, so it has good corrosion resistance, especially stronger corrosion resistance to chloride environments, and is often used in more demanding sanitary environments and marine environments.
Other metal materials:
Nickel alloys: such as Hastelloy, which exhibit excellent corrosion resistance in some chemical environments.
Titanium: Titanium materials have high corrosion resistance and are suitable for some special sanitary applications.
Non-metallic materials:
Polytetrafluoroethylene (PTFE): As a sealing material, PTFE has excellent chemical stability and high temperature resistance, and is often used in valve seals.
Ethylene propylene rubber (EPDM): EPDM is a commonly used sealing material with good heat resistance, oxidation resistance and ozone resistance.
Silicone rubber: Silicone rubber is also a commonly used sealing material that can maintain good elasticity and sealing performance over a wide temperature range.
Characteristics of sanitary valves:
Material selection:
Sanitary valves are usually made of easy-to-clean and corrosion-resistant materials such as stainless steel (such as 304, 316) to prevent microbial growth and chemical contamination.
Surface treatment:
The surface is polished, mirrored or electropolished to reduce places for bacteria to hide and ensure a smooth surface without dead corners.
No dead corner design:
The internal structure of the valve is designed without dead corners, which is easy to clean and disinfect to avoid contaminant residues.
Lead-free and no harmful substances:
Avoid using materials containing lead or other harmful substances to comply with food safety regulations and standards.
Standardized size:
Comply with international or national standards such as DIN, ISO, etc., to facilitate compatibility with other sanitary piping systems.
Sealing performance:
Use sanitary gaskets, O-rings and other sealing materials to ensure good sealing performance and prevent leakage.
Certification:
Pass relevant health and safety certifications such as FDA, EHEDG, 3A hygiene standards, etc. to prove its suitability for industries with strict hygiene requirements.
Easy to maintain:
Designed for easy disassembly and cleaning, easy for regular maintenance and replacement of parts.
Scope of application:
Applicable to food processing, beverage production lines, pharmaceutical production, cosmetics manufacturing and other industries.
Operation mode:
Can be manual operation or automated control, such as electric or pneumatic actuator drive.
When selecting sanitary valves, consider the requirements of the actual application scenario, such as the nature and temperature of the working medium, and whether specific hygiene standards and certification requirements need to be met.
