Sanitary check valves are key components used in food, pharmaceutical, beverage and other industries, and their material selection and compliance with standard requirements are crucial. These requirements ensure the hygienic and safety performance of the valve, as well as its reliability in fluid control processes.
The material selection of sanitary check valves is a key factor in ensuring the sanitary performance of the valve. The following are some common sanitary valve materials:
Stainless steel:
Stainless steel, such as 316L stainless steel, is a common choice for sanitary check valves. It has excellent corrosion resistance and can operate stably for a long time in acid and alkali environments without causing contamination to the fluid.
PTFE:
PTFE is a material with excellent chemical resistance and high temperature resistance, and is suitable for handling acid and alkali solutions and high temperature fluids.
Silicone Rubber:
Silicone rubber has good high temperature resistance and chemical corrosion resistance, and is suitable for high temperature and high pressure applications.
EPDM: EPDM rubber is widely used in food, beverage and other applications and has excellent temperature resistance and corrosion resistance.
Sanitary check valves must meet a series of strict hygiene standards to ensure their suitability for use in food, pharmaceutical and other fields.
3A standard:
3A health standards are representatives of North American health standards and are widely used in the food and pharmaceutical industries. These standards specify the material, design, manufacturing and installation requirements for sanitary valves to ensure hygiene.
EHEDG Standard: EHEDG (European Hygienic Engineering and Design Group) is an international organization focused on sanitary engineering and design. Its standards ensure that equipment and engineering design meet sanitary requirements and are suitable for sanitary check valves.
BPE standard: BPE (bioprocess equipment) standard is mainly applicable to the pharmaceutical industry, especially in the field of biotechnology. These standards stipulate the design, material selection, manufacturing process and other requirements of sanitary valves.
FDA Certification: The U.S. Food and Drug Administration (FDA) certification requirements ensure that sanitary check valves will not cause adverse reactions when in contact with food and drugs.
The material selection and standard requirements of sanitary check valves are key factors to ensure that the valve performs well in terms of hygiene and safety. Therefore, when selecting sanitary check valves, both manufacturers and users should carefully consider material properties and compliance with standards to ensure the performance and reliability of the valve while ensuring the hygienic safety of the production process.
