Sanitary valves are special valves. The difference between them and ordinary valves is that they are used in different environments. Sanitary valves are mostly made of high-grade stainless steel, so they have a higher sanitation level. Of course, not all stainless steel valves can be called sanitary valves. Sanitary valves need to be certified.

Sanitary Valve has different certification standards in different regions. Common standards include ASME-BPE (Bio-Processing Equipment) in the United States and EHEDG (European Hygienic Equipment & Design Group) in Europe.

Process related: In addition to the above two responsible for equipment design, the US FDA and USP mainly focus on the use of materials, the entire equipment process, and how to certify and implement. FDA is divided into two parts: GMP and PAT. The main standards involved are 3A and FDA. 3A focuses on equipment design while FDA focuses on materials, processes and certification.
