Sanitary Check Valve The special requirements of the pharmaceutical industry mainly include materials, surface treatment, design features, sealing, and compliance with relevant hygiene standards.

Material:

The pharmaceutical industry has strict requirements on the materials of sanitary check valves, and usually uses high-quality stainless steel materials such as SUS304, 316/316L, etc. These materials have excellent corrosion resistance and hygiene, and can resist the erosion of various chemical cleaners and disinfectants to ensure the safety and reliability of the product.

Surface treatment:

The surface of the sanitary check valve needs to be finely mechanically polished or electrolytically polished to achieve an extremely low surface roughness (Ra value), thereby reducing the possibility of bacterial adhesion and facilitating cleaning and disinfection. This helps maintain a sterile environment and meets the high requirements of the pharmaceutical industry for hygiene standards.

Design features:

In terms of design, sanitary check valves need to ensure that there are no dead corners and no liquid accumulation areas to facilitate thorough cleaning, prevent microbial growth and cross-contamination of products. For example, the automatic emptying design can ensure that there is minimal residual liquid in the pipeline, further reducing the risk of contamination.

Sealing:

The pharmaceutical industry has extremely high requirements for the sealing performance of sanitary check valves, and must ensure no leakage to prevent media leakage and external contaminants from entering. High-precision processing technology and high-quality sealing materials are the key to ensuring the long-term and stable operation of the valve.

Compliance with relevant health standards:

Sanitary check valves must strictly comply with FDA, 3A and other sanitary engineering standards to ensure the purity of the fluid. At the same time, valves need to undergo rigorous testing and certification to meet the pharmaceutical industry's stringent standards for equipment and environment.

In summary, the special requirements for sanitary check valves in the pharmaceutical industry cover multiple aspects such as materials, surface treatment, design features, sealing, and compliance with relevant health standards. These requirements ensure the safety and reliability of valves in the pharmaceutical process, and safeguard the quality and safety of drug production.
