Special Design Of Sanitary Check Valve
The special design of Sanitary Check Valve is mainly reflected in the following aspects:
1. Material selection
Stainless steel material: Mainly stainless steel sus304 and sus316L are used. These two materials are widely used in the manufacture of sanitary check valves due to their excellent corrosion resistance and strength, ensuring the long-term stable operation of the valve in harsh environments.
2. Surface treatment
High-precision polishing: The inner and outer surfaces of the sanitary check valve are carefully processed by high-end polishing equipment to ensure extremely high surface precision. This not only improves the beauty of the valve, but more importantly, it ensures its sealing performance and cleanliness in a hygienic sensitive environment.
3. Sealing ring material
Multiple material selection: Usually equipped with sealing rings of various materials such as EPDM, NBR and PTFE to meet the requirements of different media, ensuring sealing performance while also meeting the needs of different industries for hygiene standards.
4. Structural design
Modular design: Modern sanitary check valves adopt modular design, which allows quick disassembly and reassembly, reduces downtime, facilitates cleaning and inspection, and meets increasingly stringent health regulations.
Self-draining design: The valve structure with self-draining design ensures that the medium is completely discharged during the cleaning process without residue, reducing the risk of contamination.
Intelligent technology integration: Some high-end sanitary check valves are equipped with sensors to monitor the operating status in real time, predict maintenance needs, and even automatically take measures in abnormal situations to ensure process safety. Remote monitoring and diagnostic functions also make maintenance more convenient and efficient.
5. Two-way protection function
Dual seal design: In some critical liquid delivery systems, such as the transmission of sterile media, sanitary two-way check valves can avoid backflow and provide sealing protection in both directions to ensure the safety of the system when switching between forward and reverse flows and avoid any possible contamination risks.
In summary, the special design of the sanitary check valve covers many aspects such as material selection, surface treatment, sealing ring material, structural design and two-way protection function to ensure that it meets the high standards of hygienic sensitive industries such as food and pharmaceuticals.
