Core characteristics and industry application description of sanitary grade stainless steel welded butterfly valve:
1、 Core Features
1. High grade materials and surface treatment
Food grade stainless steel: The valve body and internal components are made of 304/316L stainless steel, which has strong corrosion resistance (especially acid, alkali, salt solution resistance) and meets international certification standards such as FDA and EHEDG.
Mirror polishing process: Surface roughness ≤ 0.8 μ m (Ra value), eliminating dead corners, effectively preventing medium residue and bacterial growth.
2. Sealing structure and reliability
Triple eccentric design: Achieve bidirectional zero leakage of metal hard seals or elastic seals, with a pressure resistance of up to 1.6MPa and a suitable temperature range of -10 ℃~150 ℃.
Advantages of welding connection: The valve body and pipeline are connected by argon arc welding, eliminating the risk of leakage at flange/threaded interfaces. The weld has passed a pressure holding test at 1.5 times the working pressure.
3. Maintain convenience
Modular structure: supports online quick disassembly, seal ring replacement only takes 2 hours, significantly reducing downtime.
There are basically no dead corners in the flow channel: the smooth inner cavity design is adapted to the CIP/SIP (in-situ cleaning/sterilization) process, meeting the high-frequency hygiene and cleaning needs.
2、 Industry Applications
1. Food and beverage industry
• Dairy production: used for controlling the feeding and discharging of fermentation tanks, CIP cleaning of pipelines, and avoiding contamination of media such as milk and yogurt.
Brewing and beverage filling: Ensure no residue in beer and juice conveying pipelines, in compliance with HACCP hygiene standards.
2. Pharmaceutical and Bioengineering
Aseptic process control: applied to pharmaceutical reactor feeding, purified water systems, and biological fermentation tanks, resistant to high-temperature steam sterilization (SIP).
Vaccine/drug delivery: The 316L valve body is suitable for strong acid/alkali media (such as chlorine containing solutions), and PTFE sealing components can be selected to be compatible with corrosive drugs.
3. Emerging industries
New energy battery manufacturing: Transporting lithium battery electrolyte (such as lithium hexafluorophosphate solution), with resistance to hydrofluoric acid corrosion to ensure safe transportation.
Fine Chemicals: Control high-purity fluids in the production of cosmetics and biologics to avoid metal ion contamination.
