sanitary butterfly valve Description
The sanitary butterfly valve is a valve designed for high-cleanliness fluid control. It is made of 304/316L stainless steel and has a mirror-polished surface (Ra≤0.8μm). It is suitable for aseptic environments such as food and pharmaceuticals and meets 3A, GMP and other hygiene standards. Its core features include:
No dead angle design: The inner cavity of the valve body is smooth to eliminate medium residue, suitable for high-hygiene scenarios such as dairy products and medicines.
Quick disassembly and assembly: Clamp-type or quick-release connection (such as DN15~DN100), support tool-free disassembly and cleaning, and improve maintenance efficiency.
Core structure and technical parameters
Valve body and connection
Material: 304/316L stainless steel forging, resistant to weak acids, alkalis and high-temperature steam (-10℃~180℃).
Connection method:
Quick-release clamp: Suitable for DN15~DN100 pipes, installation time is shortened by 60% compared to flange type.
Welding/threaded: used for fixed installation scenarios, with better sealing (leakage grade ISO5208 A grade).
Drive and seal
Drive mode:
Manual: handle or worm gear operation, suitable for low-frequency opening and closing (such as DN≤300mm).
Pneumatic/electric: integrated actuator (such as KLB3 series), supports 4-20mA signal remote control, opening and closing time ≤2 seconds.
Sealing material:
Soft seal: EPDM, silicone or PTFE, temperature resistance ≤150℃, suitable for liquid food (such as milk, beverages).
Hard seal: three-eccentric metal seal, high temperature resistance 180℃, suitable for particle-containing media (such as powder).
Performance parameters
Pressure range: vacuum to 1.0MPa (some models can reach 1.6MPa).
Sealing test: water pressure test pressure 1.5~2.4MPa, airtight leakage rate <0.1%.

Application and advantages of sanitary butterfly valves
Food and beverages
Flow regulation of dairy pipelines (such as DN50 clamp-type butterfly valves), PTFE seals to avoid media contamination.
Biopharmaceuticals
Pipeline control for sterile preparation production, 316L material tolerates acid and alkali cleaning agents (such as CIP systems).
Daily chemical industry
Transport of cosmetic raw materials, quick-install design to meet frequent cleaning needs.
Summary of advantages:
Efficient cleaning: Mirror polishing of the inner wall reduces the risk of microbial growth.
Flexible adaptation: Multiple specifications of connection methods meet diverse pipeline layouts
