Sanitary Weld Threaded Butterfly Valve

The Sanitary Weld Threaded Butterfly Valve features a hybrid connection design combining welded and threaded ends. The welded end allows for seamless, dead-angle-free pipe connection, ensuring zero leakage and fully complying with CIP/SIP cleaning and sterilization requirements; the threaded end (R/RP/G standard) supports quick installation, disassembly, and replacement, balancing installation sealing with ease of long-term maintenance, making it an ideal choice for differentiated piping connection solutions in hygienic processes.

Materials and Hygiene Performance

1.Valve Body and Disc: Constructed from high-grade SUS304/316L stainless steel, ensuring corrosion resistance and a long service life.

2. Surface Treatment: The inner and outer surfaces of the valve body undergo precision CNC machining and electropolishing, achieving a roughness Ra≤0.8μm (maximum Ra≤0.4μm), effectively preventing residue and bacterial growth.

3. Sealing System: Equipped with FDA/3A certified food-grade EPDM, silicone, or PTFE gaskets, featuring high-temperature resistance, antibacterial properties, and zero leakage.

As a professional manufacturer in China, we strictly adhere to food and pharmaceutical industry hygiene standards, ensuring that the Sanitary Weld Threaded Butterfly Valve is fully compatible with online cleaning and sterilization processes.

Q: How to choose between the three connection types: single-weld single-thread butterfly valve, double-clamp butterfly valve, and double-weld butterfly valve?

● Single-weld single-thread butterfly valve: One end is permanently welded, and the other end is threaded for easy disassembly and maintenance.

● Double-clamp butterfly valve: Both ends adopt clamp connection for quick assembly and disassembly; the first choice for frequent cleaning and pipeline replacement.

● Double-weld butterfly valve: Fully sealed and seamless; suitable for long-term fixed pipelines requiring zero dead corners and high cleanliness.

Q: What seals are commonly used for sanitary butterfly valves? What is the temperature resistance?

A: Standard food-grade EPDM, silicone and PTFE.EPDM temperature range: -30℃ ~ +130℃, compatible with steam sterilization.PTFE features better high-temperature resistance and corrosion resistance, suitable for special acid and alkali media.All comply with FDA food contact standards.

Q: What is the service life of a sanitary butterfly valve? Is daily maintenance required?

A: Valves made of genuine 304/316L material with original factory seals can last for many years under normal clean working conditions.Regularly check the aging status of sealing rings; it is recommended to replace the seals every 1–2 years if
