Sanitary Cleanliness Standards! Analysis On The Structure Principle And Advantages Of Sanitary Butterfly Valves

Clean, sealed and stable pipeline valves are the key points for enterprises to pass industry quality inspections and meet compliance production requirements in the fields of biomedicine, food and beverage, dairy products and pure water. Common industrial valves have complex structure, many dead angles, difficult to clean, easy to cause residual media and bacterial growth, not suitable for sterile production conditions. The sanitary Sanitary butterfly valves is designed in strict accordance with national hygiene grade fluid equipment standard, with structural cleanliness, principle science and performance stability as its core, becoming the core control element of clean pipeline systems, fully adapted to high standard hygiene grade production conditions.
From the perspective of overall structural design, sanitary butterfly valves is completely different from traditional industrial valve and is tailored to the cleaner production scenarios. The overall structure adopts a minimalist straight line design, consisting mainly of valve body, stainless steel butterfly plate, food-grade rubber ring, valve stem and drive device. Compact internal cavity with no redundancy or complexity. valve body is forged from high-quality 304 and 316L stainless steel with a finely polished, smooth and delicate surface, with no sand holes, gaps, grooves or dead angles, eliminating material accumulation and residue in the physical structure. Compared with the shortcoming of sluice valve and globe valves, sanitary butterfly valves has the characteristics of unobstructed flow channels and unreserved medium, which can meet the basic requirements of sanitary production.
The working principle of sanitary butterfly valve is simple and high efficiency, which is suitable for the precise flow control requirement of clean pipe. The device relies on valve stem to drive the disc butterfly plate from 0 degrees to 90 degrees for the on/off and stepless flow regulation of pipeline medium. At full opening, the butterfly plate is parallel to the direction of the fluid, the flow path is completely unobstructed, and the resistance of the medium is close to zero, causing no loss of pressure or retention of the medium. At full opening, the butterfly plate is precisely attached to rubber ring, forming a closed barrier with zero leakage and zero dripping. At the same time, the device supports a variety of manual, pneumatic and other driving modes, and can be adapted to manual operation and fully automated intelligent pipeline systems to meet the control requirements of various clean production lines.
Strict hygiene grade material configuration is the core of its compliance with cleanliness standards. valve body is made of medical-grade stainless steel and has the characteristics of high temperature resistance, corrosion resistance and oxidation resistance. High-temperature steam sterilization, CIP on-line cleaning, acid-base sterilization. It does not rust, releases harmful substances and eliminates secondary contamination of media. The matching seal is made of food grade silicone and triethylene propylene rubber. It is nontoxic, tasteless, resistant to aging, high and low temperature, and fully complies with the food and drug safety certification standards. The whole valve has no exposed thread and splicing gaps, clean, sterilize and sterilize the blind area. It can quickly complete the cleaning operation of the entire production line and meet the production specifications of 10,000 and 100,000 cleaning workshops.
Compared with normal valves, sanitary butterfly valves have outstanding advantages in cleaning and usage. It has the advantages of stable sealing, flexible sealing structure, small opening and closing wear, not easy to leak after long use, suitable for high frequency opening and closing conditions, etc.. It has the advantages of convenient operation and maintenance, simple equipment removal and assembly, easy cleaning, low failure rate, low operating and maintenance costs, high operating and maintenance costs. At the same time, the valve body is lightweight, installation adaptability to a variety of clean pipeline layouts, which is much more adaptable than traditional valve components.
At present, the level of hygiene supervision in the food and drug industry is constantly improving, and the cleaning, purification and compliance of pipeline equipment have become the basic needs of the industry. Sanitary butterfly valve has the characteristics of reasonable structure and cleanliness, scientific working principle, stable sealing performance and extremely low operating and maintenance cost. They have become an indispensable core component of clean fluid pipeline systems, helping major industries achieve standardization, asepsis and standardized production upgrades.
