Sanitary ball valve is a type of valve widely used in food, pharmaceutical and other industries. Its scope of application and characteristics can be summarized as follows: 

 Scope of application 

 1. Food industry: Hygienic ball valves can be used on food and beverage production lines to control the entry and exit of raw materials and the transportation of products. Due to its high hygiene standards and good sealing, it is very suitable for handling food media and avoiding pollution. 

 2. Pharmaceutical industry: In the purified water system and sewage treatment system of the pharmaceutical industry, sanitary ball valves can quickly control the flow of the medium. At the same time, its corrosion resistance can also meet the special requirements of the pharmaceutical industry for valve materials. 

 3. Other fields: In addition, sanitary ball valves are also widely used in agricultural machinery, chemical engineering, biopharmaceuticals, brewing equipment, vacuum equipment and aerospace. 

 Distinguishing feature 

 1. High hygiene standards: The sanitary ball valve is made of stainless steel 304SS or 316 material. After high-grade polishing equipment, the surface is smooth and there is no medium accumulation area, which will not produce potential pollution. This enables it to meet the strict requirements of hygiene conditions in food, pharmaceutical and other industries. 

 2. Good sealing: The opening and closing part (sphere) of the sanitary ball valve is driven by the valve stem to rotate around the valve stem axis. When the valve stem rotates 90 degrees, the ball channel is aligned or vertical to the valve import and export channel, so as to realize the opening or closing of the valve. This structure makes the sealing surface of the sphere and the valve seat isolated from the medium when the valve is fully open or fully closed, ensuring good sealing performance. 

 3. Small fluid resistance: The sanitary ball valve has a fully permeable valve cavity design. When the fluid passes through, the resistance is small, and the resistance coefficient is equal to the pipe section of the same length. This is conducive to reducing the pressure loss of the pipeline system and improving the efficiency of fluid conveying. 

 4. Simple structure, small size and light weight: The sanitary ball valve is simple and compact in structure, small in size and light in weight, which is convenient for installation and maintenance. At the same time, its operating torque is much smaller than that of the gate valve, and the torque required for opening and closing is also very small, which makes the operation more light and flexible. 

 5. Wide range of application: The range of sanitary ball valves has a wide range of diameters, ranging from small to a few millimeters to as large as several meters. At the same time, it can also adapt to various working environments from high vacuum to high pressure. 

 6. Easy maintenance: The sealing ring of the sanitary ball valve is generally movable, and it is more convenient to disassemble and replace. This reduces the difficulty and cost of maintenance and prolongs the service life of the valve. 

 In summary, sanitary ball valves play an important role in food, pharmaceutical and other industries with their high hygiene standards, good sealing and convenient operation. During use, it should be installed and maintained in strict accordance with relevant norms and standards to ensure its normal operation and extend its service life.
