Sanitary ball valve is a valve type 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: Sanitary ball valves can be used on food and beverage production lines to control the entry and exit of raw materials and the delivery 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 standard: The sanitary ball valve is made of stainless steel 304SS or 316. After being treated with high-grade polishing equipment, the surface is smooth and has no media accumulation area, which will not cause potential pollution. This enables it to meet the strict requirements of food, pharmaceutical and other industries for sanitary conditions. 

 2. Good sealing: The opening and closing part (ball) of the sanitary ball valve is rotated around the axis of the stem driven by the valve stem. When the stem rotates 90 degrees, the ball channel is aligned or perpendicular to the valve inlet and outlet channel, so as to realize the opening or closing of the valve. This structure allows the sealing surface of the sphere and the valve seat to be isolated from the medium when the valve is fully opened or fully closed, ensuring good sealing performance. 

 3. Small fluid resistance: The sanitary ball valve has a fully penetrating valve cavity design. The resistance of the fluid passes through is small, and the resistance coefficient is equal to that of 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 transmission. 

 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, and easy to install and maintain. 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, making the operation more light and flexible. 

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

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

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