The Main Differences Between Sanitary Grade Ball Valves And Food Grade Ball Valves

The main differences between Sanitary Ball Valve and food grade ball valves are their design, materials, applications, and related hygiene and food safety standards.

Design: Both sanitary grade ball valves and food grade ball valves are designed as rotary valves, which can be opened and closed by rotating the ball 90 degrees around the axis of the valve stem. However, sanitary grade ball valves are designed to be easy to clean and disinfect, with smooth internal surfaces and no dead corners, thus avoiding the growth of microorganisms and cross contamination of products.
Material: Sanitary grade ball valves are usually made of high-quality stainless steel materials such as 304 and 316L, which have good corrosion resistance and can resist the erosion of various chemical media. Although food grade ball valves also use stainless steel, their material selection may be more extensive and not necessarily limited to the above two types.
Application: Sanitary grade ball valves are mainly used in environments that require high hygiene standards, such as food, beverage, dairy, pharmaceutical and other industries. Food grade ball valves are mainly used in the food processing industry, such as food and beverage production lines, emphasizing the hygiene and safety of the contact parts between valves and food.
Hygiene and food safety standards: The design and production of sanitary grade ball valves comply with strict hygiene and food safety standards, such as GMP requirements, to ensure the hygiene and quality of the products. Although food grade ball valves also require compliance with food safety standards, their strictness may not be as high as sanitary grade ball valves.
