Hygienic ball valves are made of stainless steel 304SS or 316, with standard electronic polishing, smooth surface to ensure clean, no media accumulation area, no potential pollution, and can meet the special requirements of various media in the field of food and biopharmaceuticals.
The smooth, seamless, automatic emptying handicraft fluid passage of sanitary valves is also very suitable for steam and cleaning needs. The connection mode of sanitary grade valves can be selected in the form of threads, flanges, welding, clamps and jackets according to the general situation of the project.
The difference between sanitary ball valve and the common ball valve is that:
1. Hygienic grade ball valves can only be made of 304SS, 304L or 316, 316L stainless steel. After production and processing, they have been specially treated, while industrial valves can be made of cast iron, cast steel, nodular cast iron, stainless steel, with a wider range of materials. Because the use environment of health-grade valves is pharmaceutical, food, daily chemical, etc. which require high health-grade requirements, these products are edible or direct contact with the human body, so it requires that some of the machinery produced must have high sanitary conditions. But ordinary valve materials such as steel, iron, copper and other materials cannot meet, steel and iron, these materials are used as valves, its liquid or air humidity is relatively high, will corrode and rust, thus polluting products. Copper valves are the same, and copper rust is a toxic substance, so it can not be used as sanitary valves.
2. Standard electronic polishing of hygienic grade ball valves with smooth surface ensures cleanliness and no media accumulation area, which will not cause potential pollution. Industrial valves are usually designed according to the needs of users, mainly in high temperature and high pressure working environment with long service life and flexible operation mode. There are no hygienic grade valves in appearance and interior, which are smooth and beautiful, but in many places are sanitary. Grade can’t be replaced.
3. Connection mode of sanitary ball valves generally adopts clamp quick-fixing and thread connection mode; while the connection mode of industrial valves includes flange, thread, quick-fixing, welding and so on.
We can often see that sanitary ball valves are widely used in pharmaceutical, food and other industries with high health requirements. Because these industries have high requirements for hygiene, the use of valve fittings is also very demanding. Where are pneumatic ball valves used? They are generally used in pharmaceutical and food equipment systems.
