What is Sanitary Ball Valve?

Sanitary ball valve is made of stainless steel 304SS or 316 material, standard electronic polishing, smooth surface to ensure cleanness, no medium accumulation area, no potential pollution, and can meet the special requirements of various media in the food and biopharmaceutical fields.

The sanitary ball valve is smooth, seamless, and automatically drains the hand-crafted fluid channel. It is also very suitable for the need for steam to clean it on the spot. The connection method of the sanitary ball valve can be threaded, flange, welded, clamp, and clamp according to the project situation. And other forms. The main differences between sanitary ball valves and ordinary ball valves are:

1) The body material of sanitary ball valves are different:
Sanitary ball valves can only be made of 304SS, 304L or 316, 316L stainless steel.

After the production and processing are completed, they have been specially treated. Industrial valves can be made of cast iron, cast steel, ductile iron, stainless steel, and more widely. Because the sanitary valves are used in the pharmacy, food, daily chemicals, etc., which have high sanitary requirements.

These products are edible or directly contact with the human body. Therefore, some machinery produced must be highly hygienic. condition. However, ordinary valve materials such as steel, iron, copper and other materials cannot meet the requirements. First of all, steel and iron. These materials, as valves, will corrode and rust when the humidity is high in liquid or air, thereby contaminating the product. Copper valves are the same, and copper rust is still a toxic substance, so it can’t be used as a sanitary valve.

2) Appearance of sanitary ball valve:
Standard electronic polishing of sanitary ball valve, smooth surface to ensure cleanness, no medium accumulation area, no potential pollution;

Industrial valves are generally designed according to the needs of use, mainly for long service life and operation in high temperature and high pressure working environment The method is flexible, the appearance and interior are not smooth and beautiful without sanitary valves, but sanitary valves cannot be replaced in many places.

3) Connection method:
Sanitary ball valves generally use clamp fast assembly and threaded connection methods; while industrial valves are connected by flange, thread, quick assembly, welding, etc.
