What is the difference between sanitary valves and ordinary valves

Sanitary valves are used in situations that require relatively high levels of hygiene. In fact, they are not much different from ordinary valves. Speaking of which, sanitary valves are the same as ordinary valves, but they are used in different situations. Let's introduce the differences between them and ordinary industrial valves.

First of all, the materials are different, because sanitary valves are used in pharmaceuticals, food, daily chemicals, etc. that have high hygiene requirements. These products are edible or in direct contact with the human body, so some of the machinery required to produce them must have Very high hygiene conditions. However, ordinary valve materials such as steel, iron, copper and other materials cannot meet the requirements. First of all, let's talk about steel and iron. As valves, these materials will corrode and rust if the humidity in liquid or air is relatively high, thus contaminating the product. The same is true for copper valves, and copper rust is still a toxic substance, so it cannot be used as a sanitary valve.

Sanitary valves are made of stainless steel. Stainless steel has good corrosion resistance, is non-toxic and tasteless and will not pollute the product. Sanitary valves are generally made of 304SS or 316 stainless steel. They have undergone special treatment after production and processing. They are incomparable to industrial valves in many aspects, such as cleanliness, simple installation, etc. They are specially designed for food, medicine and so on. Valves manufactured by other industries. Industrial valves are generally modeled according to the needs of use, mainly for long service life and flexible operation in high-temperature and high-pressure working environments. The appearance and interior are not as smooth and beautiful as sanitary-grade valves, but in many places they cannot be replaced by sanitary-grade valves.
