What is the difference between sanitary and industrial valves

Date:2019-08-21

Sanitary grade valves are used to compare hygiene grade requirements what is the difference between sanitary grade valves and industrial valves.

Sanitary grade valve is used in the situation of higher hygiene grade requirements, from the appearance and function, it can be said that there is no difference with the ordinary valve. That is to say, the difference between sanitary valves and ordinary valves lies in the different materials they make and the situations in which they are used. Here is the difference between sanitary valves and ordinary industrial valves.

First of all, the materials are different, because the environment for the use of sanitary valves is very demanding for pharmaceuticals, food, daily chemicals, and so on. These products are edible or in direct contact with the human body.Therefore, some of the machinery required to be produced must have very high sanitary conditions. And ordinary valve materials such as steel, iron, copper and other materials can not be satisfied, first of all, steel and iron, these materials as valves, if the humidity in the liquid or air is relatively high, it will corrode and rust, thus polluting the product. Copper valves are the same, and copper rust is also a toxic substance, so it can not be used as a sanitary valve.
Sanitary valves are made of stainless steel, stainless steel has a very good corrosion resistance, but also non-toxic and tasteless, will not cause pollution to the products. Sanitary valves are generally 304SS or 316 stainless steel, after the completion of production and processing, after special treatment, in many ways can not be compared with industrial valves, such as cleanliness, simple installation, and so on, which is specially for food. Valves made in pharmaceutical and other industries.Industrial valves are generally made according to the needs of use, mainly in the working environment of high temperature and high pressure, the service life is long and the mode of operation is flexible, and the appearance and interior of the valve are not smooth and beautiful. But in many places there is no substitute for hygiene.

Introduction to the concept and working principle of Ball Valve

Ball valve, defined in standard GB/T21465-2008 "valve terminology" as a valve driven by the stem and rotated around the axis of the stem. It is mainly used to cut off or connect the medium in the pipeline, and can also be used for the adjustment and control of fluid.

Types and advantages of ball valves

Ball valve and plug valve are the same type of valve, only its closure is a sphere, the sphere rotates around the centerline of the valve body to open and close. The ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. Ball valve is a new type of valve which has been widely used in recent years.

Working principle and matters needing attention of stainless Steel Ball Valve

Stainless steel ball valve working principle is to rotate the spool to make the valve open or blocked, the ball valve body can be integral, can also be combined.?The following is to introduce you to the stainless steel ball valve related knowledge.?

Installation method and matters needing attention of Ball Valve

Preparation before installation. (1) the front and rear lines of the ball valve are ready. The front and rear pipes should be coaxial and the two flange cover should be parallel. The pipe should be able to bear the weight of the ball valve, otherwise the pipe must be properly supported.
