Everything About Sanitary Valves

If you want to read one article to know everything about sanitary valve, then read this one. This article includes the most interesting and helpful posts about sanitary valves in our website. Here you can find short and concise posts, which give you the knowledge about valves without costing you too much time! Here you can see things clearly and lively with videos and gifs!

What are the sanitary valves?

To be short, sanitary valve is a special type of valves. The difference is that sanitary valve has a higher manufacturing standard that he part of the valve in contact with the medium is usually made of 304SS or 316 stainless steel, which is non-toxic and is not easy to cause corrosion. Therefore, sanitary valves are commonly used in dairy, food, pharmaceutical, medical, and chemical applications. Their common features include easy cleaning, crevice free, and polished contact surfaces.

Different types of sanitary valves

Similarly with ordinary valves, sanitary valves can be categorized into sanitary butterfly valve, sanitary ball valve, sanitary check valve and other types of valve. For specific information about the types of valve, please refer to Basic types of sanitary valves. And below is a short video introducing some of the basic types of valves.

Sanitary Valve Materials

304 and 316 stainless steel are the two most popular materials used in sanitary valves. Both of these two stainless steel are non-magnetic, austenitic, and non-hardenable through heat treatment. They are quite durable, and are easily formed and fabricated. 316 steel has better corrosion resistance due to the addition of Molybdenum, but its price is also higher. 316 steel can be worth the expense if you need to have superior corrosion resistance. But for many other applications, grade 304 will serve perfectly fine.

Valve Test

In general, we will check whether the valve is qualified from three aspects: switch, leakage and strength.
The switch of the valve is usually examined by means of a sealed pressure test. If the valve switch is feasible and there is no leakage, it is considered to meet the standard.
Leakage includes internal leakage and external leakage, both of which should be carefully tested by the valve manufacturer.
Strength of the valve determines the service life of your valve. Thus, the valve body, disc and sealing surface of a qualified valve must meet the corresponding requirements to prevent corrosion of the valve.

Valve Disassembly

During the use of the valve, even as for the sanitary valve, it is unavoidable that some deposits or contaminants may appear inside it. In order to extend the life and performance of the valve, the valve should be disassembled and cleaned regularly. Valve disassembly does not require much professional knowledge, so we can do it by ourselves. Here is a video of ball valve disassembly for you.

Valve Maintenance

In order to extend the service life of the valve, we need to do a good job in the storage of the valve. Its purpose of is to prevent the valves from being damaged or of reduced quality during storage. In fact, improper storage is one of the important reasons for valve damage.
