A so-called stainless STEEL VALVES is a valve, mainly made of stainless steel, which regulates the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing many passageways. The types of stainless steel used in the body of a valve are 301, 304, 316, 304L and 316L. According to worldwide standards, they also can be classified into CF8, CF3, CF8M and CF3M. There are all kinds for the stainless steel valves, this kind of as gate valve, ball valve, butterfly valve, examine valve, PLUG VALVE, needle valve, baiting valve, steam trap, air-operated valve and so on.

As far as we know, stainless steel is a common name for steel alloys that consist of 10.5% or more Chromium (Cr) and a lot more than 50% Iron (Fe). The chromium content in stainless steel alloys is what normally prevents corrosion. It helps to procrastinate the iron to rust by oxygen and water. It operates by reacting with oxygen to type a tough, adherent, invisible, passive layer of chromium oxide film for the steel surface. Besides, the additions, this kind of as nickel are used to raise the general corrosion resistance needed in more aggressive utilization or conditions.

Because of those components, it is well-known for its resistance to corrosion and staining, low maintenance, relatively low cost, and familiar luster and it can be an ideal base material for a host of industrial applications, especially for valve application. On basis of properties for the stainless steel, stainless steel ball valve has the attributes of corrosion-proof, rust-proof, water-proof and durability.

Therefore, it is widely used in loads of industries where the resistance to corrosion is required, this kind of as chemical, petrochemical, oil, paper-making, mine, electricity, gas, food, pharmaceutical, water supply, mechanical equipment, electronic, urban construction and so on.

Nowadays, stainless steel valves have been the necessary products in all sorts of fields. However, there are only a few of valve manufacturers who attain the worldwide standard. So when persons buy this valve, they must require the vendor to show the certifications for production. Through this way persons can avoid buying the unqualified products. What
