Basic Introduction of Stainless Steel Valve

An alleged metal valve is a valve, mainly made of metal, which regulates the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing a variety of passageways.

The types of metal used within the body of a valve comprise 301, 304, 316, 304L and 316L. According to international standards, in addition, they can be classified into CF8, CF3, CF8M along with CF3M.

There are all types of  Stainless Fitting (which is also known as ”  ข้อต่อสแตนเลส  ” in the Thai language  )  metal valves, such as gate valve, ball valve, butterfly valve, check valve, plug valve, needle valve, septic valve, steam trap, air-operated valve and so forth.

  • So far as we understand, stainless steel is a common name for alloy metals that consist of 10.5% or maybe more Chromium (Cr) and significantly more than 50% Iron (Fe). The chromium content in stainless steel alloys is that which generally prevents rust.

  • It helps to beg the iron to corrode by water and oxygen. It operates by reacting with oxygen to produce a tough, adherent, invisible and passive layer of chromium oxide film on the steel surface. Anyway, the additions, such as nickel have been utilized to boost the overall corrosion resistance required in greater competitive usage or even conditions.





Owing to the components, it’s famed because of its resistance to corrosion and discoloration, low maintenance, relatively minimal priced, and recognizable sheen also it is a perfect base material for a host of commercial applications, particularly for valve application. On basis of properties of this stainless steel, metal ball valve gets got the top features of corrosion
