Understanding Stainless Steel Ball Valves

Stainless steel ball valves are definitely one of the popular materials that many people buy. They are perfect for the food and beverage industry, agriculture as well as the pulp and paper industries. The reason behind this is because stainless steel does not corrode and when dealing with food which we consume you do not want your machines corroding. White it is true that stainless steel (SS) does not easily corrode or rust, it really depends on the oxygen level in atmosphere. For example, if it is a poor air circulation environment, depending on the grade of the SS valves the valves may or may not corrode. Therefore, it is always important when dealing in such circumstances to get a high grade type of SS valve.

The material stainless steel is not to be confused with carbon steel as carbon steel will rust at one point in its life. The difference between the two metals is the amount of chromium present. Stainless steel’s resistance to corrosion and staining, low maintenance, and familiar lustre make it an ideal material for many applications. The alloy is milled into coils, sheets, plates, bars, wire, and tubing to be used in cookwarecutleryhousehold hardwaresurgical instrumentsmajor appliancesThese are examples of a few items one may be familiar with.

It is very important to know which grade of SS you need for your application as stated above if the grade is low, it will not last or you will have problems later down the road. Therefore, always consult with the manufacturer before buying. Global Valve and Controls can provide you with 316SS, 317SS and 304SS just to name a few. There are many different grades and one may not know that 304 is not to be used in the presence of sulfuric acid.
