Any quick internet search for valves will show many different results: manual or automated, brass or stainless steel, flanged or NPT, one piece, two piece, or three piece, and more. With so many different types of valves available, how can you be sure you are purchasing the right type? While your application will help guide your proper valve selection, it is important to have some basic understanding of the different types of valves offered.
One-piece ball valves have a solid, cast body which reduces the risk for leakage. They are inexpensive and generally not repaired.
Two-piece ball valves are some of the most common ball valves used. As the name suggests, the two piece ball valve consists of two pieces, one piece that has one end connection and the body. The second piece fits into the first, holds the trim in place and includes the second end connection. Once installed these valves typically cannot be repaired unless they are removed from service.
Again, as the name suggests, three-piece ball valves consist of three pieces: two end caps and a body. The end caps are typically threaded or welded to the pipe and the main body section may be easily removed for cleaning or repair without removing the end caps. This can be a very valuable option because it prevents a line shutdown if maintenance is required.
By comparing the features of each valve with your application requirements, you will be able to make an informed decision on which will best suit your needs. Please visit our valves website to learn about our ball valve product line or start configuring today.
The 2 piece stainless steel ball valve is probably the most widely used ball valve. The 2 piece ball valve will open or shut off flow on most liquids and gases quickly and easily and is suitable for just about any application where a simple on/off action is needed. Flow rate can also be controlled by partially opening or closing the valve to various degrees. Also referred to as a two-way ball valve, since it allows flow in any direction straight through from inlet to outlet. Being threaded ball valves they are quick to install and easy to use, requiring no tooling for installation. The two piece ball valve is the best priced full port ball valve (full bore), allowing the inside diameter of the pipe to remain constant and unrestricted. This means that the 2 piece SS ball valve has no pressure drop and keeps the flow rate high.
