The Ultimate Guide to 1 Piece, 2 Piece, and 3 Piece Ball Valves

What is the difference between a 1Pc, 2Pc and 3Pc Ball Valve?

Ball valves come in one, two, or three pieces. One piece being manufactured with only 1 body part, Two piece ball valves consist of two separate pieces, with the connection between them being either threaded or a bolt and flange assembly. As you may have guessed, a 3 piece ball valve consists of three pieces, two end caps and a body

Ball valves are employed throughout many commercial, institutional, and industrial venues where the need to isolate part of a system is necessary, or even just to regulate the on/off condition of system fluid flow. The product variants are almost uncountable, with a version to accommodate almost any application. When selecting a ball valve, one facet of construction will be evident in your research.


1 Piece Ball Valve

 A one piece ball valve, can also be referred to as single piece ball valve, has a body and end connections formed from a single piece of material. This construction presents a comparatively reduced number of opportunities for leakage. The valve trim and seals are inserted through one of the end connections. This type of valve will not have a port size equal to the line size. The simplicity of the one piece body design tends to make their cost lower than the other versions. Once the valve is in place, it cannot be serviced without removing the entire valve assembly from the piping system. One piece ball valves are inexpensive and generally not repaired.

2 Piece Ball Valve

A two piece ball valve consist of two separate pieces, with the connection between them being either threaded or a bolt and flange assembly.  They generally have one piece that includes an end connection and the body, plus a second piece that fits into the first that will hold the trim in place and provide the second end connection. The construction presents an additional leak potential where the two pieces are joined, but also allows disassembly of the valve for replacement of the internals. These valves can provide full port service and bidirectional flow shutoff.  We sell these as female threaded and flanged ends.

3 piece body ball valve

A three piece ball valve ball valve consists of three pieces, two end caps and a body. The end caps are welded, threaded, or flanged to connect to the pipe on either side.  A three piece ball valve essentially separates the connection portions of the valve assembly from the body of the valve. These will be more expensive than either of the other two types, but their allowance for removing the valve body and trim from the piping system while leaving the connections in place may prove valuable for many applications. Full port and bidirectional shutoff can be provided by this construction.

2 piece ball valve vs 3 piece

The main advantage for a 2 piece vs 3 piece ball valve is that the 2 piece ball valves are cheaper.  The main advantage for a 3 piece ball valve vs 2 piece is that you can easily change the seals by unbolting the end caps and removing the  centre section.
