      Comparison between 2PC Ball Valve and 3PC Ball Valve

      • DELCO Valve

      Choosing the right ball valve is very important for any plumbing or industrial project. DELCO has ball valve products suitable for various industrial applications, and understanding the differences between 2pc and 3pc ball valves can help you make the right decision. Let’s take a look at the comparison between these two ball valves.

      What is a 2-Piece Ball Valve?

      2-Piece Ball Valves are connected by two separate components, either threaded connections or bolted and flanged assemblies. These components have a valve body and end connections. They can be easily disassembled for maintenance or repair. This design offers flexibility and ease of repair, and is popular in industrial environments where frequent maintenance is required. However, because two separate parts are connected, the potential for leakage exists and it is not suitable for high pressure applications.

      What is a 3- Piece Ball Valve?

      3- Piece Ball Valves have a main body and two pipe connectors. The piping connectors are welded or threaded to the piping. Because of its three-piece construction, it can be easily assembled and disassembled without cutting the piping. making it ideal for industries such as oil and gas, chemical processing and water treatment. However, it is also more expensive than two-piece ball valves due to the complexity of its construction. The additional components and assembly complexity result in higher costs. Despite the cost factor, the benefits of easy installation and maintenance make the 3pc ball valve the preferred choice for industries requiring frequent repairs and system modifications.
