What is a 3 Piece Ball Valve?
A three-piece ball valve is made of three easy-to-remove components that are connected with bolts, which makes it friendly for cleaning.
A great benefit of a 3-pc ball valve is that you only have to remove the piece at the center when cleaning the line. Three-piece ball valves from Eastern United are typically manufactured using investment cast and designed to withstand pressures up to 1000 psi. They’re suitable for various solid, liquid, and gas applications.

Eastern United Three-Piece Ball Valve Design
The 3-piece ball valve parts consist of two pipe connectors and one primary component. The pipe connectors are installed via welding or threading to the pipeline. The main body then attaches to the middle portion of these two pipe connectors.
Eastern United’s 3-pc body design allows easy maintenance and replacement of easily wearable components like stems and balls. This straightforward and low-cost care makes it highly recommended for high-wear applications.

What Are the Advantages of a 3-Piece Ball Valve?
The main benefit of using Eastern United three-piece ball valves in your facilities is the easy assembly and disassembly. By removing only the middle portion of the valve, you can easily replace the seats and seals.
You can also change elastomers efficiently if you need to configure the valve for different temperatures and pressures. Eastern United’s three-piece ball valves are highly cost-effective, especially considering they can prevent line shutdowns. Instead of replacing the entire valve, you can simply change the seats and seals when worn.
When to Use Eastern United Three-Piece Ball Valves
If your project deals with heavy wear and tear or high-pressure conditions, Eastern United three-piece ball valves are an ideal choice. Their design makes it easy to replace wear-prone parts such as the ball, stem, and seats.
Common applications include:
- 3-piece ball valve tube socket welds
- 3-piece socket weld ball valves
- Female national pipe taper setups

3-Piece Ball Valve vs. 2-Piece Ball Valve
Two-piece ball valves offer good functionality and are easy to maintain, but they do have limitations:
- Cleaning requires removing the pipe connector.
- Maintenance and replacement can be costlier.
- Entire valve needs removal when blocked.
- Lower pressure tolerance compared to 3-piece valves.
Eastern United recommends 3-piece ball valves for better pressure handling and easier servicing.
3-Piece Ball Valve vs. 1-Piece Ball Valve
While one-piece ball valves have a lower initial cost, they require full replacement when damaged. In contrast, Eastern United’s 3-piece ball valves allow internal component replacements—seats, seals, stems, and balls—making them more cost-effective long term.
Additional reasons to choose Eastern United’s 3-piece ball valves:
- Proper port size configuration
- Superior pressure resistance
- Partial component replacement reduces downtime and costs
