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 are typically manufactured using investment cast and designed to withstand pressures up to 1000 psi. It’s suitable for various solid, liquid, and gas applications.

three-piece ball valve design

Ball valve 3-piece design

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. 

The ball valve’s 3-pc body allows easy maintenance and replacement of easily wearable components like stems and balls. Such 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 three-piece ball valves in your facilities is its easy assembly and disassembly. By removing only the middle portion of the valve, you can easily replace the seats and seals of your ball valve. 

You can also change your elastomers efficiently if you need to configure your valve to be applicable to various temperatures and pressures. Three-piece ball valves are highly cost-effective, especially with they fact that they can prevent line shutdowns. You can also change the seats and seals when they wear instead of getting an entire new valve.

Three-piece ball valve: When to use

If you have projects that will deal with a lot of wear and tear, particularly in high-pressure applications, three-piece ball valves would be great to use. This is because you can easily replace the parts that wear and tear easily, such as the balls, stems, and ball setas. A few common applications are 3-piece ball valves tube socket welds, 3-piece socket weld ball valve, and female national pipe taper.

Wholesale 3-piece ball valve

The average price of 3-piece ball valves on the market starts from US$ 58 and higher depending on the configurations that you need. Standing out from various 3-piece ball valve suppliers, XHVAL takes on projects with absolute flexibility in terms of pricing and negotiations.

3-piece ball valve vs. 2-piece ball valve

Similar to three-piece ball valves, two-piece ball valves also promises easy maintenance to their users. While they can also offer good sealing and functionality, there are some disadvantages to using them.

  • Cleaning a two-piece ball valve requires you to remove the pipe connector connected to the pipeline. 
  • Two-piece ball valves can be more expensive, especially in terms of replacement and maintenance. 
  • You must remove the entire valve when it becomes blocked. 
  • Three-piece ball valves can withstand pressure better than two-piece ball valves.

3-piece ball valve vs. 1-piece

One-piece ball valves tend to be cheaper than 3-piece ball valves upfront. However, the latter can be more cost-effective in the long run. As mentioned, three-piece ball valves allow you to just replace the seats and seals inside, while one-piece ball valves need you to replace the entire body. Other reasons you should prefer 3-piece ball valves over 1-piece ball valves are the following.

  • One-piece ball valves may not have correct port size configuration.
  • Three-piece ball valves are perfect for applications with heavy pressure levels.
  • You need to replace the entire one-piece ball valve.
