Differences between Ball Valves and Plug Valves

The flow of liquids and gases can be controlled using valves in a variety of settings. Valves come in a variety of types, functions, porting, durability, and control capabilities. On the other hand, plug valves and ball valves serve the same purpose. They both regulate the flow of gas or liquid using either a straightforward on/off function or a multipath function. So, what are the differences between those valves?

In this post, I want to share the differences between ball valves and plug valves in terms of body structure, function, application, and maintenance. And on the last post, we will learn how to choose the right one. Before we jump into the difference between those valves, let’s learn some basics about ball valves and plug valves.

What Are Ball Valves?

Ball valves are valves with an internal spherical disc. There is a port, or hole, in this disc. When the port and both ends of the valve are lined up, the valve is in the open position, enabling the medium to freely flow through it. When the port is perpendicular to the ends of the valve, the valve closes, and the medium flow stops. Read More
