What Are the Common Types of Ball Valves

May. 09, 2022

Ball valves are valves specifically designed to be used in pipeline applications to shut off and open the flow of substances. For example, they are commonly used in gas handling, piping and industrial piping systems to control the flow of gases or liquids through pipes. Ball valves consist of several components, including a float, stem, seat, and handle.

Ball Valve Design

The system works as follows: The valve has a rotatable ball with an opening in the middle that connects to the stem and handle. The handle is turned a quarter turn and the ball opening is aligned with the pipe flow, allowing the liquid or gas to flow freely through the valve. When the ball opening is in the closed position, the flow of material is blocked.

Ball valves are most commonly used because they shut down systems quickly and efficiently. In addition, they are durable, provide a secure seal for long-term use, and are easy to service and operate. As a result, these types of valves are often preferred over other angle-stroke globe valves.

Common types of ball valves

In general, there are five types of ball valves that offer similar functions and operate identically. However, the biggest difference is in the body construction and how the ball is contained within the housing of the assembly. Body styles include split, top-mount, single, three-piece, and welded.

In addition, ball valves depend on the type of opening inside the ball. Different types of holes will improve accuracy when closing the valve, they can contain multiple open or closed settings, and they can be designed to prevent buildup behind the ball.

Full Bore Ball Valves

Full bore ball valves have an oversized float with an orifice that is the same size as the pipe. These valves are larger, so they are more expensive.

Reduced bore ball valves:

Known as reduced bore ball valves or standard ball valves, these valves have a smaller bore than the pipeline, so flow is restricted and pressure drops. These are usually used when flow is not a major issue. In addition, they are smaller and more cost effective than full-pass valves.

Chamber Filled Ball Valves

A constant flow of gas or liquid through a ball valve can cause buildup behind the ball. Cavity-filled ball valves prevent this from occurring. This type of valve has a seat or housing that completely surrounds the floating ball to prevent buildup. They are typically used in systems where this buildup can lead to bacteria, i.e. brewing and food systems, or where materials can crystallize behind the ball like paint.

V-Orifice Ball Valves

Instead of a cylindrical bore, V-hole ball valves have a V-shaped bore or seat. Therefore, as the valve moves from closed to open, the narrower end of the V shape sits in front of the flow and more material can slowly flow through the valve as the wider portion of the V-shaped hole reaches the pipe. This results in greater precision and more control than other styles.

Buyer Tips

Choose the right valve for your pipe size; there are ball valves for all standard pipe sizes. Typically, the standard reduced flow ball valve is the most typical type of valve. In addition, you will need to select a valve with the correct threads. The most common options include female threads, where both pipe openings are male, or non-threaded valves, which are designed for PVC piping and other non-threaded materials.
