Ball valves – How to choose the right model

Choosing the right ball valve may seem simple, but there is actually a lot to consider. Should you have a 2-way ball valve for easy shut-off, or do you need a 3-way ball valve to control the flow in different directions? Materials, sealing solutions and area of application also play a major role. Here we go through the most important things you need to know to find the best solution for your needs.

What is a ball valve and how do they work?

A ball valve is a shut-off valve that regulates the flow of liquids or gases using a rotating ball. When the ball is turned 90 degrees, it opens or closes the flow. This makes the ball valve a popular choice for fast and reliable flow control in everything from water and oil pipes to industrial systems.

Which type should you choose?

There are different types of ball valves, and the choice depends on how you want to control the flow.

Ball valve 2-way – The most common type, with an inlet and an outlet. Perfect when you just need to open or close a feed. kunskapsbank Produkter ventiler kulventiler kulventil_2-vags_axel_larsson

Ball valve 3-way – Has three ports and is used when you want to direct the flow in different directions, such as switching between two pipes or mixing different liquids. kunskapsbank Produkter ventiler kulventiler kulventil_3-vags_axel_larsson

In addition to this, there are also differences in materials and construction. Should the valve be able to withstand high pressures and temperatures? Then carbon steel or a stainless steel variant can be a good choice. For more demanding environments, advanced materials such as Super Duplex are available, while a brass valve works great in simpler applications.

How to find the right ball valve

To make a good choice, you need to think about the following.

Which medium should flow through the valve – water, oil, gas or chemicals?
Pressure and temperature – some materials can withstand more than others.
Sealing material – PTFE seals provide good durability, while metal seals can withstand extreme conditions.
Flow control – Do you only need an on/off function, or do you want to control the flow in multiple directions?

Common mistakes to avoid

Many people choose the wrong ball valve by

Not adapting the material to the medium.
Underestimate the importance of the right sealing solution.
Forget to check pressure and temperature limits.
Fail to inform about important certificates and documentation that are required.
Do not specify whether the valve should be automated or operated manually.

Find the right ball valve for your application

Choosing the right ball valve is all about understanding your specific needs and ensuring a model that delivers both performance and durability. A well-matched ball valve can improve operational reliability, reduce maintenance and optimise flow control in your facility.
