Ball valves and butterfly valves are the two most common types of rotary valves. It only need a quarter-turn to turn on or turn off both valves. However, there are certain functions where a ball valve is better than a butterfly valve.

First of all, ball valve provides a perfect seal. When the valve is completely closed, there will be no leakage. More importantly, the ball valve can rotate regardless of the pressure from the supply line. What’s more, as long as it is fully open, it will not reduce the pressure of the fluid in the pipeline.

Ball valves are primarily used to control high-pressure liquid and gas lines. This is because ball valves do not cause any pressure drop or impede fluid movement when fully open. What is worthy to be noted that they are primarily used in applications where the inside diameter of the pipe is less than or equal to 6 inches.

Ball valves have no trouble in high-pressure applications. In addition, when ball valves are used in high-pressure applications, a pressure balancing scheme is not required. This is not possible with butterfly valves.

Ball valves have a simple structure. They are also smaller and lighter compared to many other types of valves. Ball valves have a very flexible soft seal, which makes it easy to operate. And ball valves have the lowest fluid resistance compared to all other types of valves.

You can use the valve for many years without any damage due to leakage. In other words, this means that the valve is reliable and cost effective in the long term. This valve can be designed to withstand extremely high pressures. In fact, you will recognize that high-pressure systems often have ball valves fitted internally.

There can be multiple ends in a ball valve. It allows many combinations of ports. If you are thinking of purchasing a ball valve, you can consider these advantages before your purchase.
