The Pressures Involved

It is in this instance that a ball valve may be considered a better option due to the valve always being able to open easily despite any pressure being placed upon it. The butterfly valve on the other hand can be difficult to turn as part of the disk will always have to fight against a flow of gas/liquid.

How They Function

A ball valve works by allowing the hole to be open, blocked, or open partially to regulate the flow of gas / liquid while a butterfly valve uses the disk to either allow the flow of gas/liquid through it or to block it completely.

The Design

The main difference between the two types of valves is that they look different. The ball valve is essentially a ball that has a hole going right through it whilst a butterfly valve consists of rotating shaft that has a disk mounted onto it. Of course, what they look like should not be a reason to choose one over another but it is important to know.

Their Best Uses

Because ball valves are able to offer better sealing which makes it an ideal choice for using with gases. Butterfly valves may not be able to completely seal in gasses which might be a danger in some industries.

Butterfly valves are cheaper than that of ball valves and are easier to maintain. It is for that reason that they are frequently used on large-scale projects that involve the regulation of water streams.
