Why Butterfly Valves are well suited as a fluid flow control valve

BM Engineering Supplies provide Butterfly valves to a wide range of customers from within the process market. Butterfly valves are seen as a lightweight and cheaper alternative to many other valve types, including ball valves.

The primary use for a Butterfly valve is as a shut-off valve, but they are also good for use as a fluid flow control valve in wastewater treatment, agricultural, and water applications. PIF takes you through the different types of Butterfly valve and the reason why they are so good as a fluid flow control valve.

What are the different types of Butterfly valves?

Each of the three different types of Butterfly valves are adapted to work with different pressures and usage. They include:

  • Zero offset Butterfly valves which have the lowest pressure rating and relies on the flexibility of rubber
  • Double offset Butterfly valves which are used in slightly higher-pressure systems which, by creating a cam action during operation to lift the seat out of the seal, produces less friction, reducing the tendency for wear and results in high performance
  • Triple offset Butterfly valves which are best suited for high-pressure systems.

Why are butterfly valves good for use as a fluid flow control valve?

One of the key features that promote Butterfly valves as a fluid flow control valve is that they are smaller and weigh less than the alternatives. Providing they are sized correctly, Butterfly valves can offer a wider control range than similar valves, such as globe or ball valves and take up less space.

As well as the size and weight advantages, Butterfly valves also have a higher capacity and lower flow restrictions. They are also the valve of choice for economical reasons as they offer lower installation costs. This is down to Butterfly valves being line size and not requiring pipework reducers.

Applications where Butterfly valves can be used as a fluid flow control valve

There is a wide range of applications for when Butterfly valves are ideal for use as a fluid flow control valve. They can be used for capacity lines on shops and perform well within slurry and water applications with high volume.

Some of the applications, where the different types of Butterfly valves that BM Engineering stock, can be used include:
Cooling water, air, gases and fire protection

  • Slurry
  • Vacuum services
  • High pressure, temperature water, and steam services
  • Compressed air applications
  • Compressed gas applications.
