Butterfly valves are important devices that are designed to offer improved flow control within a system. Its design includes a metallic disc that rotates a quarter-turn motion at a time around a fixed-stem axis. The 90-degree turn provides quick response control between open and closed positions. Additionally, the disc is sized to be equivalent with the internal diameter of the adjoining pipe to offer full-control capability.

In order to meet specific flow control functionality in various industrial applications, butterfly valves are manufactured in different sizes and design configurations. If you are interested in gaining more knowledge and valuable insights about butterfly valves then make sure to visit this year’s ADIPEC 2022 where Dutco Tennant LLC will be exhibiting its quality range of butterfly valves starting from 31st October 2022.

Now, before you go to the event, here’s a quick rundown of all the pros and cons that a butterfly valve offers. Keep reading till the end to find out.

PROS

Compact & Lightweight Construction

Butterfly valves are ideal for use in several applications due to their lightweight construction and offer reasonable flow control available in a compact design. Users generally need to use a metal-seated valve for applications handling extreme fluid processing.

On the contrary, a soft-seated butterfly valve is the most suitable choice for applications dealing with low pressures and temperatures. Butterfly valves commonly have discs that take up limited space all the while offering sufficient strength in most pump systems.

Fast & Effective Operations

The 90-degree turning radius of the butterfly valves enables for rapid sealing upon actuation. This results in more accurate flow control with minimal effort for turning the valve on or off. 

There are different butterfly valves that are to be considered, including zero-offset, double-offset, and triple-offset. The pressure within the system will usually determine which type of valve you need. The higher the offset, the more pressure the valve can handle.

Simple & Inexpensive

Butterfly valves do not involve any complicated design and are in fact very simple in design having minimal requirement for maintenance. They are also easy to install and operate. 

Moreover, they are generally less expensive by a lot in comparison to a ball valve of the same size. They don’t have the requirement for much torque to effectively operate and can also be automated for carrying out energy-efficient operation.

CONS

Non-Resistant to Corrosive & Viscous Fluids

Viscous and corrosive fluids tend to scour against the butterfly valve’s disc during operation. This can lead to swift deterioration of the disc and even loss of sealing pressure. This is why butterfly valves are not the preferred choice in applications where viscous or corrosive liquids are processed.

No High-Pressure Throttling

A butterfly valve has restricted opening between 30-80 degrees. This makes them ideal for use in low-pressure throttling applications.
