What Are Butterfly Valves and How Do They Work?
One of the most popular plumbing valve options today is the butterfly valve. It’s a kind of quarter-turn valve that uses a disc placed inside the center of the pipe to control or block the flow of liquid that passes through it. Operation is pretty straightforward as one just has to turn the lever or wheel on the top of the valve to turn the disc and shut down the water flow.Because it is simple to use, easy to install, lightweight, durable, and inexpensive (as compared to other valve types), butterfly valves are used for a lot of applications that require control of liquid flow, including petroleum pumps and commercial and residential plumbing.This type of valve is named as such because the disc opens and closes (much like a butterfly) when the lever on top is turned.
