How to Determine if Your Butterfly Valve is Open?

Butterfly valves differ from all the other valves in this post because not only can they be used as a shut-off valve, they can also be used as a regulatory valve. Inside the butterfly valve is a disc that rotates as you turn the handle. Butterfly valves can regulate flow by having the disc partway open.

Butterfly valves have a lever handle on the top that is similar to the ball valve. This handle both indicates if the flow is on or off, and can be used to turn the valve partway on by locking the disc in place. When the handle is parallel to the valve, it is closed, and when it is perpendicular to the valve, it is open.

Butterfly valves are suited for use in garden irrigation, and they are also commonly used in space-restrictive applications. They have a slender design that makes them ideal for tight-fitting spaces. Because of the disc inside, these valves are not the best to use in high-pressure applications as there will always be something in the way partially blocking the flow.
