What is a Butterfly Valve3?

A butterfly valve is a quarter-turn rotary valve that is used to regulate flow in a pipeline. It has a circular disc shaped closure mechanism, which is mounted in the center of a pipe. This valve is designed so that a single quarter turn is all that is required to open or close it. As the disc turns within the valve body, the valve opens and closes, similar to the way a butterfly flaps its wings.

Why Are Butterfly Valves Used?

Butterfly valves are typically used to shut off or regulate flow in a pressurized system. The butterfly valve’s design makes it particularly useful when space is limited, since its disc only requires a quarter turn to regulate flow. In addition, its light weight and low torque make it easy to open and close. They are also cost effective and durable, making them a popular choice for many applications.

How Does a Butterfly Valve Work?

Butterfly valves come in many different types. These include wafer, lug, and flanged versions. Wafer butterfly valves are designed for simple installation and are often used for low-pressure applications. Lug butterfly valves are designed for heavier installation and are often used for higher pressure applications. Flanged butterfly valves are designed for permanent installation and can be used for a variety of applications.
