In a piping system, a Butterfly Valve is a type of valve that is used to control the flow of fluid. It is frequently used in situations where a tight shutoff is not necessary but fine flow rate control is. This is perfect for use in applications with limited space because it is lightweight and compact as well. Butterfly Valve has the benefit of only requiring a small amount of force to operate, making them simple to open and close. Cast iron, stainless steel, and PVC are just a few of the materials that are used to make these valves.
