Introduce

Flange butterfly valve is a type of valve used in industrial and commercial applications to regulate the flow of liquids, gases, and other materials. It is designed with two concentric metal discs – or “butterflies” – connected to an open stem which passes through the disc center. The stem turns operating the two discs as they rotate simultaneously either open or closed due to the mechanical connection between them. This allows for precise control over flow rate adjustment by slowly opening and closing the valve.

Function

They provide reliable shutoff capability due their quarter turn operation principle without requiring excessive torque since only minimal pressure is needed for operation making them ideal solutions for many industries such as water treatment centers, food processing plants etc.. In addition their versatility also makes them suitable for many different types of applications like controlling air conditioning systems in factories, regulating gas lines at home etc.
