Introduction to Butterfly Check Valve
A butterfly check valve is a type of valve that allows fluid to flow in one direction and prevents backflow. It consists of a disc that is hinged at the center of the valve body. When the fluid flows in the forward direction, the disc is pushed open by the fluid pressure. When the flow stops or reverses, the disc closes due to gravity, the back - pressure of the fluid, or a combination of both. Butterfly check valves are widely used in various industries such as water treatment, oil and gas, power generation, and chemical processing because of their simple structure, low cost, and relatively small installation space requirements.
