Swing Check Valve Fire Protection

Ductile Iron swing check valve A swing check valve, also known as a tilting disc check valve, is a type of valve used to regulate the flow of fluids in a system. It is designed to prevent the backflow of fluid by automatically closing when the flow of fluid is reversed. The valve operates by utilizing a swinging disc, which moves freely within the valve body. When fluid flows in the desired direction, the disc swings open, allowing the flow of fluid to continue unobstructed. However, when the flow of fluid is reversed, the disc swings closed, preventing the backflow of fluid.
