A cast iron duo plate check valve is a type of check valve used in piping systems to prevent backflow of fluids. It is called a "duo plate" check valve because it has two half-discs, or plates, that swing on a hinge to open and close the valve.The two plates are shaped like semicircles and are mounted on a hinge in the center of the valve body. When the fluid flows in the forward direction, the plates are pushed open, allowing the fluid to pass through the valve. However, when the fluid flows in the reverse direction, the plates swing shut, preventing the backflow of fluid.
The duo plate design provides a number of advantages over other types of check valves. For example, it is more compact and lightweight, making it ideal for use in space-constrained installations. Additionally, the swinging plates produce less turbulence and pressure drop compared to other designs, which can reduce energy costs and extend the life of the valve.Cast iron is a popular material choice for duo plate check valves due to its strength, durability, and corrosion resistance. Cast iron duo plate check valves are commonly used in water distribution, sewage treatment, chemical processing, and power generation applications.
