Crafted with precision, this check valve guarantees enhanced durability and performance, making it an essential component for systems that require a non-return flow. Its rugged construction ensures longevity, and it is available in various sizes to meet a range of application requirements.  

A Double Plate Check Valve is a type of non-return valve that is designed to prevent backflow in pipelines. It is sometimes referred to as a Dual Plate Check Valve or Duo Check Valve.The valve consists of two spring-loaded plates that are hinged on a central pin. When there is flow in the forward direction, the plates are pushed open, allowing fluid to pass through. When the flow decreases or stops, the plates are closed by torsion spring action, preventing reverse flow.Compared to traditional swing check valves and lift check valves, Double Plate Check Valves are generally stronger, lighter in weight, and smaller in size. They also offer the benefits of no water hammer and non-slam simultaneously, making them an efficient and effective choice for many applications.Double Plate Check Valves are commonly used in industries such as oil and gas, water treatment, chemical processing, and power generation. They are available in a variety of materials, sizes, and designs to suit different pipeline applications.

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.
