A dual plate check valve is a type of check valve that consists of two spring-loaded plates that are hinged together and positioned within the valve body. When the fluid flows in the forward direction, the plates are pushed open, allowing the fluid to pass through. However, when the fluid flows in the reverse direction, the plates are forced shut by the pressure of the fluid, preventing backflow. This type of valve is commonly used in applications where backflow prevention is critical, such as in water treatment plants, oil and gas pipelines, and chemical processing plants.

Recently, we sedelon produced a large size dual plate check valve!
