South American Valve is a leading Dual Plate Check valve manufacturer in Brazil. A Dual plate check valve is a type of non-return valve designed to allow fluid flow in one direction while preventing backflow. It features two spring-loaded plates or discs that pivot on a central hingepin. When fluid flows in the forward direction, the pressure causes the plates to swing open, allowing unobstructed passage. When the flow stops or reverses, the springs push the plates back to the closed position, sealing against the valve seat and preventing backflow. This design provides a quick and reliable response to flow changes, making it suitable for various applications, including water supply systems, oil and gas pipelines, and industrial processes.
South American Valve is a leading Dual Plate Check valve manufacturer in Brazil. The dual plate check valve offers several advantages over traditional single-disc check valves. Its compact and lightweight design reduces installation space and weight, which is particularly beneficial in large-scale industrial systems. The use of two plates provides a more balanced closure, reducing the impact forces and wear on the valve components, thereby extending the valve's service life. Additionally, the valve's low-pressure drop and efficient flow characteristics enhance system performance and energy efficiency. The dual plate check valve's versatility and robust construction make it a popular choice for preventing backflow in a wide range of fluid handling systems.
How does it work?
A dual plate check valve operates by utilizing two spring-loaded plates that pivot on a central hinge pin. When fluid flows in the forward direction, the pressure pushes the plates open, allowing the fluid to pass through with minimal resistance. If the flow stops or reverses, the springs quickly push the plates back to the closed position, sealing against the valve seat to prevent back flow. This mechanism ensures a swift and reliable response to changes in flow direction, maintaining unidirectional flow and protecting the system from potential damage caused by reverse flow.
