Single Plate Check Valve

South American Valve is a reliable manufacturer of Single Plate Check Valves in Venezuela. Single Plate Check Valve is a type of check valve, also known as a non-return valve or one-way valve, that allows the flow of fluid in only one direction and prevents backflow. It consists of a metal or plastic disc or plate that is hinged or mounted on a spring, which is held against the valve seat to block the flow of fluid when the pressure in the upstream direction drops or reverses. When the pressure in the upstream direction increases and exceeds the pressure in the downstream direction, the disc or plate is lifted off the valve seat, allowing fluid to flow freely in the desired direction. The disc or plate will return to its closed position when the pressure drops or reverses, thus preventing the backflow of fluid. Single Plate Check Valves are commonly used in various applications, including pipelines, pumps, compressors, and water systems, where backflow prevention is necessary to protect equipment and ensure the safe and efficient operation of the system. They are compact, lightweight, and easy to install, making them an ideal choice for many industrial and commercial applications.
