ASME swing check valve

Overview：

A check valve, also known as a one-way valve, is a type of valve that automatically opens and closes based on the flow of the medium and its own pressure. Its core function is to prevent the backflow of the medium in the pipeline, while avoiding pump reversal, pressure shock, or system failure caused by medium backflow. Check valves do not require manual operation. They push open the valve disc through the forward flow of fluid, and automatically close when the reverse flow occurs, achieving "one-way conduction and two-way shut-off".
