Bundor Valve replied: The one-way check valve and dual plate check valve are basically the same thing, but there are some differences: the one-way check valve is control type check valve, and the dual plate check valve is a non-control type check valve. That means the one-way check valve is used in the application of pressure, and the main function is to maintain the pressure of the pipeline. Although the dual plate check valve can also provide this function, it is mainly used to control the back flow of the medium and does not require pressure. That means the one-way check valve has a tendency to control, and the dual plate check valve is a purely natural function.
