Definition of non-return valve: The non-return valve permits the medium to flow in a single direction. The reason to fit the non-return valve is to make sure that the medium is flowing inside the pipe in the correct direction. It is dependent on the condition of the pressure. Otherwise, there can be a reversal in the flow direction.

Non-return valves are flow sensitive, and rely on the steam flow to open and close. The internal disc opens and allows the flow of steam through the valve. The disc will begin to close as forward steam flow decreases or is reversed, depending on the design.
