As named these valves has application of creating flow in one direction. While if the flow is in reverse direction the valve does not allow the flow. They are also known as Check Valves. In hydraulic field high pressure NRV is very essential. This has benefit by elimination of back pressure. These are manufactured from single bar stock to avoid failure of valves.
