1/12 · Non-return style regulators are characterized by their lack of a fuel return line from the regulator back to the fuel tank. With a blocking style regulator, fuel enters through the inlet port (A), travels past the fuel control valve (B), and then is distributed through an outlet

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.

IGEM/G/10 - Non-return valves. This document is largely based upon the original requirement for NRVs as agreed between British Gas and Energy Utilities Alliance, as published in IM14 in 1989.
