How to Select and Size Safety Valves and Pressure

The set pressure, which is measured in pounds per square inch (PSIG), is the pressure at which a safety or pressure relief valve opens. The set pressure of the valve must not exceed the maximum allowable working pressure (MAWP) of the boiler or other vessel. What this means is that the valve must open at or below the MAWP of the equipment. In

Pressure Reducing Valve - an overview | ScienceDirect

The most commonly used device for regulating gas flow in pipelines is the pressure reducing valve.These valves provide a mechanical constriction in the pipe, much as an orifice plate reduces the cross-sectional flow area, thereby effecting a local pressure drop in the flow. Commercial reducer valves are much more sophisticated than orifice plates, but they work on basically the same principle.
