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.

2018-9-21·Boilers requiring preheated oil also require the temperature to be monitored. Flame proving for oil burners also is required, though the allowable time for flame initiation and failure is slightly longer than for gas boilers, depending on ignition type and firing rate. Combustion-air interlocks are similar to those of gas-fired units.
