In the fuel gas system to a hot oil heater, what does the acronym PRV stand for?

The acronym PRV in the context of a fuel gas system to a hot oil heater stands for Pressure Regulating Valve. This valve plays a crucial role in controlling and maintaining the pressure of the gas flowing to the heater. By regulating the pressure, it ensures that the hot oil heater operates efficiently and safely, preventing potential damage or hazardous situations that could arise from excessive pressure.

The Pressure Regulating Valve adjusts the flow of gas to maintain a desired set point, thus optimizing the performance of the heating system. Additionally, ensuring that the pressure remains within the operational limits is essential for safety and effective operation.
