A typical PRV consists of several key components the inlet and outlet ports, a diaphragm, a spring, and an adjustment knob or screw. The diaphragm is crucial as it senses pressure changes; when the downstream pressure rises above the set point, the diaphragm compresses the spring to close the valve partially, restricting the flow of gas. Conversely, if the downstream pressure falls below the set point, the spring expands, opening the valve to allow more gas flow.

In addition to safety, the regulator plays a significant role in energy conservation. By maintaining a constant pressure, it ensures that gas appliances run efficiently without wasting fuel due to excessively high or low pressures. For instance, a gas furnace operating at too high a pressure might heat up a room faster than necessary, leading to energy waste. Conversely, an appliance starved of gas due to low pressure will struggle to function effectively, consuming more gas in the process.
