The primary function of a gas pressure reducing valve is to decrease and stabilize the pressure of a gas entering a system. When gas flows from a high-pressure source, such as a gas main, to a lower-pressure distribution system, the PRV adjusts the pressure to a predetermined level suitable for the downstream equipment. The valve operates on the principle of a diaphragm mechanism, where changes in downstream pressure result in adjustments to the valve opening, maintaining the desired output pressure.

While natural gas is a fossil fuel, it produces approximately 50% fewer carbon dioxide emissions than coal when burned for electricity generation. This characteristic positions it as a transitional fuel that can support the shift toward a low-carbon economy. However, the extraction and distribution of natural gas are not free from environmental concerns. Methane, the primary component of natural gas, is a potent greenhouse gas that can significantly contribute to global warming if released into the atmosphere during production and transportation.
