The operation of a pressure reducing valve is straightforward yet effective. Typically, the valve consists of a diaphragm that responds to the changes in pressure. When the inlet pressure exceeds the set point, the diaphragm moves, causing the valve to open and allow some fluid to escape, thereby reducing the pressure downstream. Conversely, when the outlet pressure drops below the desired level, the diaphragm closes, restricting flow and allowing pressure to build up. This automatic adjustment ensures that the downstream pressure remains constant, regardless of fluctuations in the upstream pressure.

The primary function of a gas pressure regulating valve is to maintain a consistent outlet pressure despite changes in inlet pressure or flow demand. This regulation is crucial because gas systems operate under various conditions, including fluctuations in upstream pressure due to changes in supply or consumption patterns. By automatically adjusting the valve position, GPRVs ensure that the pressure at the outlet remains within a safe and functional range. This not only protects downstream equipment from damage but also enhances overall operational efficiency.
