One of the most common applications of decompression equipment is in deep-sea diving. Divers who operate at depths greater than a few meters are subject to increased pressure from the water above them. If they were to ascend too quickly without allowing their bodies to adjust to the changing pressure, they could experience decompression sickness, also known as the bends. This potentially fatal condition is caused by the formation of nitrogen gas bubbles in the bloodstream and can lead to a variety of symptoms, including joint pain, dizziness, and even paralysis.

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.
