In recent years, advancements in technology have further increased the efficiency and reliability of natural gas production and transportation. Techniques such as hydraulic fracturing, or fracking, have enabled the extraction of natural gas from previously inaccessible reserves, leading to a surge in production and lower prices. Additionally, advancements in liquefied natural gas (LNG) technology have expanded the global market for natural gas, allowing for the transport of gas over long distances and enabling access to new markets.

The operation of a PRV is based on a simple yet effective mechanical principle. When the inlet pressure exceeds the setpoint of the valve, the internal mechanism adjusts to reduce the pressure to the desired level. Typically, this involves the use of a spring-loaded diaphragm or piston that moves in response to changes in pressure. As the upstream pressure increases, the diaphragm is pushed against the spring force, causing the valve to partially close until the outlet pressure stabilizes at the preset value.
