Definition - What does Pressure Regulator mean?
Pressure Regulator is a valve that alters the flow of the gas or liquid at absolute pressure. It allows high-pressure fluid supply lines to be reduced to bearable pressures for various applications. There are diverse types of regulators such as rotameters, mass flow controllers, and flow meters. The primary function is to match the flow of the gas by the regulator located on the system. As the load flow is directly proportional to regulator flow, an increase in load flow increases the regulator flow and vice versa.
Petropedia explains Pressure Regulator
Pressure Regulators are commonly used in industrial applications. There are various processes carried out by the regulators, e.g., they regulate propane in gas drills and natural gas in heating furnaces. When choosing an appropriate Pressure Regulator, one must seek into some crucial factors like operating pressure ranges, flow requirements, materials, size, and weight constraints. The principal components of the regulators are spring-loaded poppet valve, diaphragm, and spring. Moreover, the accuracy can be measured by calculating outlet pressure versus flow rate. They are used in air compressors, gas powered vehicles, and the mining industry.
