Emerson Automation Solutions – TESCOM Regulators, Valves & Systems Datasheets for Gas Pressure Regulators

Gas pressure regulators reduce the pressure of a gas, as it passes through a cylinder or process line, to another piece of equipment. Regulators are not flow control devices. They are used to control delivery pressure only.
