Cryogenic service pressure regulators control and maintain consistent fluid pressure supplied to downstream equipment and processes. When the pressure of cryogenic fluids flowing through the inlet port is too high or low, the valve will open or close to meet the required outlet pressure, measured in pounds per square inch (psi). These regulators are constructed with materials that withstand harsh environments and are used with extremely cold media such as liquid oxygen, nitrogen, argon, and other cryogenic fluids.
