Pressure regulators control the incoming pressure of water, steam, gas, and other media to a desired level. General purpose pressure regulators maintain consistent fluid pressure supplied to downstream equipment and processes. Water pressure regulators maintain consistent water pressure levels throughout commercial and industrial facilities. Steam pressure regulators adjust the input pressure of steam to achieve a specific output pressure for downstream equipment. Gas pressure regulators adjust the input pressure of gas to achieve the required output pressure to operate instruments and appliances in commercial and residential areas. Cryogenic service pressure regulators are used with extremely cold, cryogenic fluids. Corrosive and ultra-pure liquid regulators handle harsh and corrosive liquids as well as ultra-pure liquids that contain no contaminants or additives. Automatic control regulators provide more precise control of fluid pressure than standard pressure regulators.
