Product Overview
The R1480 is a self-acting regulator: it needs no external power or pilot supply. A spring-loaded diaphragm actuator senses downstream pressure and positions the valve plug to hold that pressure within close limits as demand changes.
The packless gland design removes the stem packing as a leak path and source of friction. Double seat bodies are standard; balanced and single seat constructions are available where a lower capacity is needed from a given body size.
It is suitable for oil, water, air, steam, gases or any fluid compatible with the materials of construction.
