ARC Control Valve

An ARC control valve (Automatic Recirculation Control valve) is a highly sophisticated, multi-functional safety valve engineered specifically to protect high-pressure centrifugal pumps from overheating, cavitation, and serious mechanical damage during low-flow process conditions. Acting as a flow-sensing check valve, it automatically bypasses a calibrated minimum flow of liquid back to the suction tank when downstream process demand drops below a safe limit, while remaining fully closed during normal high-flow operations. Conforming to standards like ASME B16.34, API 6D, and standard pump protection codes, these critical self-operating valves are primary specifications in boiler feedwater pumps, oil refinery loading pumps, and high-pressure liquid pipelines, allowing mechanical utility engineers to maximize pump service life and reduce system energy consumption by importing certified ARC control valves directly from specialized manufacturers in China via our advanced B2B commercial platform.
