An automatic recirculation control (ARC) valve is a multi-functional pump protection valve engineered to automatically ensure a minimum flow rate passes through a centrifugal pump at all times. Operating entirely on fluid dynamics without external power or instrumentation, it combines a main-line check valve, a flow-sensing mechanism, and a bypass control loop within a single body. When downstream demand drops below critical levels, the main disc lowers, opening the modulated bypass trim to recirculate a portion of the fluid back to the suction tank or deaerator, preventing severe pump cavitation, overheating, and mechanical vibration. Power plant operators and refinery procurement networks can prevent catastrophic pump burnout and optimize thermal efficiency by importing certified automatic recirculation control valves directly from specialized manufacturers in China via our advanced B2B digital marketplace.
