Automatic Recirculation Valve -- Pump Minimum Flow WCB
Combined automatic recirculation valves that integrate a main line check valve with a modulating bypass control element to maintain boiler feed pump minimum flow during low-demand periods. Protects centrifugal pumps from overheating, cavitation, and vibration at low flow. Single-body design eliminates separate check valve + control valve + orifice plate assembly.
