Application: Automatic recirculation valves protect centrifugal pumps against overheating, excessive noise, instability and cavitation during low flow conditions. If the flow through the pump falls below a certain level a bypass system opens and fluid will be recirculated providing the required minimum flow through the pump.
Operation: The main flow positions the check valve at a certain point. The stem of the check valve transmits the motion via a lever to the bypass. The bypass controls the bypass flow in a modulating way and reduces the pressure to bypass outlet level. The full minimum flow is bypassed when the check valve is seated. The bypass is fully closed when the check valve is in its upper position thereby allowing full flow to the system with established minimum flow.
