AV Series, Auto Re-Circulation Check Valve
Auto Re-circulation Check Valve has two functions: a mini flow valve and a check valve that always maintain the minimum flow of the centrifugal pump.
The Bypass function is performed by mechanically linking to the main check valve, and as the flow rate required by the process decreases, the pressure acting on the disc spring decreases, and as the disc descends toward the seat, thus the bypass port opens proportionally to form a min flow.
