01
Use a centrifugal recirculation pump with a filter and diaphragm-actuated control valve to maintain detergent flow.
02
Provide a solenoid-actuated WFI supply valve with check valve to prevent backflow into the WFI storage tank.
03
Instrument each loop with flow transmitters and shared controllers for independent flow control.
Reusable for any wash-tank recirculation P&ID where a heated or ambient detergent loop and a clean rinse supply are required, such as CIP, parts washers, or vial washers.
