Description

Minimum Flow or Automatic Recirculation Valves automatically protect centrifugal pumps during low load operation. As the pump’s load drops below a preset flow rate, the valve’s disc moves towards its seat and causes the bypass bush to open a bypass flow path. The pump minimum flow rate is thus reached and maintained.1 inch (DN 25) to 10 inch (DN 250) pumps and up to ASME 2500# pressure class. Other options on demand.
