Automatic Recirculation Valve

Automatic Recirculation Valves protect centrifugal pumps during low loads


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 it’s seat and causes the bypass bush to open a bypass flow path. The pump minimum flow rate is thus reached and maintained.
• Proprietary Cv sizing for 3 phase flow
• Continuous acceleration body design moves flashing from the body into the vessel, preventing cavitation as well as deposits in the valve
• Integral plug and stem
• Control characteristics optimisation using the SchuF Bell x³ Control Curve (linear and equal % also available)
• Dead space free control
• Unique patented spindle protector
• Choice of inlet angle, 90, 45, or 60 degrees
