Ductile Iron Rate-of-Flow Control Valve with Pressure Sustaining Feature

LF952GD (Globe) and LF952AD (Angle) Series is designed to automatically limit flow rate to a constant, adjustable, maximum by sensing differential pressure across a remote mounted orifice plate (field installed), and sustain a minimum upstream pressure. The Orifice Plate is factory calibrated based upon minimum, maximum, and continuous flow rate requirements.


  • Orifice Plate Assembly is remote mounted (field installed)
  • Automatically limits flow rate to a constant, adjustable maximum
  • Rate-of-Flow and Sustaining setpoints are separately adjustable
  • Throttles to maintain minimum upstream pressure
