Stainless Steel Rate-of-Flow Control Valve with Pressure Reducing Feature

951GS (Globe) and 951AS (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 reduce a fluctuating higher upstream pressure to a constant lower downstream pressure. The Orifice Plate is factory calibrated based upon minimum, maximum, and continuous flow rate requirements.


  • Automatically limits flow rate to a constant, adjustable maximum
  • Throttles to reduce high upstream pressure to constant lower
  • Orifice Plate Assembly is remote mounted (field installed)
  • Lightweight Stainless Steel construction reduces corrosion, diaphragm wear, and labor frequency and costs
