Features

This high flow precision regulator includes:

  • Adjusting Knob
  • Diaphragm Design for Good Repeatability, Response and Sensitivity
  • Balanced Poppet
  • Two Full Flow Gauge Ports
  • Precise Regulation
    Senses a decrease in Downstream Pressure as small as 1/4" of Water
  • High Flow Capacity
    Flows of 80 SCFM Attainable with Minimal Drop
  • Stable Output
    Dampening Action of Aspiration Tube makes Regulator
    Insensitive to Changes in Flow
