LF912GD

Ductile Iron Pressure Reducing and Sustaining Control Valve

The LF912GD (Globe) and LF912AD (Angle) Series is designed to automatically reduce a fluctuating higher upstream pressure to a constant lower downstream pressure regardless of varying flow rates, and throttle to sustain a minimum upstream pressure. The normally closed sustaining pilot remains open when upstream pressure is above the adjustable setpoint, and modulates toward a closed position if upstream pressure falls below the setpoint. As the sustaining pilot closes, fluid is directed into the main valve cover chamber, allowing the valve to modulate toward a closed position, raising upstream pressure. Normal pressure reducing operation resumes when upstream pressure is above the sustaining pilot setpoint, and downstream pressure is below the reducing pilot setpoint

Features

  • Throttles to reduce high upstream pressure to constant lower downstream pressure and to maintain minimum upstream pressure
  • Reducing and Sustaining setpoints are separately adjustable
  • Automatically reduces a fluctuating higher upstream pressure to a constant lower downstream pressure
  • Sizes 1 1/4 in. to 16 in. (32mm to 400mm)
