Differential Pressure Control Valve 

The differential control valve shall function to operate on a differential between two pressure points, where a decreased differential shall cause the valve to close. The valve operates on/off based on the pressure difference between two points in a system. Typical examples include:

  • LPG metering systems to prevent flashing
  • Metering systems as an air eliminator shut-off valve
  • Valve opens on an increasing differential; closes on a decreasing differential
  • Operates over a wide flow range
  • Pressure differential is adjustable with a single screw
  • Can be maintained without removal from the line
  • Adjustable response speed
  • Factory tested and can be pre-set to your requirements
