Rate of Flow Control Valve 

The rate of flow control valve shall function to control or limit the flow rate, regardless of fluctuations in upstream or downstream pressure.

The OCV 120 has a wide range of applications – anywhere the flow rate must be controlled or limited. Typical examples include:

  • Pump systems
  • Fuel metering systems


  • Controls or limits flow to a predetermined rate
  • Built-in orifice plate for sensing flow rate
  • Extra-sensitive differential pilot
  • Flow rate is adjustable with single screw
  • Adjustable response speed
  • Can be maintained without removal from the line
  • Factory tested and can be preset to your requirements
