Model 114-3 Hydrant Control Valve For Pantograph Systems

Model 114-3 Hydrant Control Valve For Pantograph Systems

The OCV Model 114-3 is a control valve specifically designed for aircraft refueling service. Known as either a refueling or a hydrant control valve, it is the typical control valve used on pantograph refueling systems. It performs the following functions:

  • Opens and closes via hydraulic deadman control.
  • While open, modulates to control downstream pressure at a predetermined set point.
  • Closes rapidly to prevent undue pressure buildup due to a rapid reduction in demand.


  • Hydraulic deadman control
  • Pressure reducing pilot senses valve outlet or pressure compensating venturi
  • High capacity surge control minimizes pressure buildup on reduction of flow
  • Opening speed control
  • Automatically opens for downstream thermal relief or defueling
  • Equipped with visual indicator to monitor valve position
  • Can be maintained without removal from the line
  • Factory tested and can be pre-set to requirements
