High Flow Precision Regulator

HIGH FLOW PRECISION REGULATOR FOR PANTOGRAPH SYSTEMS

CUSTOMER CHALLENGE

Pantograph systems are expected to work harder as train manufacturers continue to develop faster trains. If the pantograph is detached from the wire arcing can occur, reducing the life of the wire and carbon strip.

NORGREN SOLUTION

Norgren’s LR27H high flow precision regulator is a fast response, high flow precision regulator which enables the Pantograph to respond to the height variations on the electric overhead lines.

  • Fast response
  • Quiet
  • Performs within temperature requirements
  • Stable
  • Accurate controlled adjustment
  • Low air consumption

The pressure regulator is the heart of the Pantograph system, as it regulates and maintains the force of the carbon strip onto the overhead wires (typically 60N).  As the wires are mounted between supports, the pantograph needs to extend and retract with the height variations of the wires.  The faster the train, the faster the reaction time

The Norgren solution provides an unrivalled overall performance with rapid, quiet and stable operation across a wide temperature range.
