NORGREN Pneumatic Pressure Regulator R73G, R73R



Pressure Regulator

  • Port Sizes : 1/4" 3/8", 1/2"
  • EXCELON design allows in-line or modular installation
  • Full flow gauge ports
  • Balanced valve design minimizes effect of variation in the inlet pressure on the outlet pressure
  • Standard relieving models allow reduction of downstream pressure when the system is dead-ended
  • Optional reverse flow models available for use downstream of directional control valves
  • Modular installations with EXCELON 72, 73, and 74 series can be made to suit particular applications
