Pressure-Reducing, Dome-Loaded

Pressure-Reducing Dome-Loaded Regulators

Pressure-Reducing Dome-Loaded Regulators

  • Minimize droop by balancing outlet pressure with dome pressure
  • Enable dynamic pressure control to provide more consistent downstream pressure as flow demand vary
  • Maintain control safely by balancing the dome pressure against the force of the outlet pressure
