Pressure-Reducing, Dome-Loaded
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
