Swagelok® Pressure-Reducing Regulators, Dome-Loaded

Pressure-reducing, dome-loaded regulators can meet the needs of a variety of pressure, temperature, and flow conditions.

Request More Information

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, and maintain control safely by balancing the dome pressure against the force of the outlet pressure.
