Swagelok® Back-Pressure Regulators, Dome-Loaded
Maintain control safely with the fixed gas dome design of a back-pressure, dome-loaded regulator.
Request More InformationBack-pressure dome-loaded regulators control inlet or upstream pressure to protect sensitive equipment from costly damage. They enable dynamic pressure control to provide more consistent upstream pressure as flow demands vary. Control is maintained safely with the fixed gas dome by balancing the dome pressure against the force of the inlet pressure.
