Gas Back-Pressure Regulators: Definition, Features, Materials & Specifications

Definition of Gas Back-Pressure Regulator

Gas back-pressure regulators are used for pressure regulation in medium and high-pressure systems under small to medium flow conditions, with a maximum control pressure of up to 10000 psig / 690 bar. The piston assembly provides highly sensitive pressure relief when the system is overpressurized, and the back-pressure regulator is suitable for gas or liquid service.
