GSD6 General Service Back Pressure Regulator

The 3/4″ GSD6 back pressure regulators (BPRs) are used to control pressure from the millibar (inches of water column) range up to 300 psig / 21 bar(g) in the stainless steel model. Maximum pressure rating will vary by body material and the details can be found in the GS Series brochure. Equilibar BPRs can also be configured for closed loop flow control for complex applications.

GS Series

The GS Series back pressure regulators are used for gas, liquid or mixed phase fluid control and are ideally sized for pilot plant or manufacturing scale applications. They range in port size from 1/4″ to 1″.

Back pressure regulators control their inlet pressure to regulate the upstream process by opening up only as much as necessary to hold back the desired pressure at the inlet.

The GS design uses Equilibar’s patented multiple orifice with direct sealing diaphragm technology to control back pressure with great accuracy even where high temperatures, aggressive chemicals, mixed gas/liquid phase media, or other demanding conditions exist.

Equilibar GS Series units are 1:1 dome-loaded, meaning that a fluid ‘pilot’ pressure (usually inert gas or air) must be supplied to the dome of the BPR equal to the desired inlet setpoint. This pilot pressure can be supplied by a manual pressure regulator or by an electronic pressure regulator for computer automation.

Contact an Equilibar application engineer with questions or to discuss your specific process requirements.
