GSDM8 General Service Back Pressure Regulator

The 1″ GSDM8 extends the pressure range above the standard GSD8 to a maximum operating limit of 500 psig / 34 bar(g). It can be used to control pressure in pilot scale chemical reactors, such as in active pharmaceutical ingredients or petroleum research industries. It is also frequently used in electrolyzer pressure control in the hydrogen industry. Follow the “Applications” tab for more application ideas. The standard stock body material is dual-cert SS316/SS316L, and is also available in Hastelloy C276 or other custom alloys. For higher pressures, a GSDH8 is also available to control pressures up to 2100 psig / 145 bar(g).

GS Series Back Pressure Regulators

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

Equilibar GS Series units are 1:1 dome-loaded, meaning that a gas or air “pilot” pressure 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.
