GSD3 General Service Back Pressure Regulator

The GSD3 back pressure regulators is useful for larger research applications and has high enough capacity to control fluid systems in small industrial or pilot plant facilities. One popular application automotive fuel pump testing systems, where the 3/8″ ports are ideally sized for rapid control of gasoline or diesel fuel pressure.

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.

Contact an application engineer for help finding the right back pressure regulator for your process.
