The 1/4″ GSD2 is one of the most popular back pressure regulators because it is useful for larger research applications and has high enough capacity for small industrial gas and liquid systems.

GS Series

The GS General Service is a family of back pressure regulators useful for gas, liquid, or mixed gas & liquid service. The General Service design uses Equilibar’s unique multiple orifice, direct diaphragm sealing technology to control back pressure with great accuracy where high temperatures, aggressive chemicals, mixed gas/liquid phase media, or other demanding conditions exist. The GS series is a dome loaded pilot operated design. Pilot pressure may be provided by a remote manually adjusted set point regulator or with an electronic pressure regulator to allow automated or closed loop control of your back pressure. The GS series is ideally sized where accurate control is needed in pilot plant or manufacturing scale applications.

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