The GSD3 back pressure regulator provides stable control of liquids and gases in many industrial applications. One popular application is that of automotive fuel cell testing systems, where the 3/8″ ports are ideally sized for rapid control of gasoline or diesel fuel pressure. For this reason, this model is commonly available in both NPT and BSPP threads.
The GS General Service is a family of back pressure regulators useful for gas, liquid, or mixed gas & liquid applications. The general service design uses Equilibar’s unique multiple orifice with 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.
