GSDM4 General Service Back Pressure Regulator

The 1/2″ GSDM4 back pressure regulator is intended for services with higher pressures than the GSD4. The GSDM4 can be rated for operating pressures up to 750 psig / 52 bar(g). PEEK, PTFE/Glass, or Metal Diaphragms are commonly used for applications in this pressure range.

GS Series

The GS ‘General Services’ is a family of back pressure regulators useful for gas, liquid, or mixed gas & liquid service. The GS design uses multiple parallel internal 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 the back pressure. The GS series is the ideal size for accurate control in pilot plant or manufacturing scale applications.
