The GSD8 is the largest of the GS Series, and is available with standard female 1″ NPT ports. Custom connections include BSPP or flanges. Available in pressures up to 15 Bar, the GSD8 is also extremely useful in low pressure applications such as tank blanketing or tank padding. The GSD8 may also be used to control the back pressure of low pressure inert gasses used to shield a welding process.

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 your back pressure. The GS series is ideally sized where accurate control is needed in pilot plant or manufacturing scale applications.
