The GSDH8 is both the highest pressure and the highest flow (Cv) model within the GS General Services series. NPT and BSPP threaded connections are standard but many other options are available including ANSI and DIN flanges. The GSDH8 is often used to control the discharge pressure from high pressure pumps used in chemical injection or chemical dosing applications. The high speed response of the GS series maintains the pressure accurately despite fluctuating system demands and valves opening/closing.
The GSD8 is also used in industrial scale electrolysis or electrolyzer pressure control to control the gas streams produced in water electrolyis for Hydrogen production.
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.
