GSDH4 General Service Back Pressure Regulator

The GSDH4 is the highest pressure version of the 1/2 inch port models. The GSDH4 is often used to control the discharge pressure of high flow hydraulic pump recirculation loops when high accuracy and resolution are needed.

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 orifices 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 manually adjusted set point regulator or with an electronic pressure regulator to allow automated or closed loop control of your back pressure. The pilot regulator may be located remotely or at the process depending on design requirement. 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.
