Product Description
GSD4 General Service Back Pressure Regulator

GSD4 General Service Back Pressure Regulator

The GSD4 is popular for fuel cell testing applications, liquid spray control applications, and many others. The 1/2″ ports are available standard in NPT, but are also available in BSPP, SAE, and flange. A standard SS316/316L body may be mated to various diaphragm material options including PTFE, PEEK, and thin metallic foils to match specific application chemical media and temperature requirements.

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.
