With 3/4 inch nominal ports and a maximum pressure rating of 3000 psig / 206 bar(g), the GSDH6 is designed to control back pressure in applications that combine high peak flow rates with high pressure ratings. Body material is typically stainless steel 316L dual certification alloy. Diaphragms and O-rings are available in PTFE, PEEK, Viton, and others to fit specific application temperature and media requirements.
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.
