ITT Conoflow GH30 Back Pressure Regulator

The ITT Conoflow GH30 Back Pressure Regulator is used to maintain a constant upstream pressure of gas, vapor or liquid. Designed for accurate regulation under low flow conditions, this model back pressure regulator is widely used for protection of analysis instrumentation, or as a relief valve in supply pressure lines to control devices. The GH30 back pressure regulator is available in a brass and aluminum combination, or all stainless steel construction. This model has a Buna-N diaphragm assembly as standard, and a Teflon / Buna -N / Teflon diaphragm assembly is used in the stainless steel models for corrosive services. Regulated pressure ranges for this back pressure regulator are 0-3 psi, 5 psi, 15 psi, 25 psi, 35 psi, 50 psi, and 125 psi (0-21 kPa, 35 kPa, 103 kPa, 241 kPa, 345 kPa, and 862 kPa).

A back pressure regulator holds pressure on its inlet side, relieving downstream only as needed – the mirror image of a pressure-reducing regulator. The GH30’s sensitivity under low flow makes it a precise, compact alternative to a relief valve for analyzer sample systems and instrument supply lines.
