CONCOA 485 Series | High Flow Source Regulator | 3000 PSIG Inlet, Brass, Cleanroom Assembled
The CONCOA 485 Series is a compact brass regulator for primary source pressure control in high flow inert gas systems, for example bulk distribution, high purity chamber pressurisation and liquefied hydrocarbon analysis. It can be rear panel mounted on a bracket or connected straight to the gas source by flexible hose, and internal pressure equalisation steadies delivery pressure as flow changes.
There is no single part number: the series is configured to order, and outlet range, gauges, connections and options are selected at that stage.
- Balanced stem seat for steady delivery pressure at high flows
- Cleanroom assembly avoids contamination at installation
- Rear panel mount with exhaust gas venting
- 1/4 in FNPT ports for gauges, relief valve and auxiliary inlet
- Cv 1.0 and 3000 PSIG (210 BAR) bare-body inlet rating
