This analytical series of high-purity brass, single-stage regulators is recommended for non-corrosive analytical and process applications where precise pressure control is not required. This series is ideally suited for chromatographic carrier gas applications including FID, TCD, ECD, HID, and non-corrosive gas mixtures for analytical instrumentation. Machined from brass bar stock, this regulator body has minimal internal volume – there are no large cavities and pockets associated with forged-body regulators. These models feature dual filters to protect the valve seat from contamination, extending regulator service life while also reducing velocity of gas when opening high-pressure cylinder valves. An automatic reseating relief valve protects regulator components from over pressurization. Nickel-plating makes sure it looks good through many years of service.
