Yokogawa GCRV-GBARS88N0151/A036/B036

The GCRV-GBARS88N0151/A036/B036 is a pneumatic rotary sample valve dedicated for Yokogawa GC1000 Mark II process gas chromatograph. As the core flow path switching component of the GCRV series, GBARS88N0151 defines the valve type, port configuration and interface specification, while the suffix A036/B036 indicates gas connection dimensions and hardware revision. It executes automatic flow switching between sample gas, carrier gas and chromatographic columns to realize timed injection, column switching and backflushing functions in online chromatographic analysis cycles.

This rotary valve adopts high-precision pneumatic actuation with high switching repeatability. Its wetted seals and flow path are designed for industrial process gas conditions, supporting high-temperature heat tracing installation and corrosion-resistant performance for petrochemical and chemical sample media. It runs automatic periodic switching under the control logic of the GC1000 host, with no electrical contact parts, making it suitable for explosion-proof industrial field environments.

The GCRV-GBARS88N0151/A036/B036 is widely applied in online process gas chromatography loops of petrochemical plants, refineries, natural gas stations and chemical facilities for continuous component concentration monitoring. This dedicated GC spare part has entered the later stage of its product lifecycle. Most available units are original new or fully tested qualified spare parts for chromatograph overhaul and emergency valve replacement. Port count, interface size and heat tracing parameters must be verified before replacement to ensure compatibility with existing chromatographic flow paths.
