The SSV Spot Sampling Valve maximizes natural gas spot sampling repeatability and accuracy while simplifying the sampling process. It fits between the sample probe and sample cylinder and includes the liquids separator, bypass vent valve, fill & empty valve, and extension tube pigtail with flow regulating port - recommended by the GPA 2166 standards for best accuracy. Field testing has proven that using the SSV with heated sample bottles provides consistent accurate samples. It can be used with the helium-pop or fill & empty sampling methods.
