Abstract

The valve system is used in transferring a reference gas from an aerosal container to a flexible enclosure temporarily installed around a gas detector to be tested, such as a carbon monoxide detector. The valve system comprises a first component 1 is a cap with a central orifice 4 that fits over a standard aerosal valve, the cap may have raised portions 8 thereon to penetrate a flexible enclosure such as the bag installed around the detector. A second component 2 is an annulus that locks onto the upper surface of the cap and in use the first and second components trap the flexible enclosure or bag and puncture it.
