Abstract
A valve for connecting a fluid sampling device to a fluid source is provided that includes a body adapted to be secured to the fluid source and a valve member moveably disposed within the body. The body includes a coupling interface configured to sealingly mate with the sampling device. The valve member is actuated by the sampling device during attachment of the sampling device to the valve body. The sampling device actuated valve member is moveable between a first position in which a flow path between the fluid source and the sampling device is closed and a second position in which the flow path between the fluid source and the sampling device is open. When the fluid flow path is open, the sampling device can withdraw a fluid sample for inspection and return the fluid sample to the fluid source without exposing the fluid to the surrounding environment.
