Abstract
A valve for obtaining a sample from a continuous flow of fluid includes a primary flow path for directing a continual flow of the fluid through the valve, a valve stem which engages a passage in a valve seat for metering a sample of fluid passing through the primary flow path out through a separate outlet passage in the valve. The valve further includes a passage separate from the primary flow path for injecting a purge gas into the sample outlet passage to remove any sample fluid contained in the outlet passage after the sample valve has been closed and before the sample container is taken off-line so as to avoid atmospheric emissions of the sample fluid.
