ABSTRACT:
The improved sampling valve assembly includes a diverting valve and an optional isolation valve in series for providing redundant shutoff. The assembly includes rounded-end, side-ported needles (as part of an easily-replaced needle assembly) to pierce the receptacle septum without "coring" and help prevent liquid "carryover." The assembly also has features providing metered, low pressure flow into the receptacle and very low dead volume. A receptacle guide has an interior cavity shaped like the receptacle to guide the inserted receptacle for aligned engagement of the septum with the needle assembly. The needle assembly is removable by removing only the keeper nut.
