Abstract
A sampling valve assembly for use in sampling fluid streams under hazardous conditions. The assembly is adapted to be attached to a conduit of a process stream to cause a sample of the stream to pass through the assembly. The assembly includes a restricted axial passageway and gallery area for controlling the sample stream to provide a clean, representative sample at manageable conditions of pressure, velocity and turbulance where the sample of the sample stream may be taken. The sample exit port includes a conduit intended for eliminating dripping of sample material from the conduit.
