The document describes a compact sampling valve type 616M that features a cast body with a conical piston seating hard faced with stellite for better tightness and longer lasting sealing. It has a back seat and piston tightness with an FEP encapsulated viton o-ring for low maintenance, easy cleaning, and low contamination risks. The valve allows for direct sampling in the process flow with a sampling pot that has a quick disconnector and polished internal and external surfaces.
