VALVE ASSEMBLY AND SYSTEM |
摘要 |
A valve assembly and system designed to enable an operator to withdraw a sample of a liquid from a source, typically for collection in a collection vessel. The valve assembly includes a valve housing, a sleeve secured to the valve housing and having an inner surface being at least partially threaded for mating with a threaded section disposed on the valve stem body. The valve stem has an internal longitudinal bore, a sealing boot, circumferential seals, and openings to the bore, and is movable between an open position (wherein the fluid flows from the source through the valve assembly) and a closed position (wherein the valve stem prevents the fluid from flowing from the source into the valve assembly). |
