Core Pipe Assemblies are a convenient way to clean up the flow through a piping system. They allow close mounting of the valve to the core to eliminate flanges, dead spots and heat losses.  The valves can  be welded to the core in parallel to the flow, perpendicular to the flow or tangent to the flow depending on the desired effect. Core pipe assemblies are most often used for vent and drain service, or in the smaller port sizes they are excellent for injecting solvents, colorants or additives.
