An isometric piping detail connecting primary chilled water supply and return lines alongside heating water supply and return lines to zone distribution piping. The layout incorporates four typical zone isolation ball valves, two strainers, a three-way diverting control valve, two modulating control valves, and two autoflow balancing valves. Pipe insulation is specified to use the larger of the heating water return or chilled water return insulation sizes. The assembly manages fluid routing and flow rates between the main risers and the thermal zone.
