This isometric piping detail connects main chilled water and heating water lines to a radiant zone using four typical zone isolation ball valves, two typical strainers, a two-position mixing valve, two typical modulating control valves, and two typical autoflow balancing valves. The assembly ties into main chilled water supply and return lines alongside heating water supply and return lines, utilizing the larger of the heating water return or chilled water return insulation. Supply and return lines feed out to the zone while maintaining proper valve sequencing and balancing equipment.
