This isometric mechanical piping detail shows a hydronic control valve assembly connecting the main supply and return lines to a building zone. The supply branch incorporates a strainer followed by two typical zone isolation ball valves and an autoflow balancing valve. A modulating control valve regulates flow within the loop before returning to the main hydronic return line.
