A hydronic control valve assembly connects the main supply and return headers to a heating or cooling zone. The supply branch includes a strainer, two typical zone isolation ball valves, an autoflow balancing valve, and a modulating control valve. The piping routes conditioned fluid from the hydronic supply to the zone and returns it through the hydronic return loop.
