Bypass pipes, accompanied by a three-way control valve, are often seen in hydronic systems at both served loads (e.g., reheat coils) as well as at primary equipment (e.g., cooling towers). Reasons for ...

The ultimate goal of every heating and cooling installation is to provide the desired indoor climate at the lowest possible energy cost. Today’s advanced control technology means that, in theory, ...

FLOWCAL AUTOMATIC FLOW BALANCING VALVES provide the precise control critical for balancing hydronic circuits. The newly-designed valves are constructed of low-lead brass. They automatically control ...

Flow is controlled by either throttling or diverting it. Throttling involves reducing orifice size until all of the flow cannot pass through the orifice; bypassing involves routing part of the flow ...
