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 ...

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 ...

In August’s column, I discussed three-way control valves, their associated bypass pipes, and the importance of a balancing valve being located within the bypass pipe. Such balancing valves are needed ...

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 ...

Many of you have responded to recent water balance articles with this question: “What do we do when a water system lacks balancing valves and test ports?" Let’s take a look at how you can test, ...
