The shift to electric PRVs is a result ofthe overall trend of digitally connecting all components to building automation systems for greater visibility and control and for lower energy consumption.
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).
These six case studies, covering just the last three years, illustrate how bad second-order effects can get when there are problems with the bypass pipe’s balancing valve.
Watts has introduced the LF iDROSET CSD, a lead-free static balancing valve solution for use in potable hot water systems and recirculation loops. The LF iDROSET’s dial provides a way to view flow rate directly on the valve and make tool-free adjustments as needed.
