Over the past 20 years, I have been very active on the construction side of the business more than the design side. I have been frequently involved in the testing, adjusting, and balancing of air and water systems. These projects varied from D-B to troubleshooting to solution implementation. At this point in my career, I would say my construction and practitioner approach to the building industry has complemented what I had learned in my first 20 years working in the consulting business.
In the past, when design engineers were providing chilled water and hot water constant flow systems, these balancing valves were needed at terminal unit coils to assist in maintaining a constant design flow to a coil or around that coil if the unit had a three-way control valve.
