One can easily see from Figure 1 that the control valve is the key link between the temperature of the building and the operation of the hydronic system. Unfortunately, valves are sometimes sized in the vacuum of a design basis. The manners in which the valve must interact with other equipment, maintenance needs, demand surges, and future expansion possibilities are often overlooked.
These are just some of the factors which cannot be overlooked, says Anthony McGuire of McGuire Engineers (Chicago). It is his belief that conscientious designers should think years ahead for the industrial building (and the process systems) they are designing.
