Balancing Valve

User's complaints about unbalanced hot or cold in different parts of the building are avoided. 
system design and installation error are easily corrected. 
Once completed a system hardly ever works exactly the way it was desired. 
Methods of calculation of pressure drop and flow rates are often inaccurate or inaccurately applied. 
System components like boilers/chillers, circulation pumps, valves etc. do not have to be oversized for possible errors and varying conditions" Just to be on the safe side". 
A balanced system not needing such "reserves" only needs the actually required flows usually less than a system which is not balanced and can thus save heating/cooling energy. 
The balancing valve often replace system components selected for system design, by other brands or types, which may have different characteristics. The entire system design may thus become more or less inaccurate.
