November 2007
Heating/Piping/Air Conditioning Engineering;Nov2007, Vol. 79 Issue 11, p38
The article deals with the utility energy-service contract at Eglin Air Force Base in Northwest Florida. A pressure-independent characterized control valve provides consistent flow over its entire operating range by automatically absorbing excess pressure so that its internal control valve always sees a constant pressure drop. The project shows how significant pressure-independent technology can be in the greater scheme of performance-contracting projects.
