2. when matched to a cooling coil will not provide a linear relationship between
valve position and coil output. This can lead to poor coil performance and low
delta T syndrome. The solution is to try and keep the valve authority above
0.5. In other words, the pressure drop though the control valve when it is fully
3. open should be at least 50% of the pressure drop from the supply to return
line.
