Valve characteristic
Since the VQP/VQI is an On/Off PICV, the valve characteristic is not based on a modulating
function. The valve characteristic is made up of two operating points:
● The PICV is closed at stroke H/H
100
= 0 and volumetric flow V/V
100
= 0
● The PICV is open at stroke H/H
100
= 1 and volumetric flow V/V
100
= 1
