Tables to determine the dial setting for a desired volumetric flow.

Δpmin [kPa] based on volumetric flow; interpolate missing values.

NOTICE
Presetting tables indicate expected nominal volumetric flow

During commissioning, check whether current pre-settings correspond to planned design.

  1. Further adjustment of pre-settings may be required to achieve needed volumetric flow.

Presetting range non-linear - Using a linear interpolation will cause a minor offset.

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/H100 = 0 and volumetric flow V/V100 = 0
  • The PICV is open at stroke H/H100 = 1 and volumetric flow V/V100 = 1
