AB-PM DN 40 to 100 is the ideal solution for

applications where a so called staged installation,

hand over and commissioning is used. In such

cases, the 1

stage is installation of backbone

piping without terminal units. AB-PM is used as

DPCV with flow limitation, ensuring the specified

design pressure and flow to each zone. The 2

stage is then the installation of terminal units.

DPCV: several fancoils with

individual room control

Fig. 3 Staged commissioning – 2nd stage : Installation of terminal units

In the 2

stage of commissioning the installation

of terminal units can be done. Optionally the

AB-PM can be changed from differential pressure

controller to pressure independent control valve.

This allows flexibility when designing the zones.

If only one terminal unit is used in the zone, the

AB-PM as a PIBCV can be used to control that

unit and no additional valves are needed.

Typical applications are shopping malls and shell

& core office buildings.

The AB-PM ensures the required flow for each

zone and maintains hydronic balance in the

system.
