Data sheet AB-PM DN 40-100

Mounting AB-PM DN 40-100 should be mounted in the

return pipe. The arrow on the valve body should correspond with the flow direction of the medium. The impulse tube should be connected to the supply pipe using the included ¼”-/” adaptor (003L8151).

Alternatively, the impulse tube can be connected to a partner valve, such as ASV-BD or MSV-F2 1). Using a partner valve offers additional service/ troubleshooting functions such as flow verification, shut-off etc.

If the impulse tube is connected to the supply pipe the AB-PM functions as a differential pressure controller with flow limitation. The impulse tube can also be connected to the return pipe (upstream from the AB-PM) or to the red test plug with adapter 003Z0691. In that case the AB-PM will function as a pressure independent control valve with 100% authority.

Commissioning

Service and trouble shooting

When filling the system make sure to open the supply valve before opening the return valve. The pressure on the upper side of the membrane (impulse tube) should always be higher than the pressure on the lower side of the membrane (at the valve)

Flush the impulse tube and ensure the HVAC system is de-aired before starting the system.

For the setting procedure please refer to the operating instructions enclosed with the product.

It is recommended that an FV filter be installed in the system supply pipe.

The valve can be manually shut off for service purposes, up to 16 Bar.

AB-PM is equipped with 3 test plugs for flow verification, service and trouble shooting.

Alternative

Fig. 1 AB-PM can be connected to flow or return with

impulse tube

Please check the following if the valve does not function correctly:

1. Is the flow direction through the valve correct?

2. Is the impulse tube fitted correctly and are any test plugs open?

3. Is the valve shut-off open? (see operating instructions)

4. Is the available pressure big enough?

AB-PM DN 40 to 100 is the ideal solution for applications where a so called staged installation,

Typical applications are shopping malls and shell

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

PIBCV: zone control for

one terminal unit

In the 2nd 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.
