BOA-Control/ BOA‑Control IMS
6.3 BOA-Control/BOA-Control IMS
Non-compliance with the following installation instructions may result in failure of
the measuring function!
CAUTION
Welding work in the area of the pipe flanges
Thermal damage to valve disc and sensors!
▷
Remove the valve before carrying out welding work.
CAUTION
Installation in copper pipes
Damage to the electrostatic plastic coating!
▷
Fit fabric-reinforced rubber gaskets (sealing elements to DIN EN 1514) between
the valve flanges and the pipe flanges.
▷
Fit insulating bushes with centring collar made of polyamide between bolts and
bolt holes.
CAUTION
Flow in opposite direction of flow direction arrow
Measuring impossible!
▷
To enable measurement, the flow direction through BOA-Control/BOA-
Control IMS valves must correspond to the flow direction arrow.
For the shut-off function, an alternating direction of flow is permitted for BOA-
Control/BOA-Control IMS valves up to DN 200.
Valves from DN 250 can only be used for shut-off duties up to the differential
pressures indicated below, even when handwheel levers are used!
