TUBING CONNECTIONS
Type AV positioners are available with (Type AV___1___ and
AV___2___) or without (AV___0___) manifolds. The following out-
lines supply air information and describes the piping connections.
Air Supply Pressure
The air supply pressure range is 172 to1034 kilopascals (25 to
150 pounds per square inch gage).
NOTE: The minimum supply pressure should be 34.4 kilopas-
cals (5 pounds per square inch gage) above the operating pres-
sure required by the actuator.
Air Supply Filtering
An external filter is recommended for Type AV positioners for pri-
mary filtration of the supply air. ABB provides supply air filters as
accessories. Refer to Table 1-12 for part numbers.
NOTE: Primary air supply filters are recommended for position-
ers with a manifold (AV___1/2___), without a manifold
(AV___0___) or with a gage block (AV___3___).
