•
Atmospheric Bleed Control (
AB Control
)
:
maintains minimum pressure differential
across the cylinder. The AB Control is re-
quired in order to provide the necessary
output to operate the control valve under all
design conditions.
•
Quick Exhaust Valve
: purges high volumes
of gas from the actuator when there is a
need for an unusually quick response.

Performance figures for resolution and repeatability reflect those of
a positioner adjusted with a minimum deadband for reduction of
bleed gas. If the deadband is eliminated, bleed gas will increase
slightly and resolution and repeatability will improve.
