* Resolution and repeatability figures reflect a
positioner that is adjusted with a minimum dead-
band to reduce bleed gas. If the deadband is
eliminated (slightly increasing the bleed gas),
resolution and repeatability will improve.

Accessories

•
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.
•
NBV No Bleed valve – same function as
DPS, no adjustments or tubing required.
Works up to 150 psig power gas.
•
DPS Series Non-Bleed Sensor: achieves
non-bleeding conditions in either full open
or full closed positions. Selection based
upon power gas pressure and discharge
gas pressure.
