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. 

Input Signal: 

Standard:

 

           3-15 psi or 6-30 psi. 

Adjustable:   

Zero is adjustable from 2-

30 psig, span is adjustable from 5-24 

Output Signal: 

Pneumatic pressure as required by the 
actuator up to full supply pressure. 

Loss of Signal: 

Reverse Acting: 

Open on loss of signal. 

Direct Acting: 

Close on loss of signal.

* 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.
