Azbil Valve Positioner
Azbil Valve Positioner 300 Series Model AVP302
OVERVIEW
Smart Valve Positioner 300 Series Models AVP300
are current-pneumatic smart valve positioners.
The 300 Series receives a DC current signal from control
devices and controls pneumatic valves. In addition to this
basic function, the 300 Series has communication capabili-
ties, automatic configuration program, and self diagnostics
functions that will greatly increase productivity and the
efficiency of plant operation.
The model AVP302 has a HART® communication protocol.

FEATURES
Easy to use
•
Auto setup
The auto-setup function is a fully-automatic configura-
tion program which specifies the actuator and adjusts the
zero and span of the valve. The program can be turned on
simply from an external switch so that adjustments to the
valve can be performed quickly and safely in hazardous
areas.
Valve diagnostic (Model AVP302 only)
Following parameters can be monitored by HART® com-
municator or Control Valve Maintenance Support System
Valstaff.
Stick Slip
Total Stroke

Shut-Off Count
Max. Travel Speed
High reliability
•
Positive seating
The positive seating function completely shuts off the
valve if the input signal becomes lower than previously set.
This in turn enhances the full shut-off capabilities of the
valves.
•
Self-diagnostic
The self-diagnostic function provides with the ability to
check the status of the positioner at any time and to alert
in case of failure.
Single model for multiple specifications
The 300 Series’ settings can be changed without replacing
any parts. A single model can be modified to suit any ap-
plication.
• Input range:
Configurable to any required range for split range
Flow characteristic:
Linear, EQ%, Quick opening or custom user characteris-
tics
• Actuator type:
Single or double acting actuator (optional reversing relay
required)
Travel transmission
The 300 Series receives a DC current signal from control
devices and controls pneumatic valves. In addition to this
basic function, the 300 Series has communication capabili-
ties, automatic configuration program, and self diagnostics
functions that will greatly increase productivity and the
efficiency of plant operation.
