Azbil Valve Positioner
Azbil Valve Positioner 200 Series Model AVP201
Features
Anti-vibration characteristics 10G, 2000Hz
Vibration resistance is improving so that it is five
times more durable than conventional current-pneumatic
positioners.
It is suitable for valves that are located in an environment
with strong vibration, which previously could use only
pneumatic positioners.
Easy to use
Auto setup
The auto-setup function is a fully-automatic configuration 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.
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 200 Series’ settings can be changed without replacing
any parts. A single model can be modified to suit any ap-
plication.

Configurable to any required range for split range
Flow characteristic:
Linear, EQ%, Quick opening or custom user characteristics

Travel transmission
The model AVP201 transmits a 4–20 mA signal proportional
to the valve travel. The valve travel can be monitored from
the control room.
