OVERVIEW
Smart Valve Positioner 300 Series Models AVP300/AVP301/AVP302 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 capabilities, automatic configuration program, and self diagnostics functions that will greatly increase productivity and the efficiency of plant operation.
The model AVP301 has a valve travel transmitter function which transmits a 4–20 mA DC signal. The model AVP302 has a HART communication protocol.
FEATURES
1. 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.
2. 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 application.
Input range
Configurable to any required range for split range
Flow characteristic
Linear, EQ%, Quick opening or custom user characteristics
Actuator type
Single or double acting actuator (optional reversing relay required)
3. Valve diagnostic (Model AVP302 only)
Following parameters can be monitored by HART communicator or Control Valve Maintenance Support System “Valstaff ”.
Stick Slip
Total Stroke
Travel Histogram
Cycle Count
Shut-Off Count
Max. Travel Speed
4. 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.
5. Easy maintenance
The electrical circuit section and air circuit section are completely separate, making the maintenance of the air circuit section at the work site easy. An Auto/Manual switch is standard equipment, so it is also easy to check the operation of the valve. (However, it is not available for the double-acting actuator.)
6. Travel transmission
The model AVP301 transmits a 4-20 mA signal proportional to the valve travel. The valve travel can be monitored from the control room.
7. Can be mounted on either a single or double-acting actuator.
On a double-acting actuator, a reversing relay is added at the output air pressure connector.
