AVP307 Electro Pneumatic Valve Positioner AVP307-RSD3A Control Valve

OVERVIEW
Model AVP307, which is a normal current-pneumatic smart valve positioner equipped with a microprocessor,isavailable for the DC 4 to 20 mA instrumentation now inuse and compatible with HART communication and travetransmission output. This normal current-pneumatic positioner provides signifcantly greater usability than previous models, and covers a wide range of valve specifcations with a single model. Furthermore, by using this product to enhance the controllability ofthe control valve and monitor the operation of thcontrol valve,maximum cost-effectiveness will be ensured.
FEATURES
1.Easy adjustment (Adjustments can beeasilymade using only one screwdriver.)
Auto setup
This product recognizes the specifications ofthe mounted actuator, and automatically makes the appropriate settingsand optimal adjustments.
Easy zero/span adjustment
No mutual interference occurs in the zero/span adjustment process, lhe zero pointand span point remain unchanged even if other settings are changed.
2.A single mode covers awide range of specifcations.
With previous models, various specifcations were covered by replacing parts. With this model, various specifcations can be covered by changing the setting data.
Example: Configurable specifications
Input range (split-range)
Fow characteristic (linear, EQ%, Quick opening, userdefned custom value)
Travel transmission signaling system (analog)
3.Valve diagnostic
Following parameters can be monitored by HART com-municator or Control Valwe Maintenance Support System "PLUG-IN Valstaf".
Stick slip
Total Stroke
Travel Histogram
Cycle Count
Shut-Off Count
Max. Travel Speed

4.Forced valve shut-off feature

The user can set anyinput signal value as the low threshold that triggers walve shut-off.
5.Easy maintenance

The electrical circuit section and air circuit section are completely separate, making the maintenance of the aircircuit 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 thedouble-acting actuator.)
6.Travel transmission
The model AVP307 transmits a 4-20 mA signal proportional to the valve travel, The valve travel can be monitored fromthe control room.(in this case, 4-core cable is required for power supply circuit)
7.This product can be mounted in both single-acting and double-acting types of actuators.
To mount this product in a double-acting actuator, add areversing relay to the output air pressure connector.
