Azbil AVP300 Smart Valve Positioners include AVP300, AVP301, and AVP302. The AVP301 model also has a valve travel transmitter function, while the AVP302 supports the HART protocol. This series of products has a sophisticated design and low maintenance cost, making it an ideal choice for various industrial process control.
Features of Azbil AVP300 Smart Valve Positioner
1. Easy to Use
The auto-setup function simplifies valve adjustments by automatically configuring the actuator and zero/span settings, making it safe and efficient, especially in hazardous areas.
The AVP300 positioner is a versatile positioner with flexible configuration options, accommodating various input ranges, flow characteristics, and actuator types without requiring hardware changes.
2. Positive Seating
The positive seating function ensures a complete valve closure when the input signal drops below a set point.
3. Easy maintenance
The positioner’s modular design simplifies maintenance by separating the electrical and pneumatic components. Additionally, the standard Auto/Manual switch facilitates easy operation and troubleshooting.
4. Mounted on either a single or double-acting actuator
Compatible with both single and double-acting actuators, with a reversing relay required for double-acting models.
5. Improves process control
High accuracy allows tighter process control and a reduction in product variability
6. Improves Productivity
Easy-to-use fully automatic set-up and calibration, with diagnosis, makes these tasks easier and able to be completed in less time
