High-pressure Azbil Actuators Control Valves Smart Valve Positioner AVP700 AVP701 AVP702 AVP703

The Azbil AVP700 Series comprises advanced electro-pneumatic valve positioners designed for precise and reliable control of linear and rotary actuators in industrial control valves. Whether it is the AVP701/AVP702 with HART communication or the AVP703 for FOUNDATION Fieldbus, these positioners provide flexible protocol support, built-in diagnostics, and robust construction to meet demanding requirements in oil & gas, chemical, power, and general process industries.

With features such as automatic calibration, valve signature diagnostics, pressure monitoring, and compatibility with a wide range of actuators and valve types, the AVP700 Series makes valve automation easier, smarter, and more reliable.

• Multi-protocol support: HART (AVP701 / AVP702) or FOUNDATION Fieldbus H1 (AVP703)
• Support for both linear and rotary actuators (single or double acting) with standard NAMUR / IEC mounting
• Built-in pressure sensors for output and supply monitoring, enabling valve health diagnostics
• Automatic setup and calibration for quick commissioning
• Valve signature analysis and step response test for predictive maintenance
• Configurable output characteristics: linear, equal percentage, quick opening, or custom 21-segment curve
• Local user interface with display and buttons; suitable for safe area or explosion-proof environments (where certified)
• Wide ambient temperature range, robust enclosure, and industrial-grade durability

General Specs:

• Stem travel range (linear): 14.3 – 100 mm (lever angle ±4° – ±20°)
• Output stroke/torque: per actuator spec and supply pressure
• Ambient temperature: -40°C to +80°C (varies by variant)
• Materials and enclosure: industrial-grade housing, corrosion-resistant internals
• Mounting: NAMUR / IEC or VDI/VDE standards for rotary actuators

• Oil and gas processing, refining and petrochemical plants — control valves for critical flows and pressure regulation
• Power generation — steam, feedwater, and boiler control valves
• Chemical plants — valves with corrosive or hazardous media requiring robust instrumentation
• Water and wastewater treatment plants — flow and level control valves requiring reliable actuation
• Pulp & paper, food & beverage, and other industrial process lines needing precise control and diagnostics
• Hazardous or explosive areas when explosion-proof variant is selected

Q1: What is the main difference between AVP701, AVP702, and AVP703?
A1: AVP701 and AVP702 both use HART communication, with AVP701 offering feedback (position feedback) support. AVP703 uses FOUNDATION Fieldbus H1 digital protocol, suitable for integrated fieldbus networks.

Q2: Can the AVP700 Series support both linear and rotary actuators?
A2: Yes. They support linear actuators per NAMUR/IEC standards and rotary actuators per VDI/VDE mounting standards.

Q3: Does the positioner offer diagnostics and preventive maintenance features?
A3: Yes. Built-in pressure sensors, valve signature analysis, step response testing, and supply/output pressure monitoring support predictive maintenance.

Q4: Is there support for explosion-proof installations?
A4: Yes. Explosion-proof and hazardous area certified variants are available (check certification per region and model).

Q5: What output characteristics can be configured?
A5: The output characteristic can be set to linear, equal percentage, quick opening, or a custom 21-segment curve depending on process requirements.
