Product Description
Yamatake AVP300 Smart Valve Positioner: Comprehensive Product Overview
Product Introduction
The Yamatake AVP300 is part of the 300 Series Smart Valve Positioner developed by Azbil Corporation (formerly Yamatake Corporation), a leader in industrial automation solutions. Designed for precise control of pneumatic valves, the AVP300 integrates advanced diagnostic and automation features to optimize industrial processes in sectors such as oil and gas, chemical processing, power generation, and water treatment
As a current-to-pneumatic smart positioner, the AVP300 converts a 4-20 mA DC input signal from control systems into precise pneumatic output, enabling accurate valve positioning. It supports both single-acting and double-acting actuators (with an optional reversing relay for double-acting configurations), making it versatile for diverse valve types and industrial applications

Key Product Features
Auto-Setup Function
The AVP300 features a fully automated configuration program that adjusts valve zero and span settings based on actuator specifications. This eliminates manual calibration, reduces setup time by up to 70%, and ensures consistent performance even in hazardous environments. The process is initiated via an external switch or software, enabling rapid deployment
Multi-Specification Adaptability
A single AVP300 unit can be configured for multiple applications without hardware modifications. Key adjustable parameters include:
Input Range: Split-range compatibility for customized control scenarios.
Flow Characteristics: Supports linear, equal percentage (EQ%), quick-opening, and user-defined curves.
Actuator Compatibility: Works with single- or double-acting actuators (requires a reversing relay for double-acting setups)
Positive Seating Function
Enhances safety by forcing the valve to fully close if the input signal drops below a predefined threshold. This feature is critical for applications requiring fail-safe shutoff, such as boiler feedwater systems or emergency isolation.
Robust Diagnostic Capabilities
While the AVP300 lacks built-in HART communication (available in the AVP302 model), it supports integration with Azbil's Control Valve Maintenance Support System "Valstaff" for monitoring parameters like valve travel and cycle count. This aids in predictive maintenance and reduces unplanned downtime
Durable Construction
Built with an aluminum housing (Ex d IIC T6 Gb certification), the AVP300 operates reliably in harsh environments, withstanding temperatures from -40°C to +80°C and air supply pressures of 140-700 kPa
Ease of Maintenance
The modular design separates the electrical and pneumatic circuits, allowing on-site maintenance without disassembling the entire unit. An integrated Auto/Manual switch simplifies operational checks (excludes double-acting actuators).

Product Advantages
Enhanced Operational Efficiency
The auto-setup function reduces commissioning time, while split-range configurability minimizes the need for multiple positioner models. This flexibility streamlines inventory management and lowers operational costs
Improved Safety and Reliability
The positive seating function ensures fail-safe valve closure, critical for preventing leaks in high-risk environments. Additionally, the rugged construction and wide temperature tolerance guarantee stable performance in extreme conditions
Reduced Maintenance Costs
Predictive diagnostics and modular maintenance capabilities extend valve lifespan and decrease downtime. The AVP300's self-diagnostic alerts enable proactive repairs before failures escalate.
Compatibility with Industry 4.0
While not natively equipped with HART, the AVP300 integrates seamlessly with Azbil's Field Communication Software (Model CFS100) for remote configuration and monitoring, aligning with smart factory initiatives.
Sustainability Benefits
Precision control minimizes energy waste in pneumatic systems, contributing to lower carbon footprints in industrial operations
