Spot supply of original Yamatake smart valve positioners AVP series
The Yamatake AVP series intelligent valve positioners are the most common and high-performance electro-pneumatic intelligent valve positioners under the Japanese Azbil brand, and they have gained a certain level of user favor and recognition in the positioner market. The SVP3000 Alphaplus is an intelligent electric/pneumatic valve positioner based on microprocessor technology. It receives DC current signals from control devices and controls pneumatic valves. In addition to basic functions, the SVP3000 Alphaplus also features communication capabilities, automatic setting programs, and self-diagnostic functions, greatly enhancing productivity and efficiency. Calibration, setting, and self-diagnosis can be performed using HART communication devices. The Yamatake AVP series intelligent valve positioners mainly include the Yamatake AVP302 valve positioner, Yamatake AVP300 electric valve positioner, Yamatake AVP302-RSD3A valve positioner, Yamatake AVP102/AVP102H positioner, Yamatake AVP301-RSD3A/4A positioner, Yamatake AVP100 positioner, and Yamatake AVP100 electric valve positioner.

Here are the key features of the Yamatake (Azbil) AVP Series Smart Valve Positioners—particularly the AVP300, AVP301, and AVP302:
🎯 Core Functionality
Input Signal: 4–20 mA DC with split-range compatibility.
Output Pressure: Proportional pneumatic control for single or double-acting actuators.
Auto Setup: One-touch calibration for zero, span, and travel direction—ideal for field commissioning.
📈 Performance & Feedback
Valve Position Feedback:
AVP301: Built-in 4–20 mA valve travel transmitter.
AVP302: Includes digital feedback via HART protocol.
Positive Seating: Secure valve closure below a user-defined signal threshold to ensure tight shutoff.
🛠️ Diagnostics & Communication
AVP302:
HART communication for integration into asset management systems.
Valve diagnostics (stick-slip, travel histogram, cycle count, etc.).
Fail-Safe Modes: Configurable actions during signal loss or failure.
🧩 Installation & Flexibility
Compact Modular Design: Easy mounting, reduced footprint.
Wide Compatibility: Suitable for linear and rotary actuators.
Optional Reversing Relay: Allows control of double-acting actuators.
