Original High Quality Azbil Smart Valve Positioner 300 Series Model AVP300 AVP301 AVP302 Valve Controller

The Azbil Smart Valve Positioner 300 Series (Models AVP300, AVP301, AVP302) is a current-pneumatic intelligent device designed to receive 4-20 mA DC signals from controllers and precisely position pneumatic valves. It enhances plant efficiency with communication, auto configuration, and self-diagnostics. The AVP301 includes valve travel transmission for remote monitoring via 4-20 mA output, while the AVP302 supports HART protocol for advanced diagnostics like stick slip and cycle count. Suitable for single or double-acting actuators (with reversing relay for double), it offers linear or custom flow characteristics and is ideal for hazardous areas with various certifications.

• Auto Setup: Fully automatic configuration for actuator specification and zero/span adjustment, activated via external switch for safe hazardous area use.
• Versatile Configuration: Single model handles split-range input, linear/EQ%/quick opening/custom characteristics, and single/double-acting actuators.
• Valve Diagnostics (AVP302): Monitors stick slip, total stroke, travel histogram, cycle count, shut-off count, max travel speed via HART or Valstaff software.
• Positive Seating: Ensures complete valve shut-off below a set input signal threshold for enhanced sealing.
• Easy Maintenance: Separate electrical and air circuits; built-in Auto/Manual switch (single-acting only) for on-site valve checks.
• Travel Transmission (AVP301): Outputs 4-20 mA proportional to valve travel for control room monitoring.
• Double-Acting Compatibility: Adds reversing relay for output air pressure control.

Ideal for process control in industries like oil & gas, chemicals, pharmaceuticals, and water treatment. Used with pneumatic actuators on linear/rotary valves for throttling or on-off services. Supports hazardous areas with flameproof/intrinsically safe approvals, enhancing valve performance in safety-critical systems.

1. How does auto setup work? Activate via external switch; it automatically configures actuator type and adjusts zero/span without tools.
2. What is positive seating? Shuts off valve when input signal drops below a preset value for tight sealing.
3. Can it handle double-acting actuators? Yes, with optional reversing relay added to output air connector.
4. What diagnostics are available on AVP302? Stick slip, total stroke, histogram, cycle/shut-off count, max speed via HART/Valstaff.
5. How to monitor valve travel remotely? AVP301 outputs 4-20 mA proportional to travel; AVP302 uses HART.
