Detailed introduction
Shanwu valve positioner AVP301-RSD3A is an electro-pneumatic intelligent valve positioner that can receive DC current signals from control devices and control pneumatic valves.
Here are the key features of the Shanwu (Azbil) AVP301 Smart Valve Positioner:
Valve Travel Transmitter: Outputs a 4–20 mA signal proportional to valve position, enabling remote monitoring from the control room.
Auto Setup Function: Fully automatic configuration that adjusts actuator zero and span with a simple external switch—ideal for hazardous areas.
Single Model, Multiple Specs: One unit can be configured for different input ranges, flow characteristics (linear, EQ%, quick opening, or custom), and actuator types (single or double-acting with optional reversing relay).
Positive Seating: Ensures full valve shut-off when the input signal drops below a set threshold.
Easy Maintenance: Separate electrical and air circuits simplify on-site servicing. Includes an Auto/Manual switch for quick operational checks (not available for double-acting actuators).
Compact and Multifunctional: Designed for high performance in a small footprint, with wide applicability across industrial settings.
