Actuation
HollySys APV400 Intelligent Valve Positioner
HART 7 intelligent positioner for linear and rotary pneumatic actuators with auto-tuning and valve diagnostics.
Product code: APV400
Brand: Hollysys
Product Overview
The HollySys APV400 controls valve position from a 4–20 mA signal and communicates through HART 7. It supports linear and rotary pneumatic actuators, intelligent auto-tuning, and adaptive predictive control to improve valve-loop response. Configuration and diagnostic functions assist commissioning, predictive maintenance, and valve-assembly condition assessment.
