KINKO KK500 smart valve positioner offers LCD display, 4-20mA input and IP66 protection with -40~60℃ operating range, featuring fuzzy PID control and non-invasive magnetic buttons for precise valve opening adjustment.
Product Overview
Equipped with a liquid crystal screen (LCD) that supports Chinese display.
Adopting a noninvasive magnetic induction button design.
The high-performance display screen supports operation at temperatures as low as -40 degrees Celsius.
Built-in air discharge tube for stronger lightning protection performance.
Accurate control can be directly achieved for small volume actuators, and automatic tuning and control can be performed for eccentric valves without the need for manual parameter setting.
Adopting an electrical conversion mechanism with strong seismic performance.
The high-performance nozzle baffle design has low requirements for gas source, low gas consumption, and good economy.
