1、 Overview of Intelligent Valve Position Feedback Regulator
The TX-XMT series intelligent valve position feedback regulator is a new generation of intelligent automatic regulating instrument developed by integrating multiple new technologies. It can be widely used in industries such as petrochemicals, heat exchange, heating, water supply, metallurgy, and food. When combined with electric regulating valves, it can accurately control process parameters such as temperature, pressure, liquid level, and flow rate.
2、 Characteristics of intelligent valve position feedback regulator
1. Automatic/manual disturbance free switching, can be forced manually, convenient for debugging
2. The dead zone of the valve position can be set for control, effectively eliminating the phenomenon of valve jamming
3. Relay forward and reverse direct output, eliminating the need for servo amplifiers
