Product Advantage

1. Intelligent control: Intelligent Regulating valve system can be controlled under control valve to receive 4-20mA signal, regulating valve opening can also be used as a stand-alone controller or transmitter to work independently, it receives 4-20mA analog signals as a controller.
2. Communication intelligence: it can be connected with the main control room and digital communication. The addressable digital signal sent by the main control room is received by the valve, the main computer can regulate and manage the regulating valve group, it can connect the network with other methods, connected separately or multi valves.
3. Diagnostic Intelligence: Install the Intelligent Control valve system in the field, more quickly than the centralized controlling mode of the instrument control room more accurate and safety.
4. Intelligent protection: on the one hand to protect the valve itself, on the one hand to protect the entire system.
