Brief description of fluorine lined check valve manufacturer's electric valve control unit

check valve Manufacturer's description of electric valve control unit
The electric valve control unit consists of a main station controller and on-site electric valves connected to it. The main station controller controls multiple field control valves hanging on the circuit through a two-wire current loop (bus), which can be several kilometers long. Multiple electric valves are interconnected into a loop through only two buses, clamp type Fluorine-lined Butterfly Valve Only the starting and ending buses are connected to the main station controller at the end, and all valve information enters the main station controller through communication on both buses. Each field device has redundant communication channels in two directions, which improves the communication availability in case of line faults. The Pakscan field control module can be installed in RotorkIQ, IQT, AQ, Q, and A-series actuators, while the universal field control module can be connected to equipment from other manufacturers, such as pumps, solenoid valves, electric valves, etc.
The main station controller continuously collects information from the on-site control module to read the opening, torque, address, alarm and other data and status information of the intelligent valve, Fluorine lined DC globe valve Isolate on-site faulty equipment and communicate with DCS through standard protocols such as Modbus RTU to upload real-time data and equipment operating status, receive valve control commands, and achieve control of various intelligent valves and equipment on site. In order to increase reliability, a redundant main station controller is adopted, and the communication interface and lines with DCS are also redundantly configured. While controlling the communication method, PTFE lined valve Electric valves and other actuators can also use local control, hard wired remote control, and auxiliary inputs, greatly improving the reliability of control and the flexibility of configuration.
