Valve group controllerIt is a device used in conjunction with valve electric actuators to control the opening and closing of electric valves, playing a key role in industrial automation systems. The following introduces its functions, applications, selection, and maintenance from several aspects:

Function:

1. Implementing automation control: When used in conjunction with automation control systems, it can efficiently achieve automation control and increase the stability and accuracy of valve control.

2. Control flow rate: Based on the set parameters and feedback signals, control the flow rate of the medium to achieve flow control and regulation.

3. Protecting other equipment: When the pipeline pressure exceeds the set value, the valve controller can protect the pipeline system by automatically closing the valve and reducing the flow rate.

　　Valve group controllerDaily maintenance items:

1. Inspect the casing: Check for cracks, deformations, or corrosion to ensure that the casing is intact and undamaged. Confirm whether the cable and pipeline connections are firm, without looseness or leakage.

2. Conduct a thorough environmental inspection:

Temperature and humidity: Ensure that the working environment temperature and humidity of the controller are within the specified range, avoiding overheating or excessive humidity.

Cleanliness: Check for dust and debris accumulation around the controller to maintain a clean environment.

3. Functional testing:

Simulated operation testing: Regularly conduct simulated operation testing to check whether the opening and closing of valves are flexible and accurate.

Parameter calibration: Calibrate the parameters of the controller as needed to ensure control accuracy.

4. Regular cleaning: Use a clean soft cloth or brush to remove dust and dirt from the surface of the controller, and avoid using corrosive cleaning agents.
