The difference between the control valve and the general manual valve is that it cannot be regarded as an isolated element, but it is necessary to consider it as a part of the entire automatic control system. Many problems in the application of the control valve are not the problem of model selection and equipment, but the lack of understanding of the control valve by the user leads to the failure of the control valve to debug and cooperate with the control system. It is only necessary to recognize the key point of the problem, correctly select the valve, and properly debug the control valve in the system commissioning stage, which will greatly reduce the failure rate and make the automatic control system operate stably for a long time.

In order to ensure that the assembly position of the pneumatic pipeline ball valve and the pipeline position are in the same straight line, the two flanges above the pipeline need to be kept parallel, so as to ensure that the pipeline can bear the weight of the pneumatic pipeline valve itself. If it is found that the pipeline cannot bear the weight of the pneumatic pipeline valve, it is necessary to additionally assemble the support matching the front pipeline, The connection part between the electric ball valve and the flange valve needs to be equipped with the corresponding sealing gasket in strict accordance with the pipeline design. The bolts on the flange need to be symmetrical, and all the bolts need to be tightened one by one. When tightening the bolts, the force needs to be uniform, not too large or too small.
