In fact, during the use of the pneumatic control valve, various failures may occur, but if you solve the problem carefully, it will not affect its use. Even a simple solution is far better than no treatment. Related information about the electric control valve (I) The installation guide of the electric control valve is worth seeing if you understand the working principle of the pneumatic control valve, which causes the pneumatic butterfly valve to not close tightly. What are the different reasons for the different sealing properties of the pneumatic butterfly valve

How does it work? It is believed that some laymen are curious about its working principle. Let's briefly explain: through the positioner, solenoid valve or other equipment, the gas can be effectively controlled, so that the dry and lubricating gas can be input into the cylinder block, and the pneumatic device will rotate according to the relevant requirements, so that the start, close and adjustment of the butterfly valve can be realized. If you want to monitor the pneumatic butterfly valve in real time, you can use an intelligent positioner to connect with the field bus, and then you can monitor and diagnose the status of the butterfly valve.
