How to connect the air way of gas-liquid supercharging cylinder?

Now, with the development of automation technology, more and more factories need to use the pressurized cylinder, so when many factories buy the pressurized cylinder back to use, they will encounter a lot of problems in the gas connection. The connection error will lead to the abnormal operation of the pressurized cylinder, and serious damage will be caused to the pressurized cylinder. So today I will represent Suzhou billion like Linde to explain to you the connection method of pressurized cylinder. First of all, before we buy a new pressurized cylinder, we also need to prepare a very important part is the solenoid valve, which is used to control the direction of the pressurized cylinder air source, flow rate, speed and other parameters of the basic automation components.
