Can a solenoid valve replace a pneumatic on/off valve?
Thread Content
I would like to ask everyone: we currently use DN20 pneumatic switch ball valves to cut off the compressed air pipelines. Can an electromagnetic valve be used as a replacement for these switch ball valves?

It should be possible to do it; the situation with the locator isn’t favorable, so another option needs to be chosen
Hello, I’m not very familiar with solenoid valves. Could you tell me what the advantages and disadvantages are of using a solenoid valve in place of a pneumatic ball valve here (where there is also a solenoid valve to control the cylinder)?

Also, do solenoid valves have positioners as well? Isn’t it only regulating valves that are suitable?

Theoretically, it is possible. If it is just an air pipeline without any explosive gas components, then a DN20 solenoid valve is sufficient; in such cases, a direct-acting solenoid valve can be used. It is necessary to take into account the power consumption of the solenoid valve, as well as various aspects of the entire power supply circuit, including the capacity of the output contacts, the capacity of the relay, and the specifications of the cables. . . Moreover, solenoid valves with larger sizes tend to have a higher failure rate. In environments where explosive gas components are present, pneumatic systems provide explosion protection, while intrinsically safe designs make it easier to achieve this goal; even operating larger-sized valves is much simpler in such cases
What is the air pressure? If explosion protection is not a concern, then it’s just the cost. Additionally, pneumatic ball valves are two-way switches, while solenoid valves have a direction. From just a pipeline perspective, there shouldn’t be anything else
