Is the solenoid valve a standard part? Mainly refers to the appearance size

It is not a standard part. The appearance and size of each manufacturer are different, but the relevant parameters are the same, such as the air source interface. The size, electrical interface size, and connection specifications are all the same, which means they are replaceable, as long as the technical parameters are consistent.
