Can the air passage part of the solenoid valve be used interchangeably?

1, the valve body structure is the same, depending on whether the sealing materials of the solenoid valve are the same, as long as the applicable medium temperature and pressure resistance of the two sealing materials are the same, they can be interchanged. For example, both sealing materials are nitrile rubber, which are interchangeable; If the sealing material of 24V solenoid valve is fluoroplastics, and the actual medium temperature is 150℃ steam, and the 220V solenoid valve is nitrile rubber, they are not interchangeable, but the appearance and structure of the two solenoid valves are exactly the same, so be sure to confirm the sealing material.

2. "Just unscrew the 220-volt coil and replace it with a 24-volt coil." Of course, this sentence is not completely correct. According to the analysis of specific working conditions, in many occasions, the 22V solenoid valve coil can not directly replace the 220V solenoid valve coil, and the electromagnetic force generated by the replaced coil is small, which may affect the normal use of the solenoid valve.
