How to manually control a solenoid valve switch
Thread Content
Gentlemen, I would like to ask how an electromagnetic valve can be connected to the manual buttons in the field control box in order to manually open and close the pneumatic valve. Thank you all
The on-site button box can be equipped with a remote/local switching button.
The solenoid valve controls the operation of the pneumatic valve by being energized/de-energized. Disconnect one of the wires in the power supply circuit of the solenoid valve, and connect a switch there arbitrarily. It is suggested that a technical improvement report be prepared for such matters and submitted. It’s best to let professionals handle professional matters. For reference.
The solenoid valve comes equipped with a forced button, and it can also be forced remotely. Isn’t it unnecessary to add a local switch?
Which solenoid valve comes with a forced button? It only knows how to be controlled by a 24V power supply.
To enable local manual switching, a 3-core cable is required from the control room to the field box, with 2 channels of 24V+ for common – connections.
It’s very simple – just add a switch, just like with controlling a light bulb. If you want to do it formally, add a button relay; generally, solenoid valves already come with manual operation buttons, so those can be used directly
