Hi,
Schoolboy error, I purchased a couple of cheap solenoids (airtac 3v210-08 12v) from AliExpress, looks like I got internal pilot operated ones when I wanted direct.
When I apply voltage it clicks and I can see it drawing the correct current but the valve doesn't move.
In laymans terms how do you make an internal pilot actuate, apply pressure to the inlet, if the inlet always has pressure how do you switch it, by removing the voltage, why is a pilot solenoid better for automation?
Basically I want to switch the path of air between two destinations and I want to just apply voltage to the solenoid to have it switch paths, my valve will never be closed it will either be on path A or path B, what do I need?
Thanks.
