I have a 1/2" DC12V solenoid valve wired to the PDP and PCM through a SSR. I have a flyback Diode integrated in the wiring of the solenoid. I have two 5 gallon air storage tanks that I can pump up to about 120 psi. In my code I have my pulse rate set to a fraction of a second, but when the solenoid is fired, its staying open for longer than the pulse rate. Is it a limitation of the solenoid? Does Pressure have to drop before it can close? Do I have to set some sort of off signal?
This is for a T-shirt cannon. We can get a really good shot off, then a moderate shot, and then we’re basically out of air. I think the next best step would be to route a regulator between the air tank and the tube to the solenoid, but if I could regulate just as well from switching the solenoid we’d be set to start mounting all the hardware.
