We would like to clamp some airline and instead of using the manual screw ones we would like to switch it on and off electronically. Does anyone know of any ???
What application are you using this on? I can't think of any cost effective ways to achieve what you are describing off the top of my head, but would it be possible to just put the air pump on a timer and use a check valve if necessary to prevent siphoning?
If you have a pump pushing whatever is going to flow through the airline you can put that pump on a controller plug in or timer. All depends on what you want to do.
I'm guessing that by "clamp" you mean "valve". If so, you are looking for a solenoid valve. Check this site to see if this is what you are looking for: Solenoid Valve Basics
