Thread: manifold type solenoids or individual solenoids?

Tweet

I have a chance to get a manifold solenoids for pretty cheap, and there are 8 solenoids on it (5 port/2 position). I know if I use a manifold, I will have to run 2 air lines to the prop. But it would be much cheaper than buying 8 different solenoids. Would I run into any problems with running with the manifold type, or should I just stay with the individual solenoids?

If you use double acting cylinders you would have to run 2 lines any way, 1 for extend and 1 for retract. If there isn't any pressure issues, meaning one prop needing more than another, then the manifold is the way to go. You might have to watch the distance the prop is from the manifold. If there are different pressure requirements you can place a regulator after the individual solenoid to provide the correct pressure. Another thing to look at is the flow of the solenoids on the manifold, make sure it is enough to run the prop same goes for the size of the compressor. In my opinion I like to keep everything together as much as I can. Triggering each solenoid might be an issue also.

The only downside to using this set up is with a air hog prop that has a cylinder firing over and over each time it's activate. If you have simple pop up props there shouldn't be any problems.

I like running a 3/8 or 1/2 air hose to my manifold when I have two or more props that could be fired at the same time. Each valve has their own wiring so triggering them shouldn't be a problem. The only thing you are sharing is the supply side air and the exit exhaust
