Re: Pistons only halfway up

I'm not sure of the technical terms to use, but in 2010 we used a solenoid that normally kept both sides closed unless one side was activated. It was paired with a very large pneumatic cylinder to be used as a lifting arm. It raised and lowered fine, and you could even stop half way. We never got it fully functioning though.
