We have a double-acting piston (the one that is not spring-loaded) and were wondering if there was a way to close the a and b ports in the solenoid independently. Right now, since the port is on by default, it is always pulling the piston in. When we press b on our controller, it opens b as well, and it pushes against the air coming from a to open the piston. Then once we let go, it instantly goes back down since a is always open.
TLDR; Is there a way to close the solenoid ports a and b independently?
