We are using this single action cylinder (https://www.mcmaster.com/6498K273/) and this solenoid (CKD Single Solenoid Valve with Fixed Wires - AndyMark, Inc). We wanted to know if:
is it legal to only have one tube from the solenoid go to the cylinder; the other fitting on the solenoid being replaced with an M5 bolt as a way to prevent flow when the solenoid switches states; the other fitting on the cylinder being left open to have the spring side fill with air.
is there anything that we can purchase to prevent debris from getting into that open side of the cylinder we left, such as a fitting that is just a mesh, that is FRC legal.
The idea is to only use air for one actuation, as the other is done with the spring, to conserve air.
