Pneumatics Question

[mrmatheou]

Hi,

I'm a team mentor for team 2603 and we have one of our Pneumatics experts proposing an idea and wanted to make sure it was legal. Here are his comments below with a diagram explaining. Any feedback on it's feasibility would be greatly appreciated!

Here is what I am proposing.



Control of a pneumatic cylinder:



Use a 4 way 2 Position single solenoid valve for directional control of an air cylinder. At each port on the cylinder use a blocking single solenoid valve would be used to turn air on or off. The default of this valve would be passing so that when the robot is in E-stop no air is trapped. The use of these multiple valves to control a cylinder would be done in series. (Thus the flow of .3 Cv would not be exceeded)
