I'm designing a system to run three pneumatic tools in both the forward and reverse directions, selected via a toggle, and started via a pneumatic start handle to a pilot.
The start handle does not allow enough flow capacity to run all the tools through the handle itself; this is why I need to run it through a pilot instead. Each tool requires 17 cfm.
I've attached a picture of what I'm thinking I might have to do, but I have some questions.
Do I need to have two valves or is there a valve out there that could do it all?
What other considerations should I be sure to take into account?
Any tips on relief ports? Need to make sure pressure is relieved when necessary.
