I haven't built a phenumatic in a while, and spring is spring along so I figured I will make one. 
B. 10' 4'' tank with dual modded sprinkler valves, plumed with hardlines(1/2'') and then activated with a 2'' piston valve. 
I decied to go with B. I will make the 4'' piston valve in the summer when I have time to get the parts for it. 
So now I need to deiced weather to have 2 sprinkler valves activated by a 2'' piston valve, or go with 2 piston valves(2'' in and 1'' or 1 1/4'' out)
            
			
													What to build.
A comes from your desgin, 4'' in and 3'' out. And on B the piston valve will activate the sprinkler valves.rmich732 wrote:A couple of questions about the first two:
A) Is that a 4" porting piston valve?
B) Are the sprinkler valves actuating the piston valve, or vise versa?
Humm,I could do 2 piston valves, 2'' and 1'' out, like sprinkler valves.

Go with "A" Bigger is always better.You can't go wrong with a 4" piston valve.
            
			
									
						Well, I think I am going to go with something smaller. I might try twin 10' 3'' chambers, and then 3 2'' in and 1'' out pisotn valves. 
In the summer when I start working I want to build dual 4'' 10' chamber, with 2 4'' in and 3'' out piston valves.
Suggestions, commets??

Or you could finish that hybrid you're always talking about.

The 4'' piston is out until the summer time.
So now it is going to be a 10' 3'' chamber with 2 modded sprinkler valves that are activated by a 2'' in and 1'' out piston valve. And it will be plumbed with hard lines.
