This vavle should work shouldnt it? Second can you drill your hole for the air fitting somewhere besides the center because if i do the spring on the inside wont have any where to sit.

i was just wondering...

i don't quite understand how the blowgun trigger moves the diaphragm. i was wondering if you could clarify that for me?

there is pressurized air on both sides of the diaphragm, using the blowgun you exhaust the air on top of the phragm, so there is no pressure above, and your chamber volume is still pushing from below, that pushes the phragm up and allows the air go to to the barrel

Hmmm, how to explain without getting complicated. A sprinkler valve works on the property of pressure diferences. When you fill the gun, the air goes through an equalization hole in the diaphragm, and keeps it seated. The area that keeps the diaphragm down is called the pilot area. The solenoid vent the pilot, but not nearly as fast as possible. So by putting the blowgun there, you exhuast the pilot faster, and that means the valve open faster. If you need any help, you can im me on AOL or MSN.

EDIT: Spudshot beat me. :(

I havent been able to find the valve at any hardware store. What isle at Lowes should I look in. I know it is not in the pipe area, so where should I look?

How big of a difference is there in a modded sprinker valve and a normal solenoid one? I'm going to keep using the solenoid though. I much prefer an electric fire.

10x faster, but u can keep both triggers, if u do it right, the solenoid doesnt bother you at all.

Is the number acctualy "10x"? I'm not so sure of that number, but I'd like to check - what is the flow provided by one of those solinoid valves?

Will this make my seloniod valve stop makeing that really loud noise like an airhorn?
