Unread postAuthor: squidchicken » Mon Apr 11, 2011 12:45 am

hey guys I tried searching this up but probly noobed out and couldnt find anything related. need to know if i would get a good performance increase if I had a faster pilot valve, currently im using a ball valve, but i think its kinda weak. Any suggestions on the pilot valve, was thinking about a qev but i knda wanted something like mrr's DCV valve

What type of gun are you trying to pilot? A ball valve should suit you fine on most things unless it a giant 4inch porter. What size is the gun and ball valve that you are using now?

How much advantage depends on your main valve. A small ratio valve will remain closed until the pilot pressure is very low so it will pop open. A wide ratio valve needs a high flow pilot valve to prevent the valve from partially opening or closing right after it opens.

In a narrow ratio valve, too small of a pilot volume can hinder it opening all the way.

See the Wiki page on Piston valves
