Yes, too much pilot volume is a common problem. A larger pilot valve does help, though it's best to try to reduce this volume somehow, either by re-designing the valve or filling the volume with something (foam anyone?).octane89 wrote:Can someone answer this for me-
Is it possibly to have too much pilot volume? I have a 3" Tee, and the pilot volume is about the size of a 3" cap.
A picture would be helpful...
Peace,
Pete Zaria.
I'll have a pic soon and better explanation, but It's a new type of sealing piston Im working on, and where the piston slides back is the pilot volume (obviously), but I don't want to restrict the flow by not having it open enough.
Here's a pic to help get an idea of what Im doing.

- Here's what it looks like together. The cap and tee will be held together by a 4" coupling.

Octane, the disc that seals with the barrel needs to be the same diameter as your rear disc otherwise it won't be stable and won't work.

The co-axial animation is working for me, your talking about the one on the front page right?f.c wrote:the coaxial design doesn't seem to be showing up just my luck considering i needed it.

Not sure why it wouldn't be working, Try <a href="http://gbcannon.com/flash/coax.swf">this link</a>f.c wrote:the coaxial design doesn't seem to be showing up just my luck considering i needed it.
Also the theory behind all of them is the same, so using another one would probably still let you learn the concept.
