My New HP Valve is almost done

[Koa]

Lookie what i got

this should open easier than old stock valves and give more than 35 shots off of a 12 gram in a non devolumized 00 sniper2 body

[drg]

Can't wait ...

Can you explain a little more about this valve? What makes it better for HP? What is it made of?

[Koa]

well newer stock valves..and all the aftermarket valves....excluding the CCM(CCM is slightly larger than old stock valves) have large Inputs........old stock is best for 12 grams and HP

this valve has an input smaller than stock

prototype is what we see.....the materials that i end up using will be decided on cost to us....the local sniper2 users

[Koa]

ack the Lathe Broke....its gonna take a while.....plus side is that i get to make some changes for another prototype

i wanna make the holes smaller still....see how small is too small for 450 and 850 psi


if these get working as well as i hope, im gonna need to find a place to do a run of a bunch in stainless

anyone know a good place on Oahu?

[Koa]

i just got it....now to test....need to find the right length for the valve stem.....too short..farting....too long...not enough fps

[Koa]

darn valve leaked.....found the problem...made a new one........very nice

[Koa]

I LOVE GOOOOOOOOLLLLLLLD!!!!!!!!!!!!

after testing it with a mini reg about 300-350...no gauge, i got 100fps more than my fav stock valve pictured here on the right http://www2.hawaii.edu/~koa/stuff/ValveTop.jpg

and the valve on the right gets 50 fps more than the valve on the left at 450 psi, and that valve gets 50 fps more than normal stock 99 valves with a 1/4th output

but i need to try the valve at 450 psi....but before i do ill just be doing straight bulk tank CO2, then 12 gram efficiency tests

[Koa]

ok unregged CO2 testing was a mixed bag

RDL body, old valve, my valve

old valve got about 20fps more than my valve...booo boooo


my valve had a stem 1/16h longer than stock stems


cut off 3/64th off, then i tried again with old 97ish body, Fav old valve, and my valve

i got 150 fps more than fav valve



so why?  was is the stem? the 2 different old stock valves? the different air chamber?

i didnt have a chance to put that valve into RDL and vice versa...that will hopefully be tomrrow

man testing....takes a while

[Koa]

i shortened the stem and then tested it, same results.....


week later i changed the springing combination form a Blue main and a SUPER light valve, to a Yellow main and a Stock valve spring, i got what i wanted, my valve again got more shots

why? because the stock valve has more volume, so if you slam that thing open further and longer you will get more fps but the idea of my valve is to open it with the least amount of main spring tension possible, using a harder valve spring for more consistency with 12 grams, something that is difficult with lighter valve springs.

well more tests then ill finalize the design

  Still have any? I am new here, but not to pump.
  Thanks

they were never for sale, testing is still being done, until then nothing is gonna happen

[Koa]

due to the lack of demand, i will in all likely postpone any further work with my HP valve......i have my prototype and thats good enough for now.

  If you posted over at SCP http://z1.invisionfree.com/forums/StockClassPaintball/index.php?act=idx
  I bet you could get a number of them sold.

  Peace

i did......i posted a poll at SCP and MCB....very low to no responses
