Sorry if I seemed angry, I'm not. And I mean no insult to Mr. suprise. I was just stating the reason I'm thinking of getting into the game. Actually a friend had ordered a valve, and is still waiting. he has called several times with no response, so he came to me to ask if I could make one of these. I started researching and thats how I ended up here. I had no clue how big this was until I started looking around. You guys seem to be hurting for someone who can consistantly supply a quality product. So here I am.
It will take me a few weeks to get my first valve developed (the design is there, its just hard sourcing off the shelf pvc parts on the west coast.) After I figure out what I can get off the shelf, and what I have to fab, it should go pretty quick and smooth. The thing I'm having the most troubl with is finding the bushinge he uses on the 3" T's to go from the 3" slip to 2" female thread. If anyone knows the actual part and/or manufacturer, it would sppe thing up for me......I'll go as far as to say it WILL earn you a free valve (to the first person who gets me the correct part #). for now I'm just modifying what I can find.
Anyway, that all for now. hope you all have a good and safe weeken.

Actually, the bushing is a simple 3"x2" female threaded bushing (you can buy them off of mcmaster), but the hex part is lathed off to give a smoother appearance
Almost any bushing can undergo this type of modification, and the one which Judgement Arms suggested will work

Now wait, who won? Jjk92 posted first, but he had the wrong one it’s only ¼”, but I had the right one… I did have the right one, right?
Hmm... I think Pimpmann wants to get something across.
I'll say it again then: your planned 2.5" porting would require the customer to have 2.5" fittings which are less common than either 2" or 3" fittings.
I'd personally go for making a 4" tee with 3" porting as previously suggested as neither Joel or any other site is selling that kind of sized valve wheras there are several 3" with 2" porting valves around and one more is not going to grab attention.
Joel had plans at one point to make a 4" with 3" porting but with all the orders for his current inventory I think its been shelved.
...and Pimpmann is hinting about you needing a sales rep to get it publicity.

Anyways, regarding the bushing issue, I believe this man was trying to find a flush bushing, like the one joel has. So in that regard, I should win the valve
Just kidding; Lets let him decide who the recipient will beA 4" tee valve with 3" porting would not compete with the current market; it would create a new one! I personally do not know anyone who sells a valve with 3" porting in a 4" tee; you would literally own the market
Problem is, the bigger the valve gets, the more....
1) Expensive
2) Difficult/time consuming to make
3) Chance of a failure (larger fittings=lower pressure rating; make sure to strongly reinforce whatever the piston is slamming into)
4) Weight the piston has; find a good material/shape that will keep it relatively light (the piston on the Supah valve, in my opinion, is a great design)
I wasn't saying it again for myself I was repeating it from others earlier in the thread.

Ok, so this is exactly the info I was looking for....even if its not what I wanted to hear. I needed to know where to get the flush "face" bushing Like the one in the supah so that I wouldn't have to machine a custom piece from a stock bushing.
So, extra machine time it is. (DAMN DAMN DAMN)
I believe that means rmich 732 won...unless someone knows a part that doesn't have to be machined. the standard bushing would also require machining from the backside too....the more machine time I can avoid, the less my valves will cost.
Does anyone know what material is joel using for a piston? looks like PVC, but the color is too light grey. I'm consddering Delrin aka. Acetal (2x the price of PVC) or PVC(cheaper, but I dont know if it will take the impact)...I can figure it out, but you guys could save me some time and footwork.
Also, I'm not ignoring you pimpmann22. I'm considdering my options. I could include 3" connectors for both sides, or a 3" in and a 2"out.
If you reduce the in to a 2", it would defeat the purpose if a 2.5" valve opening. Also, I can make the valves chamber or barrel sealing....whatever you want. (its just a matter of where 1 little hole is placed and which direction thr air flows. each has advantages and drawbacks) its up to you to figure out what will work best for you)

The piston he uses is constructed out of type II PVC rod. The OD of 3" pipe is 3.5", and therefore he uses 3.5" type II PVC rod (so it will fit perfectly in that one end of the tee). He then further lathes down the 3.5" type II PVC rod to make the sliding piston.
Don't get type I; it may cost less, but is not NEARLY as impact resistant.
By the way, it takes joel 118 minutes to go from scratch to a finished product (the Supah valve)
