Y-valves?

[D1V3R]

Since I am only a cavern diver, I usually just use a single tank setup. Because of this I have always woried about free flowing regulators or busted hoses and no way to turn them off w/o turning off my only air source.
I've been thinking recently about the use of a Y-valve on my single tank setup. I wasn't sure if the Y-valve was an old valve design (like the J-valve) and if somebody still makes a Y-valve? or, is there anybody that makes a DIN style valve that allows for dual 1st stages?

thanx for any feedback you can offer

if you are already a Cavern Diver and your diving single tank you should at least be using an H valve. What did you use for redundancy in your Cavern Class?

You can purchase modular H valves from Thermal, Genesis, several different companies. Most of them are the 200 bar whereas you have the threaded inserts that will let you use yoke or DIN regulators. I would highly recommend you purchase one if you go in any overhead enviornment.

I have some older H-valves but they are for a yoke only, and I usually always use a DIN. I didnt know there was a DIN H-valve, that would be perfect for the diving I'm doing.

Most of the H valves were of the removable doughnut (Din to Yoke) type- I cant remember one that was yoke only. The Y valves, on the other hand- Sherwood made a good one, but it was yoke only- and I'm pretty sure they are no longer available. Beauchat also made a DIN y valve, but I dont think I've ever seen one in this country. For simplicity and clean setup, you cant beat a y valve (other than the yoke problem, anyway) the H valves are really half ass, but for now that is all there is. Perhaps someone will make a mold for a DIN y valve and start making one. But dont hold your breath.

Not sure of the make, but I have seen some Y-valves around with the din-yoke conversion plug. You might want to check your H-valves more closely, could be they have this plug in them and can be used for din. I would opt for the H-valve if I had to buy some as they can be converted later on for use with manifolded doubles. The setup will cost more than a Y-valve, but it will be a lot more versatile.

I don't know who or where you got your training but in every cavern course I have seen you do not have to have a H-Valve setup you can dive with open water setup other than it is recomended that you use a 5ft or longer Octo. hose. But if you are cavern and you have a free flowing reg. you should have been trained how to breath off of a freeflowing reg. I was trained that in O.W. course. Also you should not be in the cavern more than 200' of linear penatration so you should be able to get out safe breathing off of a freeflowing reg. The H-Valve is consistant with the Intro Level diver. But I took my O.W. course in a single tank H-Valve and my Intro Course in Doubles. But I do not blame you for wanting to go with redundant set up and get used to Valve management all practice only sharppens your skills. I always try to do a skill on 1st dive and if I am diving with someone I have never dove with before then it is a must to do a skill on 1st dive to see if they are up to par and then 2nd dive will be a pleasure dive.

I was never told that I need to use an H-valve, and I know how to breath off a free-flowing regulator. But it does seem smart to have a way to shut it off especially in the case of a busted hose.

Try the following url: www.divers-supply.com Ask for Mitch-!
If they can't find what you are looking for, no-one can. I used a Y-valve prior to my cave Cert. & enjoyed the ease of use with it. I wished I still had it as it provides various methods of redundency.
Dive smart & safe-!

Theres a Divers Supply here in Jacksonville, I was ther buying some T-shirts last weekend :-D . Hopefully somebody will make a DIN Y-valve, sounds like a job for Poseidon, lol

Beuchat does make a "Y" valve in 200 bar modular DIN. It is one of the best operating valves available. At 4000 psi you can still easily turn the knob with two finger tips. It is available in the US. The only problem is the cost. Most people won't pay the price, $259. I have had 6 of them on sinlge tanks that I use for teaching. The biggest advantage of the "Y" design is that it mimicks the setup and operation of a standard manifold. You don't have to relearn valve manipulation in a different fashion.

[D1V3R]

Is this what your talking about? Its a bit different than a normal Y-valve, but It looks to be of a very nice design.

Thats pretty expensive, I'll probably buy a regulator that was made in the last 30 years before I buy one of those (still using 1975 Aqua-Lung Aquarius reg, lol)

I have a Y valve an old one a Sherwood. I will sell you Its also called a Slingshot valve. It is only used for yoke's. no DIN
