H Valve Suggestions

[thomschoon]

I have the need for a couple H Valves, taking a class and I can use my HP120’s instead of twins if the cylinders have H Valves, looking for suggestions on best solution and supplier.

Thanks for the help

DR/DGX?

DGX?

I've got the DGX brand also and had zero problems. Great price and got it in 1 day shipping inside Florida.

My suggestion would be twins if the course you are considering is AN/DP or Tech40. Yes the standards say you can dive with an H valve but in real world terms that won't be enough gas for the kinds of dives you'd want to do after the course.

I dove larger steel cylinders with H-valves for years, but diving seemed so much easier with I swapped my big single tank(s) with H-valve to a set of small (read: 50 cf steel) doubles. The low profile and reduced drag was a huge plus, and suddenly I could do valve drills every dive.

I thought about doubles but then I need to change a lot more gear, I am going to do advanced nitrox& deco, more for the base knowledge and won’t be doing any long deep or cave dives so will stick with singles.

Your approach is not unreasonable. When I did AN/DP with my wife she was learning doubles and had hard time managing the change. Later we learned she could have done the course with a single cylinder with a H valve. That would have been better for her.

I should note that we had h valves on our single cylinders for a while. Then we decided that it was simpler to have a double rig kit and a singles rig kit. That made life easier. Of course now we also have DIN/Yoke single rig kit too. So be careful as regulators multiple when not looking.

I used an HP130 with H-valve for many years and it worked well for me. If you are not doing cave or long deep dives I would say it is a good choice. I still use H-valves on my HP 100's which I have switched to as my body gets older and I am also using LP 50's for sidemount.

That's fine for the repetitive air dives you'll likely do on course. But gets extremely marginal once you start looking at 32/O2 dives where you will be needing 3 tanks anyway.
Better to learn in the hardest configuration unless you want to relearn it all later.
