Have any of you tried this?

Off course it's a copy/improvement/whatever you want to call it.

The difference is the use of Draeger Dolphin mushroom valves & holders (makes sense using these). I don't know how the barrel o-rings are laid out, but probably the same. The second stage is the same (sepiadiver).

It was only logical that people would copy Krolaks design - with lead times of over a year you can not expect competition not to fill the gap.

guys,

@ at narked at 90:
apart from your using differant mushroom valves have you over come the problem with using the second stage valve in the housing you have? mainly over breathing the valve unseats the valve arm.
I´m not sure if I understand what it means: ....over breathing the valve...., - can you explane it to me?
thanks,
kind regards,
peter

Sorry to jump in here but I'm interested. John is referring to breathing in sharply and deeply and quickly which will move the valve lever too far and jam it to it does not function any longer. Known fault with some of these models.
John, and a lot of other people are watching yours with interest as it may solve a lot of the problems they have encountered. The similarity of your valve excites that they may be able to use some of your parts to remedy their own BOV from Filip.
The price of many of the BOV's are somewhat more than yours which will always create interest.

Brent.

sorry for not replying earlier(work never stops)
the problem i was referring to, as dive the world staited...thanks mate...
is that on the ATX second stage body there are two plastic lugs that stop the valve arm from being displaced, these are not in the second stage that Filip used and as a result a very sharp deep inhale can unseat the valve arm and it simply stops delivering gas(just when you need it most)
i know this happens as it happens to my DSV,
sorry about the picture quality, i have high lighted the plastic lugs so you get what I'm talking about.
kindest regards john routley

I think I received one of the the latest Nemotech DSV's from Filip, and I just took a picture of the second stage.

Unfortunately it's not easy to machine these kind of lugs in - so they are not there. The small bar (2) should prevent the lever from unseating, but then you never know.

When doing maintenance, it may be wise to remove the lever with great care, so it gets not bent further open than necessary.

Thanks John for the tip - nice to know this.

All the mouthpieces i have been looking at does have the exhalation through the rubber membrane, im reffering to the cis lunar MP, krolaks, and blackgear.
Does anyone know if it is possible to buy these rubber membranes with exhaltion in the middle.
Are the " off the peg" or are they custom made?

Regards Allan

hi steven it would be very hard to machine in the lugs but i can be done, im working on a fix for these dsv's but im snowed under working on kiss meg stands and a new project to be relised very soon......
also if your having problems getting a negative test then remove the 4 locking screws that hold on the second stage and put a little bit of ptfe tape on the threads or a very small oring on the screw, as this is a cause of a lot of the problems as the screws are the wrong side of the sealing o-ring
i think you have the same dsv as me. it also locks solid in cold deep water!
kind regards john routley

hi,
let me attach a picture, so anybody can figure out what´s the difference and how it´s made.
@ rogerinebo
the mushroom valves are made in the original version - that they could not been exchangend in the direction inhale/exhale site - just for savety issues. but - the modification to make them exchangeable would be easy.
second stage regulater is an apex atx50
the inhale/exhale diaphragm and the covering of the regulator comes from sepadiver.
kind regards,
peter

Nick uk. · 1st March 2006, 21:10

Ok, but do you make it to fit an insporation, or would i have to modifie it myself to fit the hoses. And what sort of LP. hose attachment is used for the second stage?

It looks exactly as the old style nemotech - except that on the newer style nemotech barrel o-rings were added (In cold water the plug expands because of warm breathing, housing contracts because of cold water -> difficult to turn. Barrel o-rings prevent this.)

Might want to investigate adding orings around the holes in the plug.
