Call the industry to unify inflation valves

[CaptainKook]

Here's a spreadsheet I've made to collect some data about the mess we have in the kite's industry

https://docs.google.com/spreadsheets/d/ ... sp=sharing

What I really desire is that all bars use low V split. High V split has nothing to contribute imho.

CrazyFly are
Node Loop Loop Node
V
Inflation valve 3

[Peter_Frank]

Flysurfer Peaks does not have 4 nodes.
They could also be labelled as 4 loops, or 2 loops 2 nodes or reverse.

They have universal "node or loop" whatever you like, at the kite
Dont know about other Flysurfer kites though....

Takoon have Loop Node Node Loop.
And Valve 3 / Adapter 3 the classic Boston like many has.
Some Takoon kites has high V, newer ones low V - I dont care it doesnt matter what the kite is born with, I hate low V myself so avoid these at all cost.

It doesnt matter whether kites are node or loop or high or low V, takes a few minutes to convert loop/node.

But the valves are important IMO - I wish all had Boston, but we dont agree about this.
On the excel it shows Valve 4 usea adapter 1 - I think this is wrong, valve 4 is the one that does not need an adapter, and adapter 1 is the special Duotone a few tenths of a mm different diameter.

Agree that Duotone Valve1 and the one without adapter Valve4, has its drawbacks as you need to rotate the pump hose precisely, which can be difficult.
But in theory I love the idea of "no adapter needed".

PS: Naish also has Valve 3 / Adapter 3 on earlier models, before the 2 / 2 now, so "year" specific.

The Duotone valve on a friends kite is a pain in the ass... almost everytime when you detach the hose, the inner ring rotates along, so it starts to lose air again. Rubbish design if you ask me.

It's designed to automatically close and open the valve when you plug and unplug the correct adapter. If it's happening the valve has some malfunction and should be fixed or replaced.

I think it's a clever design since it works in an open state while pumping and has this "automatic" open and close feature, however, it's a proprietary design and we must have the specific adapter to make it work properly.

[knotwindy]

Yes and that’s the problem. Proprietary designs are to help the company, not the user. Better designs are based on the users ease and function.

If you buy a duotone pump, the bayonet at the end of the hose will work with duotone and mini Boston valves.

So in my case duotone and slingshot and I have friends with Cabrinha. All good.

But as we found out the hard way, the valve adapter for a f-one wing would not work with the duotone hose bayonet mount.

And my wmdg pump hose bayonet is too thick to attach to the duotone valve.

So maybe it is the pump and adapter manufacturers that need to get their act together,

The valve rotates clockwise to open and counter clockwise to close. So as you twist the hose counterclockwise to remove the hose, it closes the valve.

So the inner ring has to rotate along with the hose.

Whatever the kites vale’s is please make them work with one adapter. You are welcome to be innovative about your push / turn / sliding valve mechanism but have one common part which makes them work with ONE interface.

Valve 4 (Cabrinha, Elev8 and North) will need an adapter depending on the pump you have.

I'll give you an example. Get this pump and try to inflate a valve 4 based kite.

(I have this pump. It doesn't fit very well on valve 4 and instead of forcing the hose to enter the valve, I'd rather use the adapter)

but I understood your point. The image shown on my spreadsheet for the adapter is not good. It's a kind of "recursive adapter" when I should have illustrated just the tip of the hose (the right side of the adapter)

In fact, the only "no adapter" valve is Boston. Just a bare tube with the correct diameter should be enough, but a hose with a slightly conical tip helps a lot (an adapter)

I get the feeling it rotates clockwise, but not back far enough. I'll check closer next time. Friend is having a winter sleep now.

Still I think a good valve shouldn't have those kinds of problems.

As said before, pumps almost every single one, comes with bayonet at the end

A kitesurfer borrowed my pump the other day, and I asked which connector he needed - noone he said he just plugged the bayonet on and twisted to lock

Boston always needs an adapter.
Good thing though, it's the most common adapter (apart from the beach ball tiny one) this big conical one.

But now I can understand only some type 4 valves fit?
If so, a new type must be defined.

And no sorry I can't remember his kite brand...
