That's a Dunlop valve. What do you mean by use? How do you pump it up? Attach it to a wheel? Expand on "use" please...

They are also 3000$ a set... if you didn't already know that. What are you using it for?

It is the standard valve found on bicycles sold in Germany, The Netherlands and perhaps other countries. A pump that works on presta valve will work. Screw on adapters are available will fit standard automobile pumps.

The usual way I use them is,
unscrew the plastic cap, then the large nut just below it(holds the valve core in place). this lets all the air out.
next unscrew any nut at the base of the valve; so you can push it out of the rim.
dismount tire, pull the inner tube out.
toss it in the trash.
reinstall and reinflate tire with a shraeder valve tube.

You're missing out a step! In order to fit a Schrader valve you will need to drill the rim hole wider to accommodate the thicker valve stem. Isn't it curious, I do the exact opposite of you, and fit a sleeve or rubber grommet to accommodate the thinner stem of the Presta valve! it is generally recognized that Presta valves are far superior to Schrader valves!

A 50¢ adapter can be screwed on (and left on) that allows any Dunlop valve to be filled with an auto/bike pump that is fitted for an automobile/schrader valve.

Three of those bikes came from either Germany or Denmark. The other is a vintage Raleigh roadster.

You are quite a bit behind the times on pumps too. Every pump I have bought in the last 25 years has had the ability to pump up either presta or schrader by simply reversing the grommet in the pump head. You'd have to go out of your way to find a pump without that feature. I'm sure having the ability to do either presta or schrader adds significantly to the cost of the pump...like 15 cents or so. Oh, the humanity.

Urban legend if your only exposure to European bicycling is the TDF.

Sure, just let me walk the 15 miles to the gas station and use a compressor that is meant to pump up a 30 psi car tire. That'll be useful.

Not everybody buys their bicycle pumps or bike accessories at an LBS. The big box stores, the stores that sell the majority of bikes in the U.S., have lots of pumps on for sale that do NOT have any way to pump up a Presta valved tube.

If it 'twere me, I'd simply replace the tubes to match the valves on my bikes. That way, no fiddling with adapters.

Duh what's the sense in investing in a market that doesn't even really exist? Who would use a valve that provides no special advantage to the other two, but requires a special adapter? But I guess I'm not familiar with what bikers in Europe use, so to each his own...

I believe bikes in India also use Dunlop valves, but I am not sure of that. Anyone know what kind of tube valves are found on bikes sold in India or China?

Never owned a pump in India - just went to the neighborhood repair shop. Remembering over the years, I think there were 6 bike repair shops in a 1 km radius around my house - and this was true pretty much anywhere I rode. Tried to find the info off a local manufacturer's website, but no luck.
