Talk:Valve stem

per AfD, invisible tire valves should be merged here[edit]

Per Wikipedia:Articles for deletion/Invisible tire valves, the article in question should be merged here. --wwwwolf (barks/growls) 11:35, 3 February 2008 (UTC)[reply]

Presta[edit]

The Presta valve is thinner and is typically only found on road bikes and more expensive bicycles because they can take more pressure. They are also known as "Peugeot" valves, because Peugeot bicycles used to be sold with this sort of valve.

As many (most?) mountain bikes now have Presta valves should this be changed? MikeWJones (talk) 21:28, 13 July 2008 (UTC)[reply]

Invisible valves[edit]

I ve never seen or heard of this, at least in bycicles. Even if they exist they are getting more prominence in this article than they deserve. Maybe put in an extra section for "others" and put in invisibles and for example the regina valve (used in Italy: http://www.schwalbe.com/ger/de/allgemein/drucken/abstract/?ID_Gesamt=30) --Kricket (talk) 11:19, 19 May 2009 (UTC)[reply]

did it myself... --Kricket (talk) 11:24, 19 May 2009 (UTC)[reply]

I've never seen an invisible valve either. --scnr

Move?[edit]

The result of the move request was moved to Valve stem –Juliancolton | ^Talk 00:55, 24 August 2009 (UTC)[reply]

Valve stem (tire) → Valve stem — disambiguation is redundant, no other article with the same name; disambiguation page is also redundant, because there's only one alternative use of the term "valve stem" thus a hatnote is appropriate per WP:D#Disambiguation page or disambiguation links?; (tire) is misleading, as the article is for a device used for many non-wheel/tire applications; (tire) is inaccurate, as valves are fitted to wheels (specifically, to rims or tubes), not tires. — 58.8.12.37 (talk) 22:17, 16 August 2009 (UTC)[reply]

move - I'll second the comments made above by 58.8.12.37: move Valve stem (tire) → Valve stem and add a hatnote. -AndrewDressel (talk) 13:00, 17 August 2009 (UTC)[reply]

Support per nom. Use a hatnote to disambiguate. — AjaxSmack 02:36, 18 August 2009 (UTC)[reply]

move with hatnote - EdgeNavidad (talk) 07:32, 19 August 2009 (UTC)[reply]

What type of valve stem is this?[edit]

I have seen (too much, when I was a schoolboy, with bicycle wheel punctures) plenty old-type tires with inner tubes where the valve was attached not to the wheel but to the inner tube, and protruded inwards radially through a hole in the wheel rim. Anthony Appleyard (talk) 05:51, 17 August 2009 (UTC)[reply]

Could be any of the types listed - Schrader, Presta, or Dunlop/Woods - all are used as bicycle inner tube valves. If it can be inflated in exactly the same manner as with a car, with a garage forecourt airline (intended for cars) without the need for an adapter, that's a Schrader. If the tip of the valve has to be turned anti-clockwise (undone) to permit inflation, and then turned clockwise (tightened) to seal, that's a Presta. If the stem has separate upper and lower halves, held together by a knurled collar, that's a Dunlop/Woods. 58.8.211.187 (talk) 14:31, 17 August 2009 (UTC)[reply]

Proposal: merge this article into Tire#Valve stem[edit]

I see no advantage in the material in this article remaining separate from section Valve stem in article Tire. Layzeeboi (talk) 01:36, 27 June 2017 (UTC)[reply]

Oppose - they are used in other applications besides tires: refrigeration and air conditioning systems, plumbing, engine fuel injection, suspension systems, and SCUBA regulators. -AndrewDressel (talk) 02:11, 27 June 2017 (UTC)[reply]

Withdrawn — I also realized that there are other applications and was withdrawing this proposal when I hit an edit conflict with the above comment. Layzeeboi (talk) 02:15, 27 June 2017 (UTC)[reply]

Terminology question[edit]

The valves discussed here (at least all of the common types) are poppet valves. It seems uncontroversial that when describing poppet valves, the thin rod attached to the plug is called the valve stem. So, is there another name, less ambiguous, for the piece of equipment being discussed in this article? (Even reversing the words and calling it a "stem valve" might be sensible, but that doesn't mean anyone calls it that.) Or are we just satisfied to talk about a valve stem that has a valve stem inside it? TooManyFingers (talk) 21:30, 13 August 2023 (UTC)[reply]
