The type of rotary valve I am looking for is not for a musical instrument. The rotary valve I am interested in is used in the Petrochemical industry. I would imagine the concept is similar, but we need a more discriptive illustration showing the mechanics of the operation.

See: www.fielddevices.com item: Positioners

The diagram of a rotary valve is absolute horrendous and does not in any way lead to a better understanding of what it does, nor does it reveal anything about how it works. Perhaps someone in the know could improve or suggest a more appropriate diagram. Imacdo 19:55, 26 December 2006 (UTC)[reply]

Trumpet[edit]

So, in the case of the rotary valve trumpet... does this system make it sound different (I know it does) or make it easier to play (not really) or anything else? And there are several things called rotary valves. This article is about the musical ones. I think this article needs a good fixing! 75.48.30.247 (talk) 21:29, 27 August 2010 (UTC)[reply]

Scope[edit]

There doesn't seem to be enough material in this article to split this into "Rotary valves on musical instruments" and "other Rotary Valves". I don't see why this article should be specific to musical instruments when Piston valve is not. I agree that the article needs a good re-organisation, and I can do this and add some diagrams if necessary. There's also an issue of overlap between this article and Four-way valve (this article has an awful diagram too).

I propose to reorganise this article in generic terms and add it to Wikipedia:WikiProject_Chemical_and_Bio_Engineering (there's no reason why it couldn't also remain on musical instruments, or be added to any other project). I'll start work on this in November unless there is any dispute. Wikiwayman (talk) 11:26, 18 October 2010 (UTC)IS A GR[reply]

Engine Design.[edit]

It would be sensible to split up two stroke and 4 stroke engines as the application is utterly different. 84.92.147.189 (talk) 04:25, 13 February 2021 (UTC)[reply]

Airlock Internal Link[edit]

Is this intended to refer to Rotary Airlocks used for feeding materials in industry? — Preceding unsigned comment added by Eric Lotze (talk • contribs) 22:52, 26 February 2024 (UTC)[reply]

Having read both articles, it looks like that was the intention, because only a few airlocks are based on a rotary valve principle. That said, the Rotary Airlock article has some issues with inconsistent naming that are very confusing if a reader is directed from this article to that one. Best thing to do would be to check that the usage of "rotary valve" on the Rotary Airlock page is both correct and commonplace. If so, this article needs to be amended to include that specific use of the term. If it isn't correct, then the airlock article needs some work. Wikiwayman (talk) 13:32, 27 February 2024 (UTC)[reply]
