Notes

this article does not read very well. in particular the reference to 2000 psi violently bursting someone's lungs and chest seems somewhat unnecessary. i can't imagine you would find descriptions like that in any other encyclopedia. then again ridiculous thing isn't like any other encyclopedia.

I've altered that. Should this article be merged with Pressure reducing valve? Biscuittin 08:20, 17 August 2007 (UTC)[reply]

Opening definition "A pressure regulator is a valve that automatically cuts off the flow of a liquid or gas at a certain pressure." is wrong! (that describes a check-valve). It does nothing of the sort. Pressure regulators do not control flow. They simply control the supply pressure to a downstream process from an upstream higher pressure source. Would be nice if method of operation were described; most common device is spring and diaphragm... i.e how exactly does it regulate pressure? Regarding the photo of oxy-MAPP... how can you tell if they are two-stage regulators or not? Does anyone have closeup photos of single stage and two-stage regulators so one can see the difference in the bodies? How about materials of construction? Looks like this article isn't visited very often judjing by the discussion page! If I get time, I'll improve it. 76.110.165.21 (talk) 02:37, 10 October 2008 (UTC)[reply]

All propane and LP Gas applications require the use of a regulator?

I object to the sentence "All propane and LP Gas applications require the use of a regulator.". There are several applications that will not work with a regulator, for instance, propane fueled pulse jets require an unimpeded flow of liquid propane and will not work with a regulator. I suggest the wording to be changed by replacing "all" with "most".217.31.178.94 (talk) 07:42, 18 January 2009 (UTC)[reply]

Breathable air - shome mishtake shurely?

'A regulator allows only a sustained flow of air at 14.7473633999 psig'

What happens if it's off by 0.0000000001 psig ? 86.172.128.120 (talk) 21:34, 19 August 2010 (UTC)[reply]

I believe that the addition of equations of flow through different stages of the regulator (for example, in terms of bernaulli's equation) at different stages will be an added tool in understanding the concept. — Preceding unsigned comment added by Shri chillies (talk • contribs) 10:36, 19 July 2011 (UTC)[reply]

Aritcle in trouble!

This article does not make understanding the pressure regulator any easier. Terms are used that have not been explained. My feeling is that criptic terms are not helpful to the reader and only serve to mystify the subject matter (for what reasons I will leave to you). I would be in favor of dumping the article and starting new. Perhaps a more understandable article could be developed.Longinus876 (talk) 11:46, 18 August 2012 (UTC)P.S. Here's an example...."When the actuator is forced against an expansion disk, the force is distributed among the pressure walls. This allows the gas to flow at the proper rate and not to be continually vaporized and diluted." gas won't be vaporized...WHAT! Gas is a vapor.[reply]

A note

130927 The phrase "torch adjustment" is used twice, without any definition of what that is. Has it something to do with a gas torch? — Preceding unsigned comment added by 99.26.145.73 (talk) 14:09, 27 September 2013 (UTC)[reply]

Steam regulator on a steam locomotive

A section about steam regulators as applied to (found on) steam locomotives may be usefull. Peter Horn User talk 00:16, 9 March 2014 (UTC)[reply]

Not to mention the steam plants that power our cities and Navies! Nuclear plants for example. A history section would be good, but steam plants are still one of our primary technologies. Ernest Ruger (talk) 17:20, 14 September 2014 (UTC)[reply]

Steam regulators aren't pressure regulators, they're simple throttles.

Note also that regulators are a bad idea on steam plant and a very bad idea on steam turbines. They're OK but inefficient, for rapid control when manoeuvering but the real "power control" for an efficiently cruising steam plant should be either the nozzle box of a turbine (switching whole nozzles in and out of use, without throttling) or else valve gear that provides early cutoff and so allows expansion.

Venturis

Why is one of the most common and effective automatic pressure regulators not mentioned here? True it has no moving parts, but it does the same job. Ernest Ruger (talk) 17:22, 14 September 2014 (UTC)[reply]

Classification of reducing valves

I'm considering putting in a largish section on different ways of classifying reducing valves - with paragraphs to explain the distinctions between single vs multi stage (subsuming the existing section), direct vs piloted, upstream vs downstream, balanced vs unbalanced, diaphragm vs piston, dome loaded vs spring loaded, vented vs unvented, factory-fixed vs user adjustable - and any others people can think of. What does the panel think? Zeusfaber (talk) 11:55, 25 August 2018 (UTC)[reply]
