message: In the section Valve#Two-port_valves it is stated that "examples of normally-closed (NC) valves are sampling valves"; this is correct. However, "Examples of normally open (NO) valves are isolation valves", this is not correct, imho. I engineering, typically isolation valves will be NC because in case of a problem (e.g. no power supply) they should close automatically. Even if they are open during normal operation, they are officially NC valves. I will change that if there are no objections. Dvh369 (talk) 09:14, 21 September 2011 (UTC)

thread_title: Type of Valves

message: I unlinked switch because 1) valves are not usually understood as switches and 2) the switch article is only about electrical switches. I unlinked "flow" partly because there is no longer an article about flow, and partly because, as I think it would be impossible to make a reasonable article called "flow", I don't want to encourage the creation of a new one. --Ryguasu 00:39 Dec 3, 2002 (UTC)

message: It would be extremely helpful to include more images especially engineering cutaway type diagrams (the kind you might find in a valve manufacturer's catalog) of standard valve types ( ball, gate, check, butterfly, globe, plug, needle, guage) pointing out applicable features, ( flange, raised face flange, stem, disc, wafer, bonnet, spring, ball, port, trunion mount, threaded connection, handwheel etc.). Excellent (but proprietary) examples are contained here:

message: In the article, it is stated that 2-port valves are always 2-way. This is untrue and very confusing for the article
I suggest changing the articles from 2,3,4-way valve to 2,3,4-port valve.
The line mentioned needs to be deleted. 
Finally, 1 port valve needs to be added and the article made.
It should be mentioned in the valve operating positions section that Return valve and Non-return_valves exist.  —Preceding unsigned comment added by 91.176.13.194 (talk) 12:09, 4 June 2009 (UTC)

message: Could someone provide a definition for "industrial valves" please?
I find the term confusing as it is sometimes used to define valves used in the industry (chemical, power, oil & gas). Other times it is all encompassing. Thus when it comes down to water it is not clear whether the term covers water & waster as well or solely industrial water.  —Preceding unsigned comment added by 83.228.42.158 (talk) 09:18, 5 April 2011 (UTC)
thread_title:  Industrial Valves 

message: I think the classification done over here is somewhat confusing as is wrt there way of operation by solenoid/hand/fluids etc; it would be more systematic and easy to understand different types of valves if these are classified wrt principle of operation viz. linear or rotary etc. Please have a look at this link; if you like the idea you may improve the article accordingly.JPMEENA (talk) 04:37, 5 November 2012 (UTC)

message: The paragraph two-port valves says this "Some valves are specially designed to regulate varying amounts of flow. Such valves have been called by various names such as regulating, throttling, metering, or needle valves." I think the name is proportional valve. Besides, it should probably not be in this paragraph.  — Preceding unsigned comment added by 86.91.158.142 (talk) 13:53, 15 August 2014 (UTC)

message: Image top right has caption "These water valves are operated by rotary handles.". The words "rotary handles" are internally linked to "handle". Shouldn't just "handles" link to handle instead? Also, the word "rotary" isn't mentioned anywhere else in the article. And when I look up "rotary handle" (with quotes) at Google Images, there's not a single Google image that includes a valve that looks even close to the Wikipedia image. And I mean literally nowhere, until I scroll all the way down, and Google says "Looks like you've reached the end". --2001:1C06:19CA:D600:4D1B:ED1E:813:7A67 (talk) 20:20, 11 October 2023 (UTC)
