Talk:Globe valve

I have level control valve designed to have equal percentage charcteristics plug but I think it is not sutible for our application can we convert this charc. without changing plug by controlling the output signal from controller and change it sq. root ?!!!

Diagram
The diagram is improperly labelled, the part refered to as the disc is actually called the plug; on other valve types, this component may be referes to as the disc (perticularily the butterfly valve) 192.139.190.6 15:23, 16 March 2007 (UTC) Marty(process engineering student)
 * I'm a chemical engineer with training and experience in plant engineering and fluid systems including valves such as globe valves, etc. in the United States. In my experience, I've always heard the valve part in question referred to as a "disc" (or "disk" with alternate spelling).  On Feb. 15, 2007, User:Ian Nelson expanded this Globe valve article and changed all instances of "disc" to "plug" in the article.  On Aug. 20, 2007, the existing Reference 1 had a diagram under the heading McGraw Hill Architecture showing the part in question labeled as a "disc", as well as the aforementioned small diagram shown in the article.  I did a quick search on the net with "globe valve" and "disc" and got 55300 hits, most (of a random sample) of them referring to that part called a "disc" or "disk" in a globe valve.  A couple of these I inserted as references into the article to show that the part is called a "disc" or "disk"; see References 3, 4, and 5 in the Globe valve article.  According to my experience, plugs are corresponding cylindrical or conically-tapered parts for controlling flow in plug valves (a different type of valve).  See also "Plug valve" in Engineering Wikia for a picture.  Reference 2 in this Globe valve article does refer to this equivalent part as a "plug" and shows a conically-tapered disc in two diagrams of globe valves; I'm guessing this is an Australian reference.  I also did a quick search on the net with "globe valve" and "plug" and got 89100 hits.  Some of them referred to the part in question as a "plug" in globe valves, but many of them were just lists of valves which included "globe valve and "plug valve", which means that web page was not referring to the part in question as a "plug".


 * Based on the above finding, the labeling of the disc in the diagram in the article is correct. I edited the article to use "plug" as the primary term used for this part, but mentioned "disc" and "disk" as terms used for this part, along with additional references I added.  I may someday replace that diagram with a larger, better diagram.  H Padleckas 18:32, 20 August 2007 (UTC)  H Padleckas 10:23, 21 August 2007(UTC)


 * After some poking around, it looks like the reqdiagram was added before the nice illustration was added to the page. I believe that it fills the requirement, so I have removed the reqdiagram tag. Egmason (talk) 11:40, 22 May 2014 (UTC)

What's the difference?
...between a globe valve and a gate valve? Their photos look fucking same.--Mazarin07 (talk) 09:39, 7 February 2008 (UTC)

gate valve, is a valve that opens by lifting a round or rectangular gate/wedge out of the path of the fluid but the globe valve is a type of valve used for regulating flow in a pipeline, consisting of a movable disk-type element and a stationary ring seat in a generally spherical body. this is so clear. in this photo you must consentrate on the lump of globe valve. Because of this lump that it's named gGLOBE valve — Preceding unsigned comment added by Saeed mirzazadeh (talk • contribs) 21:25, 29 June 2011 (UTC)
 * Externally many different types of valve look very similar, but different internal mechanisms result in different characteristics regarding the amound of flow restriction when fully open, the quality of the seal when closed, the level of tolerance for operating in a partially open configuration and the level of tolerance for wear. -- Plugwash (talk) 22:22, 29 May 2019 (UTC)

globe valve
it's so greate to explane about use of globe valve in HVAC and in special usage of globe valve in boiler's. in hot water boiler's we have two main valve : one in sent circulation water too radiator's and another one in recive water from radiator's. — Preceding unsigned comment added by Saeed mirzazadeh (talk • contribs) 21:20, 29 June 2011 (UTC)
