Talk:Pilot-operated relief valve

In the diagram 'Cutaway view of PORV' the pilot tube is labelled 'pitot tube', which is confusing and wrong. A pitot tube would be pointing directly into the direction of flow. I do not know how to edit the diagram: I leave that to those with more experience. 106.69.240.142 (talk) 06:23, 2 March 2017 (UTC)Chris Carter

Just noticed the same thing. You are correct. The opposite error sometimes occurs on things relating to aircraft, where a mysterious pilot tube appears. It is a SVG file. I will look into how it can be edited. Tiger99 (talk) 15:50, 16 January 2019 (UTC)

Had a look through the help system, and I am no wiser about how to fix it, or how the small image gets derived from a much larger SVG, which is the one that needs to be fixed. I can't locate the information that is needed to fix it. It is easy to insert an image, but beyond that is a mystery to me as of now. Sadly I will have to leave it for now, and hope that someone with the necessary knowledge or experience comes along soon. Tiger99 (talk) 16:07, 16 January 2019 (UTC)
