Talk:Valve seat

promo link?
I have removed the following link from this article:
 * www.coherix.com/auto/surfacedetective/Technical%20Foundations%20and%20Heritage/Shapix%20Surface%20Detective%20Carl%20Aleksoff%20%20SPIE%20Paper.pdf

It is intentionally unlinked as I believe the inserter is intending to promote his/her product. The contents of the PDF lead into a promotion of a product. I am listing it here for others to review, however, because it does contain other information that might be useful. I leave it to others to determine whether it should be included. --AbsolutDan (talk) 16:38, 13 November 2006 (UTC)

Broaden scope
Valves occurring in any pipework or pipeline have seats as well, yet the article only talks about engines!--86.12.160.194 (talk) 14:01, 23 April 2019 (UTC)
