3寸氣動蝶閥

This model was made by a brazilian company named RTS (http:www.rtsvalvulas.com.b2009/home-ENG.asp), it's a standard air operated butterfly valve with a 3 inches diameter. For obvious reaso I did not include the internal components (I would have to disassemble the whole thing and waste a lot of time).If you want to know whats iide it, check this catalog here, it will give you an idea.http:www.kitz.co.jp/english2/pdf/E-357-09.pdfhttps:en.wikipedia.org/wiki/Butterfly_valve
