美國ROSS電磁閥雙聯(lián)閥提升閥現(xiàn)貨直銷代理耐高溫型提升閥、煙氣蝶閥，最高可耐溫1000度。
閥門是管路流體輸送系統(tǒng)中控制部件，它是用來改變通路斷面和介質(zhì)流動方向，具有導(dǎo)流、截止、節(jié)流、止回、分流或溢流卸壓等功能。用于流體控制的閥門，從最簡單的截止閥到極為復(fù)雜的自控系統(tǒng)中所用的各種閥門，其品種和規(guī)格繁多， 閥門的公稱通徑從極微小的儀表閥大至通徑達(dá)10m的工業(yè)管路用閥。可用于控制水、蒸汽、油品、氣體、泥漿、各種腐蝕性介質(zhì)、 液態(tài)金屬和放射性流體等各種類型流體地流動 ，閥門的工作壓力可從0.0013MPa到1000MPa 的超高壓，工作溫度從-270℃的超低溫到1430℃的高溫。
閥門（famen）是流體輸送系統(tǒng)中的控制部件，具有截止、調(diào)節(jié)、導(dǎo)流、防止逆流、穩(wěn)壓、分流或溢流泄壓等功能。
閥門的控制可采用多種傳動方式， 如手動、電動、液動、氣動、渦輪、電磁動、電磁液動、電液動、氣液動、正齒輪、傘齒輪驅(qū)動等；可以在壓力、溫度或其它形式傳感信號的作用下， 按預(yù)定的要求動作，或者不依賴傳感信號而進(jìn)行簡單的開啟或關(guān)閉，閥門依靠驅(qū)動或自動機(jī)構(gòu)使啟閉件作升降、滑移、旋擺或回轉(zhuǎn)運(yùn)動， 從而改變其流道面積的大小以實(shí)現(xiàn)其控制功能。
