閥門是在流體系統中，用來控制流體的方向、壓力、流量的裝置。閥門是使配管和設備內的介質（液體、氣體、粉末）流動或停止并能控制其流量的裝置。
閥門是管路流體輸送系統中控制部件，它是用來改變通路斷面和介質流動方向，具有導流、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，從簡單的截止閥到極為復雜的自控系統中所用的各種閥門，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10m的工業(yè)管路用閥。閥門可用于控制水、蒸汽、油品、氣體、泥漿、各種腐蝕性介質、 液態(tài)金屬和放射性流體等各種類型流體的流動 ，閥門的工作壓力可從0.0013MPa到1000MPa 的超高壓，工作溫度從-269℃的超低溫到1430℃的高溫。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、傘齒輪驅動等；可以在壓力、溫度或其它形式傳感信號的作用下， 按預定的要求動作，放料閥或者不依賴傳感信號而進行簡單的開啟或關閉，電磁閥閥門依靠驅動或自動機構使啟閉件作升降、滑移、旋擺或回轉運動， 從而改變其流道面積的大小以實現其控制功能。
閥門的材質選擇跟閥門使用的介質有直接的關系，下表將詳細介紹閥門在各種液體介質中的材質選用對照 。
本閥門材質選用表是用來大致指出與某種流體介質接觸而發(fā)生反應時，應如何選擇適當的材料。表中的推薦不是絕對的，因為碳鋼,鑄鐵,不銹鋼,青銅,蒙乃爾合金,哈氏合金,鈦,鈷鉻合金,沉淀鋼等閥門材料的耐腐蝕性與流體的濃度、溫度、壓力和雜質等因素有關。因此，必須強調本表只能作為一個導則參考。
符號：
A - 能夠或正被成功應用
B - 應用過程應注意
C - 不能應用
LL - 缺乏資料
