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
