在流體管道系統(tǒng)中閥門是控制元件，其主要作用是隔離設備和管道系統(tǒng)、調節(jié)流量、防止回流、調節(jié)和排泄壓力。由于管道系統(tǒng)選擇**適合的閥門顯得非常重要，所以，了解閥門的特性及選擇閥門的步驟和依據(jù)也變得至關重要起來。閥門承壓件材質鑄銅、鑄鐵、球墨鑄鐵、高硅鑄鐵、鑄鋼、鍛鋼、高（低）合金鋼、不銹耐酸鋼、哈氏合金、因科鎳爾、蒙乃爾合金、雙相不銹鋼、鈦合金等。并且能夠生產(chǎn)各種電動、氣動、液動閥門驅動裝置。面對如此眾多的閥門品種和復雜的各種工況，要選擇管道系統(tǒng)**適合安裝的閥門產(chǎn)品，首先應了解閥門的特性；其次應掌握選擇閥門的步驟和依據(jù)；再者應遵循選擇閥門的原則。閥門的特性一般有兩種，使用特性和結構特性。1、使用特性：它確定了閥門的主要使用性能和使用范圍，屬于閥門使用特性的有：閥門的類別(閉路閥門、調節(jié)閥門、安全閥門等)；產(chǎn)品類型(閘閥、截止閥、蝶閥、球閥等)；閥門主要零件(閥體、閥蓋、閥桿、閥瓣、密封面)的材料；閥門傳動方式等。2、結構特性：它確定了閥門的安裝、維修，阿克蘇球閥的價格，阿克蘇球閥的價格、保養(yǎng)等方法的一些結構特性，屬于結構特性的有：閥門的結構長度和總體高度、與管道的連接形式(法蘭連接，阿克蘇球閥的價格、螺紋連接、夾箍連接、外螺紋連接、焊接端連接等)。</p><div
