密封類型軟密封除耐腐蝕的襯里閥門外，一般的軟密封閥指閥芯或閥座兩者之一采用非金屬材料（主要為聚四氟乙烯和橡膠等）的密封形式的閥。軟密封閥密封效果比較好，但在管道安裝、系統(tǒng)的清洗中都有可能留下或多或少不干凈的雜物（如焊渣、鐵屑等），它們流經(jīng)調(diào)節(jié)閥時，容易把軟密封閥座或閥芯劃傷，使泄漏量增加，密封可靠性差。所以，選擇軟密封結(jié)構(gòu)必須考慮介質(zhì)的清潔和投運前嚴(yán)格沖洗管道。硬密封硬密封再堆焊耐磨合金是切斷閥的比較好選擇。這種方式在考慮密封性的同時也考慮了使用壽命和可靠性，雖然出廠指標(biāo)只有10-4～10-5，達(dá)不到軟密封零泄漏的效果，但足以滿足嚴(yán)密切斷的要求，而且它經(jīng)久耐用，從經(jīng)濟(jì)的角度考慮更合算。此外還需要注意以下兩點：1）對密封可靠性的考慮：軟密封，切斷效果好，但不適宜用于顆粒介質(zhì)，一旦劃傷，泄漏會急劇增加。因此，條件允許時盡量選用硬密封。“O”型球閥硬密封可達(dá)10-5，三偏心蝶閥可達(dá)零泄漏。2）對密封耐磨性的考慮：除選硬密封外，對泄漏要求10-4以上的切斷型調(diào)節(jié)閥，必須堆焊耐磨合金以提高密封的耐磨性、耐沖蝕、耐劃傷的能力，提高閥的壽命。
