高壓閥：指工稱(chēng)壓力PN 為10～80Mpa的閥門(mén)。(5) 超高壓閥：指公稱(chēng)壓力 PN≥100Mpa的閥門(mén)。按工作溫度分類(lèi)：(1) 較低溫閥：用于介質(zhì)工作溫度 t<－100℃的閥門(mén)。(2) 低溫閥：用于介質(zhì)工作溫度－100℃≤t≤－40℃的閥門(mén)。(3) 常溫閥：用于介質(zhì)工作溫度－40℃≤t≤120℃的閥門(mén)。(4) 中溫閥：用于介質(zhì)工作溫度120℃(5) 高溫閥：用于介質(zhì)工作溫度t>450℃的閥門(mén)。按驅(qū)動(dòng)方式分類(lèi)：(1) 自動(dòng)閥是指不需要外力驅(qū)動(dòng)，而是依靠介質(zhì)自身的能量來(lái)使閥門(mén)動(dòng)作的閥門(mén)。如安全閥、減壓閥、疏水閥、止回閥、自動(dòng)調(diào)節(jié)閥等。(2)
