截止閥（stop valve,Globe Valve）的啟閉件是塞形的閥瓣，密封面呈平面或錐面，閥瓣沿流體的中心線作直線運動。閥桿的運動形式，有升降桿式（閥桿升降，手輪不升降），也有升降旋轉(zhuǎn)桿式（手輪與閥桿一起旋轉(zhuǎn)升降，螺母設(shè)在閥體上）。截止閥只適用于全開和全關(guān)，不允許作調(diào)節(jié)和節(jié)流。
截止閥屬于強制密封式閥門，所以在閥門關(guān)閉時，必須向閥瓣施加壓力，以強制密封面不泄漏。當(dāng)介質(zhì)由閥瓣下方進入閥六時，操作力所需要克服的阻力，是閥桿和填料的磨擦力與由介質(zhì)的壓力所產(chǎn)生的推力，關(guān)閥門的力比開閥門的力大，所以閥桿的直徑要大，否則會發(fā)生閥桿頂彎的故障。近年來，從自密封的閥門出現(xiàn)后，截止閥的介質(zhì)流向就改由閥瓣上方進入閥腔，這時在介質(zhì)壓力作用下，關(guān)閥門的力小，而開閥門的力大，閥桿的直徑可以相應(yīng)地減少。同時，在介質(zhì)作用下，這種形式的閥門也較嚴密。我國閥門“三化給”曾規(guī)定，截止閥的流向，一律采用自上而下。
