JY41W不銹鋼氧氣截止閥采用材質(zhì)優(yōu)良的硅黃銅或不銹鋼鑄造而成，具有機械強度高，耐磨損、安全性好等優(yōu)點。使用在氧氣管路上，具有**的防爆阻燃性能，消除了氧氣管路上的不安全因素。   
氧氣截止閥屬于強制密封式閥門，所以在閥門關閉時，必須向閥瓣施加壓力，以強制密封面不泄漏。當介質(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，法蘭截止閥的介質(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，關閥門的力小，而開閥門的力大，閥桿的直徑可以相應地減少。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。
