進(jìn)口低溫焊接截止閥
品牌：美國(guó)威盾VTON
USA VTON VTDJ50PH Low-temperature Globe Valve
低溫焊接截止閥主要用于管道系統(tǒng)在低溫狀態(tài)下對(duì)液氧、液氮等介質(zhì)的截?cái)嗷蚪油āＴ撓盗挟a(chǎn)品的特點(diǎn)：①閥門(mén)的流道為大圓弧過(guò)渡流線(xiàn)型，使介質(zhì)在流道中的阻力較��；②填料密封雙填料, 可使用在不同的場(chǎng)合，雙填料能有效地防止冷損，從而使密封效果得到加強(qiáng)，保證介質(zhì)不外漏，并使手輪處于常溫下，啟閉靈活。
Low-temperature Globe Valve is mainly used for truncating or connecting the liquid oxygen, nitrogen and other media at low temperature. Product features: ① flow valve streamlined for large arc transition, the medium in the flow resistance in the smaller.② Double packing filler, can be used on different occasions, two filler can effectively prevent cold damage, so that the seal has been strengthened to ensure that the media does not leak, and to hand wheel at room temperature, open and close flexible.
