进口低温焊接截止阀
品牌：美国威盾VTON
USA VTON VTDJ50PH Low-temperature Globe Valve
低温焊接截止阀主要用于管道系统在低温状态下对液氧、液氮等介质的截断或接通。该系列产品的特点：①阀门的流道为大圆弧过渡流线型，使介质在流道中的阻力较小；②填料密封双填料, 可使用在不同的场合，双填料能有效地防止冷损，从而使密封效果得到加强，保证介质不外漏，并使手轮处于常温下，启闭灵活。
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.
