美国 EVERLASTING 公司成立于 1904 年，专注于生产
耐磨损、耐腐蚀和频繁开关的工业阀门。阀门的结构是 EVERLASTING的自有***。
产品系列包括：
Everlasting BMV
Everlasting Process
Everlasting Diverter
产品特点
由于 Everlasting 阀门自身结构的特点，使其在耐磨损、耐腐蚀和耐高温高压领域显示出独特的可靠优势。阀门结构形式是Everlasting 的***技术（ U.S.PATENT 5,396,919） ( 见图 1) ， 即：圆盘偏心转动结构 。这种结构形式的阀门在世界上是的，它特性非常明显。其它的耐磨损阀门是靠选择阀门材料来解决磨损问题，而 Everlasting 是靠阀门 结构 + 材料 来解决磨损问题。
Rotating Disc Valves include hard metal sealing surfaces fhandling abrasive, erosive slurries dry powdered media. Open body allows free flowing media fines to be displaced by moving parts, therefore no packing jamming.
