　　L1和M1是与吊耳蝶阀有关的数据；L2和M2是与平板蝶阀有关的数据。“C”尺寸是指弹性材料处于松弛状态下的尺寸。与管道法兰密封式正常要缩小3.2毫米。这些蝶阀设计上用于在美国国家标准化组织ANSI B16.1标准125磅级法兰（铁）和B16.5标准150磅级（钢）法兰之间安装。不需要采用密封垫， 因为阀座表面与配套法兰具有非常良好的密封效果。如果蝶阀安装在塑料或玻璃纤维法兰、法兰环或Van Stone类型法兰之间，请与我们联系获取更详细的资料。美国克雷恩建议在管道终端使用法兰盖。
　　L1 and M1 refer to Lug style valves, L2 and M2 refer to Wafer Style. “C” dimension is listed with elastomer in the relaxed condition. Approximately 1/8" total compression is required for proper sealing with pipe flanges. Valves are designed for installation between ANSI B16.1 Class 125 (Iron) and B16.5 Class 150 (Steel) flanges. Gaskets are not needed, and should not be used since the seat face seals against the mating flange. If the valve is to be installed in plastic or fiberglass flanges, flange rings, or Van Stone style flanges, consult your Crane agent or the factory for additional information. Crane recommends that a blind flange be used on end of line applications.

　　对于通径为DN65和DN125聚四氟乙烯（PTFE）阀座的蝶阀的有关尺寸，请与我们联系。“O”尺寸指的是蝶阀间隙尺寸。
　　Consult factory for dimension to 2 1/2" and 5" PTFE seated valves. “O” dimension is the valve clearance dimension.
