在美国阿肯色州的工厂内的铸铁阀门上，采用硅润滑剂
Silicone lubricant usage in Iron Valves at the Blytheville, Arkansas Plant

　　多转铸铁阀门：闸阀、截止阀、角阀和止回阀
　　Multi-turn Iron Valves: Gate, Globe, Angle and Check
　　在美国阿肯色州生产的阀门中，只有止回阀在组装期间采用硅润滑剂。硅酮是以润滑脂的形式使用，应用在阀座上。
　　Of the valves that are produced at the Blytheville plant, the check valve is the only type that uses silicone during assembly. The silicone used is in the form of grease, and is applied to the seat.
　　注意：在美国阿肯色州工厂内组装和测试的阀门没有使用硅润滑剂，但是仍然有可能在出厂后的运输过程中暴露在含有硅的空气中。因此，美国尼伯科公司不能够保证在美国阿肯色州工厂生产的阀门100%不含硅。
　　NOTE: Valves that are assembled and tested without silicone lubricants in this plant have a potential exposure to air-born silicone as well as during shipping after they leave the plant. Therefore, NIBCO cannot certify valves produced in the Blytheville plant to be 100% silicone free.

特别制作的止回阀：
Special Ordered Check Valves:

　　根据用户的要求，我们能够以所谓的“干式组装”的方式组装止回阀。这些阀门的组装不使用硅润滑剂。
　　We will, upon request, assemble check valves that are described as “Assembled-Dry”. These valves are assembled NOT using the silicone grease.

　　美国尼伯科止回阀可以安装在水平管道或流向朝上的垂直管道的任何中间位置上。当倾斜度不超过15^o时，也能够令人满意的工作。
　　NIBCO check valves may be installed in both horizontal and vertical lines with upward flow or in any intermediate position. They will operate satisfactorily in a declining plane (no more than 15^o).

　　注意：不要在往复式空气压缩系统内使用。
　　WARNING: Do not use for reciprocating air compressor service.
