在美国尼伯科的Nacogdoches工厂里的硅酮润滑剂
Silicone Lubricants in Nacogdoches Plant

美国尼伯科的Nacogdoches工厂内生产的青铜闸阀、截止阀、止回阀和球阀采用了下列两种方法：
Below lists the two ways in which NIBCO bronze gate, globe, check and ball valves are manufactured in our Nacogdoches plant:

1. 标准阀门：
   Standard valves:
   所有额定压力的青铜闸阀、截止阀、止回阀和青铜球阀都是在美国尼伯科位于美国德克萨斯州的Nacogdoches工厂内制造。这个工厂所生产的上列产品的任何阀门或组装的任何部件都不使用硅酮。
   All pressure rated bronze gate, globe, check and bronze ball valves are manufactured in NIBCO’s Nacogdoches, Texas plant.
   Silicone is NOT used in this plant in the production of valves or assembly of any component parts of the above listed products.
2. 可以用于氧气应用的阀门：
   Valves can be cleaned for oxygen service:
   所包含的步骤如下：
   The steps involved are as follows:
   • 在温水溶液中对所有部件进行超声波清洗以脱脂。
     Clean ultrasonically all component parts with a degreaser in a warm water solution
   • 在超声波池内进行温水冲洗。
     Rinse with warm water in an ultrasonic bath
   • 再用冷水冲洗
     Rinse again in cold water
   • 将所有部件放置在黑光下检测是否含有碳。如果发现含有碳，再重复进行上述步骤。
     Put all component parts under black light for inspection of any carbon. If carbon found, repeat steps above.
   • 组装和测试阀门
     Assemble and test valves
   • 在密封的塑料袋内包装阀门，避免受到污染。
     Package the valves in a sealed plastic bag to avoid contamination

注意：在这个工厂内组装和测试不含硅酮的阀门有可能会在出厂后的运输过程中暴露在含有硅酮的空气中。因此，美国尼伯科无法证明在Nacogdoches工厂内生产的阀门100%不含硅酮。
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 Nacogdoches plant to be 100% silicone free
