NIB-SEAL® Technical Data
美国尼伯科有限公司

　　安装NIB-SEAL®保温手柄美国尼伯科青铜球阀是保持保温管道系统完好无损的唯一方法。
　　NIBCO bronze ball valves installed with NIB-SEAL® insulated handles are the only approach that keeps your insulated piping system completely intact.
　　具有创新功能的NIB-SEAL青铜球阀能够防止冷凝和冷却。独特的热障结构设计阻止水分渗透到保温系统中，防止热能从暴露的金属手柄上流失。
　　The revolutionary NIB-SEAL bronze ball valve stops condensate, cold. Its unique thermal barrier design keeps moisture from infiltrating your insulated system while preventing thermal energy loss through exposed metal handles.
　　NIBSEAL青铜球阀专为新安装或现存系统的更新而设计，对于普通的商用暖通空调系统及工业应用中的需要保温的管道系统来说，具有许多的优点。
　　Designed for new installations or retrofitting existing systems, NIBSEAL bronze ball valves offer a wide range of advantages for typical commercial HVAC systems as well as industrial applications where insulated piping is desirable.

  • 保护套提供一个附加在保温材料上的固定的表面，允许在不损坏保温系统的整体性基础上进行阀门的操作和维护。
    Protective sleeve provides a stationary surface to affix the insulation, allowing operation and maintenance of the valve without destroying the integrity of the insulated system.
  • 高强度圆柱形手柄结构具有易于调节用于系统平衡的止动记忆装置的特点。阀门填料也易于进行日常的维护保养。
    High-strength cylindrical handle design features easy access to standard adjustable memory stop for system balancing. The valve packing is also readily accessible for routine maintenance.
  • 盖子和保温塞用于蒸汽封闭，防止气体交换，保持保温管道系统的高效运转。
    Cap and insulating plug provide a vapor seal to prevent exchange of air, to maximize the efficiency of your insulated piping system.
  • 位置指示器使得操作者能够一眼看出阀门是处于开启还是关闭的位置。
    Position indicators allow at-a-glance determination of whether valve is in open or closed position.
  • 预制的孔使得标记简单方便。
    Preformed hole allows for convenient tagging.
