适用于所有流量控制领域的正确地解决方案
The Positive Solution For All Your Flow Control Applications.

　　美国尼伯科法兰球阀提供精确地、高性价比的工业流体控制应用方案。整体式和分体式阀体球阀其设计和制造都符合或超过ANSI, MSS和API标准。这两种结构的球阀具有下列显著的特性：
　　NIBCO flanged ball valves provide precision, performance and value for industrial flow control applications. The unibody and split-body valves are designed and manufactured to meet or exceed ANSI, MSS and API specifications. And both styles offer these outstanding features:

• 能够防止在超压状态下出现故障的压力安全阀杆的肩部结构
  A pressure-safe stem shoulder design that protects against failure under excess pressure.
• 紧密、无泄漏的工程密封和双向操作
  Tight, leakproof engineered seals and bi-directional operation.
• 适用于协调、可预测低扭矩操作的低摩擦工程密封结构
  Low-friction engineered seat design for consistent and predictable low-torque operation.
• 允许执行机构的通用安装的预钻孔和攻丝的安装座
  Pre-drilled and tapped mounting pads that allow universal mounting of actuators.
• 更加安全的、可在开启和关闭位置进行锁定的功能
  Lock-out capability in either open or closed position for added safety.
• 可配置各种材料和通径
  Available in a wide range of materials and sizes.

整体式法兰球阀
Unibody Flanged Ball Valves

• 整体式结构避免了可能出现泄漏的不必要的连接面，具有双密封端塞功能
  A unibody design eliminates unnecessary joint faces where leakage may occur, and features a double-sealed end plug.
• 增加的填料深度便于采用适当的V形环填料，防止阀杆周围出现泄漏
  Increased packing depth allows adequate V-ring packing to prevent leakage around the stem.
• 大尺寸阀杆具有超级保护功能，避免由于阀杆尺寸过小而导致在应力作用下容易出现的故障
  Large-diameter stem provides extra protection from stresses that cause failure in smaller stems.
