　　It is important to properly identify valves in service to allow for the ordering of replacement parts or address questions or concerns relating to our products. Body markings and information shown on the identification plate helps to properly identify valves, allowing timely and accurate responses to such inquiries.
　　整个阀体铸件的标记参数包括下列信息，有助于进行跟踪：
　　Integrally cast body marking data includes the following information and helps to provide traceability:

• 美国克雷恩标志
  Crane logo
• 压力等级
  Pressure class
• 阀门通径
  Valve size
• 材料等级的钢符号(例如，表示碳钢的WCB)
  "Steel" symbol for the grade of material (i.e. WCB for carbon steel)
• 熔炼炉号 - 在阀体
  Heat number – on body and bonnet (cast or stamped)
• 独立的系列号
  Individual serialization

　　阀体标记通过一个标志牌来加以补充，阀门种类和通径不同，标志牌也有所不同，并安置在最适合的地方。闸阀和截止阀的标签位置通常在阀门轭架或阀体/阀盖法兰上。止回阀标签通常安置在阀帽的边缘上。
　　The body markings are supplemented by an identification plate which, depending on valve type and size, is mounted in the most practicable position. Tag location for gate and globe valves is typically on the valve yoke or body/bonnet flange. Check valve tags are typically mounted on the rim of the cap.
