美国克雷恩闸阀能够可靠稳定的应用在蒸汽、空气、煤气、油、油气和高压等应用场合。所有流道都是直线通过流道，确保湍流、侵蚀和流动阻力降到最小程度。这种阀门可配置宽广系列的阀内件。
　　Crane gate valves offer the ultimate in dependable service for steam, air, gas, oil, oil vapor, and high pressure installations. All have straight-through ports to assure minimum turbulence, erosion, and resistance to flow. They are available in a wide variety of trims.

1. 阀体：阀体是铸件，具有足够的强度满足工作环境的要求，流体流动不会受到阻碍。湍流，侵蚀和压降减少到最小程度。
   法兰连接端口 - 美国克雷恩铸钢闸阀具有法兰连接端口和对焊连接端口两种连接方式。所有法兰和对焊连接端口结构都符合ASME B16.5和ASME B16.34标准。
   Body: Body is cast to provide liberal strength to meet operating conditions and to permit unobstructed flow. Turbulence, erosion and pressure drop are minimized. Flanged End-Crane cast steel gate valves are available in flanged end and butt weld ends. All flanged and butt welding end valves are designed to conform to ASME B16.5 and ASME B16.34 standards.
2. 整体轭架和阀盖：一些结构有两件式阀盖和轭架组成。所有阀盖构件都是铸件，并且按照严格的一致的公差标准进行抛光，使得阀体与阀杆能够准确校准，密封更加容易。阀盖连接方式从平面垫圈连接到环形阀盖连接，压力等级不同，连接方式也有所不同。
   Integral Yoke & Bonnet: Some designs incorporate a twopiece bonnet and yoke. All bonnet assemblies are cast and finished to the same exacting tolerances as the bodies for accurate alignment of stems and ease of sealing. Bonnet joint varies from flat face gasket-joint to ring-type bonnet joint, depending on class.
3. 阀座环：阀座环境过密封焊接，可消除环后的泄漏通道，延长无故障工作的寿命。表面经过精密研磨以精确配置阀瓣。
   Seat Rings: Seat rings are seal welded to eliminate leak path behind rings and for long trouble-free service. The surfaces are precision ground to fit accurately with the disc.
4. 阀瓣：美国克雷恩一件式弹性阀瓣能够精确对准以适合阀座表面，这样阀门能够吸收化解管道应力，避免出现泄漏。此外，还避免卡住在阀座里的可能性。这种阀门也配置实心楔形阀瓣，并经过几百万个实际应用的成功考验。
   Disc: Crane's one piece flexible disc provides accurate alignment of mating seating surfaces so the valve can absorb piping strains without leakage. Also, it avoids any tendency to stick in the seated position. Valves are also furnished with solid wedge discs that have proved successful in millions of applications.
5. 阀杆：T形阀瓣-阀杆连接防止施加在阀杆侧面的应力，确保操作平稳顺畅容易。轭架套管准确的螺纹连接有助于阀瓣位置的调整控制。
   Stem: The tee-head disc-stem connection prevents lateral strain on the stem for smooth, easy operation. Accurately cut threads engage the yoke sleeve for positive control of disc position.
6. 轭架套管
   Yoke Sleeve
7. 手轮螺母
   Handwheel Nut
8. 轭架套管锁紧螺母
   Yoke Sleeve Retaining Nut
9. 填料：填料内含防腐剂，避免锈蚀阀杆。深度填料函确保较长的填料使用寿命。
   Packing: Packing contains corrosion inhibitor to avoid stem pitting. Stuffing box is deep, assuring long packing life.
10. 压盖：压盖为两件式球形结构，将压力均匀地施加在填料上，不会造成阀杆弯曲。
    Gland: Gland is a two-piece ball-type which exerts even pressure on the packing without binding the stem.
11. 压盖法兰
    Gland Flange
12. 压盖有眼螺栓：有眼螺栓可以从旁边旋起，使得填料函的填料更换更加容易。
    Gland Eye Bolts: Eyebolts swing aside for ease in repacking the stuffing box.
13. 压盖有眼螺栓螺母
    Gland Eye Bolt Nuts
14. 阀盖垫圈
    Bonnet Gasket
15. 阀盖柱头螺栓：阀门通径和压力等级不同，螺栓的数量也有所不同。
    Bonnet Studs: Number is dependent on valve size and class.
16. 阀盖螺母：阀门通径和压力等级不同，螺母的数量也有所不同。
    Bonnet Nuts: Number is dependent on valve size and class.
17. 有槽销钉
    Groove-Pin
18. 阀盖衬套
    Bonnet Bushing
19. 手轮：美国克雷恩闸阀也可以配置齿轮或马达执行机构。
    Handwheel: Crane gate valves can also be supplied with gear or motor operators.
20. 液压润滑油注入器：液压润滑油注入器为轭架套管轴承表面提供润滑(没有图示)。
    Hydraulic Grease Fitting: Hydraulic grease fitting provides for lubrication of yoke sleeve bearing surfaces (not shown).
