阀座锁定在阀体内
　　Seat Locked Into Valve Body
　　定位装置的侧面和阀体侧面阀座都锁定在阀体内。阀座定位器侧面底部上的凸起部分将阀座锁定在阀体内，避免出现阀座环旋转出定位位置。阀体侧面阀座有模铸肋条，镶嵌在阀座环内，并将阀座锁定在阀体凹槽内。因此阀体就可阻止阀座在阀门工作时被上下推动。阀座因此不会旋转或被“驱逐”出去。
　　Both the retainer side and the body side seats are locked into the valve body. A raised lug on the bottom of the retainer side seat locks it into the valve body, eliminating any possibility for the ring to rotate out of position. The body side seat has a rib molded into the seat ring which locks into a groove in the valve body. The body prevents the seats from being pulled up and down as the valve is operated. Seats can't rotate or become dislodged.

　　阀座引导闸板
　　Seat Guided Gate
　　在阀门闸板运动的全过程中，密封面都对闸板提供恒定的引导，保持与闸板连续稳定的接触。不存在金属对金属的接触，因此也就不可能出现闸板问题的困扰。阀座与填料密封功能是分别起作用，并且互相之间完全独立作用，互不干扰。这种设计结构不依赖密封填料来定位闸板，因此使得密封填料的更换更加简单。
　　The face seals provide constant guiding throughout the valve stroke, maintaining continuous contact with the gate. There is no metal-to-metal contact, therefore gate galling is impossible. The seat and packing functions are separated and totally independent of each other. The design doesn't rely on the packing to position the gate, making packing replacement easier.

　　材质选择
　　Choice of Materials
　　重型铸造阀体材质可选用304、316或317不锈钢。闸板、阀杆和阀座环也可以采用不锈钢。可提供五种弹性阀座材质供选择，密封填料材质也可提供五种供选择。上部结构的标准配置是碳钢，但提供304不锈钢作为备选材质。还可提供耐腐蚀圆柱体结构供选择。
　　The heavy-duty cast body is available in 304, 316 or 317 stainless steel. The gate, stem and seat rings are also stainless steel. Five options for resilient seat materials and five packing options are available. The standard super-structure is carbon steel with 304 stainless steel available as an option. Corrosion resistant cylinder construction is also available as an option.

　　执行机构和附件选择
　　Choice of Actuators and Accessories
　　美国DeZurik（德朱瑞克）双向刀闸阀可以配置手轮，链轮，锥齿轮，电动等执行器。可提供完整的执行机构附件。
　　DeZurik Bi-Directional Knife Gate Valves may be equipped with handwheel, chainwheel, bevel gear, cylinder or electric motor actuators. A full complement of accessories is available.

　　易于更换的阀座
　　Easily Replaceable Seats
　　不需要任何特殊工具或设备即可现场更换阀座。采用一把螺丝刀从凹槽中拆卸螺旋阀座定位器环。然后将阀座和O形环从阀体中拉出。
　　The seat is field replaceable without any special tools or equipment. A screwdriver is used to remove the spiral seat retainer ring from its groove. The seats and O-ring lift out of the body.
