设计和结构
Design & Construction

　　美国DeZurik（德朱瑞克）不锈钢刀闸阀设计用于启闭应用场合。这种阀门的特点在于其铸造耐腐蚀304或316不锈钢阀体。阀杆和填料密封装置同样采用不锈钢，具有耐腐蚀性能。这种不锈钢刀闸阀可提供的通径范围为DN50~DN600，带金属阀座。
　　DeZurik Stainless Steel Knife Gate Valves are designed for on-off applications. They feature a cast corrosion resistant body in 304 or 316 stainless steel. The stem and packing gland are also stainless steel for corrosion protection. Stainless Steel Knife Gate Valves are available in sizes 2"-24" with metal seats.
　　有各种各样的执行器可供选择，包括手轮，链轮，锥齿轮和缸体。还可以提供完整系列的附件。
　　A variety of actuator options are available including handwheels, chainwheels, bevel gears and cylinders. A full complement of accessories are also offered.

不锈钢阀杆
Stainless Steel Stem

　　所有阀门都配置不锈钢阀杆，确保操作容易，性能可靠。
　　All valves are furnished with a stainless steel stem that assures easy operation and dependable service.

一体式铸造、耐腐蚀阀体
One Piece Cast, Corrosion Resistant Body

　　重型、铸造304或316不锈钢阀体具有很强的耐腐蚀耐磨损性能，能够经受最恶劣的液体泥浆和干燥物体介质的处理应用场合。所有不锈钢阀体、阀腔和填料腔等所有与流体介质接触的部件都采用坚固耐用、一体式结构。整体金属阀座所具有的关断性能优于美国阀门及配件工业制造商标准化协会MSS-SP-81标准。
　　The heavy duty, cast 304, 316 stainless steel body provides corrosion and abrasion resistance on the toughest liquid slurry and dry material handling applications. The all stainless body, chest, and packing chamber provide durability and integrity for all wetted parts. The integral metal seat provides shutoff that exceeds MSS-SP-81 standards.

坚固的闸板导轨和夹子
Rugged Gate Guides and Jams

　　闸板导轨为活动闸板提供支撑。闸板夹子位于阀体底部，将闸板安全的控制在阀座上，确保有效的关断。
　　Gate guides provide support for the moving gate. Gate jams at the bottom of the body hold the gate securely against the seat to assure positive shutoff.

整体凸耳阀体
Integral Lug Body

　　凸面阀体上带有钻孔和攻丝凸耳，其尺寸大小符合美国国家标准化组织ANSI B16.5压力等级150磅级的钻孔尺寸标准。
　　Raised face body has drilled and tapped lugs in accordance with ANSI B16.5 150 Lb. drilling dimensions.

经久耐用的填料
Long Life Packing

　　可提供多种材质的填料供选择，以在最小填料密封装置压力下确保密封紧密。最高温度极限值根据材质的不同而在260^oC至537^oC之间变动。
　　A variety of packing materials are offered to assure a tight seal with minimum packing gland pressure. Maximum temperature varies from 500^oF to 1000^oF dependant on material type.

耐腐蚀填料密封装置
Corrosion Resistant Packing Gland

　　填料密封装置采用耐腐蚀的不锈钢材质。填料密封装置的螺栓很容易被操作，以便于调节。
　　The packing gland is stainless steel for corrosion resistance. Packing gland bolts are easily accessible for adjustments.

高流量
High Flow Capacity

　　圆形端口流道结构符合美国阀门及配件工业制造商标准化协会MSS-SP-81标准，可以在最小压降下拥有很高的流量。阶梯式转换端口流道避免出现空穴现象（空穴处容易出现杂质淤积）。
　　Round port design per MSS-SP-81 requirements allows high flow capacity and minimum pressure drop. A stepped transition port eliminates the cavity (where material can accumulate).

坚固耐用的不锈钢闸板
Rugged Stainless Steel Gate

　　闸板采用304或316不锈钢材质，可用于耐腐蚀应用场合。闸板两面均经过精密精磨加工，避免损坏填料和阀座。闸板的斜面刀形边缘能够将杂质排出或切割流体介质中的固体颗粒。
　　Gates are available in 304 or 316 stainless steel for corrosion resistance. They feature a precision ground finish on both sides to prevent packing and seat damage. The beveled knife like edge pushed aside or cuts through solids in the flow stream.

附件
Accessories

　　作为标准配置还提供各种附件。包括：缸体执行器附件，作为定制的阀门/执行器总成，以满足特定的应用要求。
　　A variety of accessories are offered as standard. Including cylinder actuator accessories for customizing the valve/actuator package to meet your specific application requirements.
