三、进口美标不锈钢闸阀产品特点
①美标铸钢闸阀产品设计制造符合美国国家标准ANSIB16.34，美国石油学会标准AP16D和API600要求。
②美标铸钢闸阀结构紧凑、体积小、刚性好、密封安全可靠。
③美标铸钢闸阀关闭件（闸板）采用弹性结构，在工作中能自动补偿由于异常负荷或温度引起的阀体变形。因此，密封可靠，并且不会产生闸板楔柱。
④美标铸钢闸阀公称通径大于等于NPS1011，压力级400磅级和公称通径大于等于NPSS611、压力级600～2500磅级的手动阀门，其操做装置中配有滚动轴承，启闭轻松。
⑤美标铸钢闸阀主体材料、内件材料、填料、垫片、紧固件的材料可根据用户要求或实际工况条件合理组合。
⑥美标铸钢闸阀阀座可为更掀式阀座，可任意组合与关闭密封面材质配对，以满足工况要求，延长使用寿命。

① The design and manufacturing of American standard cast steel gate valves comply with the requirements of American National Standard ANSIB16.34, American Petroleum Institute Standard AP16D, and API600.

② The American standard cast steel gate valve has a compact structure, small volume, good rigidity, and safe and reliable sealing.

③ The American standard cast steel gate valve closure component (gate plate) adopts an elastic structure, which can automatically compensate for valve body deformation caused by abnormal loads or temperatures during operation. Therefore, the sealing is reliable and will not produce gate wedges.

④ American standard cast steel gate valves with a nominal diameter greater than or equal to NPS1011, pressure class of 400 pounds, and manual valves with a nominal diameter greater than or equal to NPSS611, and pressure class of 600-2500 pounds, are equipped with rolling bearings in their operating devices for easy opening and closing.

⑤ The materials for the main body, internal components, packing, gasket, and fastener of American standard cast steel gate valves can be reasonably combined according to user requirements or actual working conditions.

⑥ The American standard cast steel gate valve seat can be a more lift type seat, which can be freely combined and matched with the sealing surface material to meet the working conditions and extend the service life.
