6、阀体材料：WCB、SS304\SS316或者其它特殊材质
7、适用介质：水、蒸汽、油品、硝酸、醋酸、氧化性介质、尿素等多种介质。

三、进口美标闸阀产品特点：
①美标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美标闸阀结构紧凑、体积小、刚性好、密封安全可靠。
③美标闸阀关闭件（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。

Import gate valve

I. Overview of the imported gate valve
Brand: US Ouke OKE
Imported gate valve, American Standard cast steel gate valve, also known as American standard API gate valve, American standard ANSI gate valve, American standard pound gate valve, refers to the use of cast steel valve body material, manufacturing and design standards using API or ANSI American standard The gate valve is suitable for cutting and connecting the pipeline medium in the pipelines of various working conditions such as ANSI Class 150~2500 and working temperature <600 °C for petroleum, chemical and thermal power stations. Applicable medium: water, oil, gas, etc.

Second, the import of American standard gate valve parameters
1. Nominal pressure or pressure level: ANSI CLASS 150-1500LB, JIS10-20K
2, nominal diameter or caliber: DN25 ~ 1000, NPS 1/2 ~ 36"
3, connection method: flange
4, applicable temperature: -196 ° C ~ 700 ° C
5. Drive mode: manual, bevel gear transmission, pneumatic, electric, hydraulic, gas-liquid linkage, electro-hydraulic linkage
6, valve body material: WCB, SS304\SS316 or other special materials
7. Applicable medium: water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea and other media.

Third, the import American standard gate valve product features:
1 American standard gate valve products are designed and manufactured in accordance with American National Standard ANSI B16.34, American Petroleum Institute standards AP16D and API600 requirements.
2 American standard gate valve is compact in structure, small in size, good in rigidity and safe and reliable in sealing.
3 American standard gate valve closing member (throttle plate) adopts elastic structure, which can automatically compensate the deformation of the valve body due to abnormal load or temperature during operation. Therefore, the seal is reliable and does not create a gate wedge.
4 American standard gate valve nominal diameter is greater than or equal to NPS1011, pressure class 400 pounds and nominal diameter is greater than or equal to NPSS611, pressure level 600 ~ 2500 pounds of manual valves, the operating device is equipped with rolling bearings, easy to open and close.
5 American standard gate valve body materials, internal materials, fillers, gaskets, fasteners materials can be reasonably combined according to user requirements or actual working conditions.
6 American standard gate valve seat can be a more sturdy valve seat, which can be matched with the material of the closed sealing surface to meet the working conditions and prolong the service life.

Fourth, the import of American standard gate valve standards:
