三、進口美標閘閥產品特點：
①美標閘閥產品設計制造符合美國國家標準ANSIB16.34，美國石油學會標準AP16D和API600要求。
②美標閘閥結構緊湊、體積小、剛性好、密封安全可靠。
③美標閘閥關閉件（閘板）采用彈性結構，在工作中能自動補償由于異常負荷或溫度引起的閥體變形。因此，密封可靠，并且不會產生閘板楔柱。
④美標閘閥公稱通徑大于等于NPS1011，壓力級400磅級和公稱通徑大于等于NPSS611、壓力級600～2500磅級的手動閥門，其操做裝置中配有滾動軸承，啟閉輕松。
⑤美標閘閥主體材料、內件材料、填料、墊片、緊固件的材料可根據(jù)用戶要求或實際工況條件合理組合。
⑥美標閘閥閥座可為更掀式閥座，可任意組合與關閉密封面材質配對，以滿足工況要求，延長使用壽命。

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.
