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:
