What does AOP mean inside the valve? Manufacturer Model or something else?? Seek superiority. 5

Here are some of the well-known brands recognized in the valve industry, which are widely recognized and have a high reputation. While rankings may vary depending on time and market conditions, the following brands are generally considered to be among the top brands in the valve industry:

The following influential first-line brands of water system valves and industrial valves can be used as a reference, but for reference only: Suzhou Neway Valve, Shanghai Guanlong Valve, Shanghai Qizhong Valve, Sanhua, Su Yan, Shentong, Su Valve, Nanfang, Jiang.

First, the word Yao. The above manufacturers are only estimates and references, and the specific situation may vary or fluctuate at any time due to changes in a series of factors such as changes in the market, the size of the competition pattern, and the stability of product quality. As an indispensable key device in industrial production and civil facilities, the quality and reputation of the valve brand directly affect the satisfaction and trust of users.

These brands are known in the valve industry for their innovative technology, high-quality products and reliability. It is important to note that the market and industry are evolving rapidly, and different rankings may vary depending on time and region. For the most up-to-date ranking information, it is recommended to refer to industry reports, professional organizations or market research data for more detailed and accurate information.

AOP is a brand of a valve company.

The letter of the valve is the manufacturer's trademark at the top, then the valve model (including valve type, nominal pressure, nominal diameter, material and structure type), and the bottom is the casting furnace number; For details, please refer to the standard GB T308

Give an example of bai:

As shown in the figure above, the valve body of the ball valve is usually marked with the following contents:

The logo of the brand DAO of the ball valve

The diameter of the ball valve is large and small, such as the capacity of DN200 in the picture above

The pressure of the ball valve, such as 16 in the above figure, means that the pressure is 16 kg, and the valve body material is 16 kg, such as the WCB in the above figure, which means that the body material of the ball valve is made of cast steel, and if the ball valve in the above picture is added with a handle operating device, the model is Q41F-16C, DN200

I'll take the DQ41F -16P cryogenic ball valve to talk about the first DU letter.

zhid means low temperature.

The first letter of all cryogenic valves is a letter abbreviation for ball valves.

The third letter 4 means flange connection.

The fourth letter 1 means that the channel position of the ball valve is two-way, the fifth letter F means fluoroplastic, the valve seat, the sealing surface or the lining material of the identification, the sixth number 16 means that the valve can withstand the working pressure of 16 kg, the seventh letter P means The nominal pressure unit [MPA] I am just an example, the valve model is generally compiled like this, and the more detailed should be a** ** The letter in ** corresponds to the meaning of different valve models.

ASA is the abbreviation of the American Standards Association, which is now ANSI.

125 is the pound grade, that is, the pressure rating: 125 pounds.

K is the material: cast iron.

1. P54 is the temperature of the valve body greater than or equal to 545 degrees, and 100V is 10MPa, which is 100 kg, and the valve is on the name brand.

2. The valve (FAMEN) is a control component in the fluid transportation system, which has the functions of shut-off, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief. Valves for fluid control systems range from the simplest shut-off valves to the most complex valves used in automated control systems. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, slurries, oils, liquid metals and radioactive media.

According to the material, the valve is also divided into cast iron valves, cast steel valves, stainless steel valves, etc.), chromium-molybdenum steel valves, chromium-molybdenum-vanadium steel valves, duplex steel valves, plastic valves, non-standard customized and other valve materials.

P54 is the body temperature of the valve body heavy rain or equal to 545 degrees, 100V is 10MPa is 100 kg.

Valves are available on nameplates.

Q stands for ball valve, 8 stands for the way in which the clamp is linked to the pipeline, 1 stands for floating ball structure, and F stands for PTFE soft seal seat.

1 2 , 1 4 valve is the meaning of 1/2 inch valve, 1/4 inch valve.

The units of 1 2 and 1 4 are inches, not other units.

1 inch = millimeter.

1 2 inches = 1 2 mm = mm;

1 4 inches = 1 4 mm = mm.

They represent the meaning of four water pipes and two water pipes.

1 2 is dn = 15mm, outer diameter =, 1 4 is dn = 8mm, outer diameter =, if you don't understand, you can read this more detailed article: "valve diameter (dn) and pipe diameter size comparison table".

The international general caliber of the valve is the national nominal diameter.

1 4 inches.

2 8 inches back = 2 points.

A=dn8(mm).

3 8 inches = 3 points = DN10 (mm).

1 2 inches = 4 8 inches = 4 points = DN15 (mm) 3 4 inches = 6 8 inches = 6 points = DN20 (mm) 1 inch = DN25 (mm).

1 1 4 inches = DN32 (mm).

1 1 2 inches = DN40 (mm).

2 inches = DN50 (mm).

"1 2 , 1 4 valves.

"Copy" is our general colloquial name. 1 2 and 1 4 refer to the diameter of the valve, and the unit is inches. And then there's 8 to 8 inches.

Relative to China, the valve caliber is expressed as "DN". There is a conversion of 1 inch = about that, so generally our 1 inch valve is a DN25 valve.

And so on. I don't know if you understand? To put it simply, these numbers are indicative of the size of the valve.

It should be said that it is the caliber that is represented, the unit is inches! 15mm 6mm nominal diameter valves representing metric units!

1 2 is 4 points caliber = 15mm 1 4 is 2 points diameter Concise.

Cast iron valves, cast steel valves, stainless steel valves, chrome-molybdenum steel valves, chrome-molybdenum vanadium steel valves, duplex steel valves, plastic valves, non-standard customized valves, etc.

These are the specifications of the valves, 1 2 corresponds to DN15 1 4 corresponds to DN8It is the caliber size of the valve.
