The models and specifications of stainless steel butterfly valves are: manual butterfly valves, electric butterfly valves, hidden stupid pneumatic butterfly valves, double eccentric butterfly valves, and triple eccentric butterfly valves.
1. Manual butterfly valve.
Manual butterfly valves are generally suitable for occasions with small medium flow and low operation frequency. It is characterized by simple structure and convenient operation, and the common specifications are DN50, DN80, DN100 and so on.
2. Electric butterfly valve.
Electric butterfly valves are suitable for large flow rates, high temperature and high pressure or perennial operation. It can realize automatic control and remote control, the common specifications are DN150, DN200, DN250 and so on.
3. Pneumatic butterfly valve.
Pneumatic butterfly valves are suitable for occasions with relatively high working conditions, such as high temperature resistance, corrosion resistance, etc. It is characterized by fast operation speed and short response time, and the common specifications are DN300, DN350, DN400, etc.
Fourth, double eccentric butterfly valve.
Double eccentric butterfly valves are commonly used in hygienic fluid control stove systems, such as the food, pharmaceutical and other industries. It is characterized by advanced structure and good sealing, and the common specifications are DN20, DN25, DN32 and so on.
5. Three eccentric butterfly valves.
Triple eccentric butterfly valves are often used in industrial pipelines, which have high requirements for the flow, pressure, temperature and density of the medium. It is characterized by complex structure, but the valve has good sealing, and the common specifications are DN450, DN500, DN600 and so on.

As of February 2020,Different types and models of butterfly valves are also different, and in the market, the electric butterfly valve is generally between 75-4000 yuan
Factors influencing butterfly valves**:
1. The primary factor is the model of the butterfly valve, and the performance and suitable pipeline of different butterfly valve models are also different. In order to be able to meet the needs of different pipes, the production and development of various models makes it possible to be used more widely in the industry. Different models and specifications, the butterfly valves sold on the market are naturally different.
2. The secondary factor is the manufacturer, the manufacturer of the butterfly valve is different, and the cost is also different, so the butterfly valve is also completely different in the market. This also makes it show a trend of different heights, after all, the production technology of different butterfly valve manufacturers and the quality of the electric valves produced are different. These factors are the key to the difference between flanged butterfly valves.
3. In addition, it is directly related to the material of the butterfly valve. There is a big difference in the performance of butterfly valves made of different materials. These include stainless steel valves, for example, which are corrosion-resistant and rust-resistant.
This type of valve often has advantages over other valves.
There are so many variety, and it's very complicated. It is recommended that you go to the encyclopedia to see. >>>More
Everyone knows stainless steel flanges.
Butterfly valve handle, as soon as you hear this name, you may still have a vague mind, but if you recall it carefully, you should also have a rough outline. That's right, the industrial aspect is inseparable from stainless steel flange butterfly valves. It adopts a unique three-eccentric structure, which is widely used in metallurgy, electric power, petrochemical industry and other important construction aspects. >>>More
There are two methods, one is to use passivation paste, which is specially used to clean short stainless steel welds, which only need to be applied to the weld for 20 minutes and wiped off; The other is for more welds, first put the workpiece into the mixture of nitric acid and hydrofluoric acid to soak and clean for 15 minutes, take it out and rinse it with water, and then put it into nitric acid to passivate for 20 minutes, take it out and rinse it clean.
Differences: 1. Different degrees of corrosion resistance: 316 stainless steel contains MO, which has better corrosion resistance than 304 stainless steel in a high-temperature environment, so in a high-temperature environment, engineers generally choose 316 material parts. >>>More
A2-70 generally refers to the bolt grade.
A2: Material classification code, "A2" indicates the material group, that is, the second group of austenitic steel A2, generally 304 class of materials, A4 refers to 316L >>>More
