Which brand of DN150 feed water direct buried gate valve is better?

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.

DN150 feed water direct buried gate valve, we have the production here. I don't know what material you need for that? How much stress?

DN15 four points, 20 six points, 25 one inch, 32 inches two, 40 and a half inches, 50 two inches, 63 two and a half inches, 75 three inches, 90 three and a half inches, 110 four and a half inches.

For a detailed comparison of how big an inch of water pipe should be used, see the following table:

1. Pipe fitting size inch millimeter comparison table.

2. A detailed comparison of how big the valve diameter (interface) should be used for the water pipe, see the following table:

<>3. A detailed comparison of how big the water pipe (large outer diameter) should be used and how big the valve diameter (interface) should be used, see the following table.

Summary. 1. The globe valve has good sealing, and the gate valve can be selected if it is normally open, and the globe valve is best if it is closed for a long time, especially the imported bellows globe valve of Weidun VTON. 2. The gate valve is suitable for full opening and closing, but it cannot be opened to half, or it will not damage the gate, but the pressure drop is small, the stop valve can be opened to half, and it can also play a role in adjustment, but the pressure drop is large, and there is a little erosion, and the sealing is better than the stop valve.

3. Compared with gate valves, the advantages of globe valves are simple structure, good sealing performance, and convenient manufacturing and maintenance; The disadvantage is that the liquid resistance is high, and the opening and closing forces are high. 4. The application range of globe valves and gate valves is determined according to their characteristics. In the small steam channel, when good shut-off sealing is required, the inlet shut-off valve is mostly used; In larger steam pipelines, inlet gate valves are used because the fluid resistance is generally small.

5. It is especially recommended to use bellows globe valve, double seal, which has a good effect on the steam pipeline.

These two are chosen on a case-by-case basis, and each has its own advantages and disadvantages. I'll give you a list here, I hope it will help you.

The gate valve is suitable for full opening and full closing, but it cannot be opened to half, or it will not damage the ram, but the pressure drop is small, the globe valve can be opened to half, and it can also play a little adjustment role, but the pressure drop is large, and there is a little erosion, and the tightness is better than the key pin valve. 3. Compared with Qingyou gate valve, the advantages of the globe valve are simple structure, good sealing performance, and convenient manufacturing and maintenance; The disadvantage is that the liquid resistance is high, and the opening and closing forces are high.

4. The application range of globe valves and gate valves is determined according to their characteristics. In the small steam channel, when good shut-off sealing is required, the inlet shut-off valve is mostly used; In larger steam pipelines, because the fluid resistance is generally small, the imported gate bright die valve is used. 5. It is especially recommended to use bellows globe valve, double seal, which has a good effect on the steam pipeline.
