Who knows what features the manual butterfly valve D71X 16 has?

1. This valve adopts double eccentric structure, which has the sealing function of tightening the closer and tighter, and the sealing performance is reliable.

2. The sealing sub-material is made of stainless steel and nitrile oil-resistant rubber, which has a long service life.

3. The rubber sealing ring can be located on the valve body or on the butterfly plate, which can be applied to the medium with different characteristics for users to choose.

4. The butterfly plate adopts a frame structure, which has high strength, large overflow area and small flow resistance.

5. The overall paint can effectively prevent corrosion, and as long as the sealing material of the sealing seat is replaced, it can be used in different media.

6. This valve has a two-way sealing function, which is not controlled by the flow direction of the medium during installation, nor is it affected by the spatial position, and can be installed in any direction.

7. This valve has a unique structure, flexible operation, labor-saving and convenient.

The following are some well-known brands recognized in China in the valve industry, which are widely recognized and enjoy 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, which is currently for reference only: Suzhou Neway Valve, Shanghai Guanlong Valve, Shanghai Qizhong Valve, Sanhua, Su Yan, Shentong, Su Valve, Nanfang, Jiang.

First, the word Yao. In general, the selection of valve manufacturers needs to be comprehensively considered according to actual needs, and choose manufacturers with a high technical level and good reputation for cooperation.

We need to note that the above manufacturers are only estimates and references, the specific situation may be due to changes in the market, the size of the competitive landscape, product quality stability and a series of factors and changes or floating at any time, valves as an indispensable key device in industrial production and civil facilities, the quality and reputation of its brand directly affect the satisfaction and trust of users.

1. The sealing surface is different.

The sealing surface of D71X-16 is a rubber seal, and the D71H-16 butterfly valve is a stainless steel seal.

2. The corrosion resistance is different.

D71X-16 can only pass the medium of general temperature and is not resistant to acid and alkali. D71H-16 butterfly valve is corrosion-resistant and friction-resistant, and can pass through acid, alkali or impurities.

3. The role is different.

D71X-16 is suitable for the temperature -23 socks coarse soft seal butterfly valve 200, nominal pressure of food, medicine, chemical, petroleum, electric power, metallurgy, urban construction, textile, papermaking, steel, water conservancy and other industries on the pipeline to regulate the flow and intercept the medium.

The D71H-16 butterfly valve is suitable for use in industrial pipelines that are resistant to acid friction.

The difference between D71X-16 and D71H-16 butterfly valves is that the cut-off is different, the latter is stainless steel seal, corrosion resistant and friction resistant, and can pass through acid, alkali or impurity medium fluid. The former is rubber sealed, which can only pass the medium of general temperature, and is not resistant to acid and alkali and can be asked Luoyang Guanning.

The complete model of D71X-16 should be D71X-16Z, Z means that the body material of the butterfly valve is gray cast iron, which can usually be ignored in the model representation, that is, D71X-16;

The C in D71X-16C represents that the body of the butterfly valve is made of carbon steel;

So the difference between D71X-16 and D71X-16C is that one is made of gray cast iron and the other is made of carbon steel.

DN100 means that the diameter of the butterfly valve is 100mm, which refers to the inner diameter;

A complete butterfly valve model needs the parameter information of caliber, drive mode, connection mode, structural form, sealing surface material, nominal pressure, and valve body material.
