The difference between clamp butterfly valve manufacturers and flanged butterfly valves is recommend

Here are some 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, Chaoda, 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.

This problem mainly refers to the two forms of butterfly valves, the clamp type and the flange type

The clamp-type butterfly valve (the valve itself cannot be flanged) is to connect the valve between the two pipe flanges with a stud bolt; The clamp-on butterfly valve has a simple structure, small size and light weight, and is composed of only a few parts. Moreover, it can be opened and closed quickly by only 90° rotation, which is easy to operate, and the valve has good fluid control characteristics. The picture above below is the manual butterfly valve, and the picture below is the electric butterfly valve

<> flanged butterfly valve is a valve with a flange, and the upper two ends of the valve are connected to the pipe flange with bolts. The sealing surface is wear-resistant and has a long service life. The structure is unique, the operation is flexible, labor-saving, convenient, and not affected by the high and low pressure of the medium.

The picture below shows the manual flanged butterfly valve, and the following picture shows the electric flanged butterfly valve

<>, the specifications of the clamp type and the flange type are the same, but the flange bolts of the clamp butterfly valve are relatively long, and the length is "2 times the flange thickness + valve thickness + 2 nuts thickness", and the clamp valve itself cannot be flanged; As long as the bolts and nuts are disassembled, then the pipes at both ends of the valve will not work properly.

The bolt of the flange type is relatively short, and the length is "2 times the thickness of the flange + 2 nuts", that is, the flange of the valve body and the flange on the pipeline are paired, connected by bolts, and the nut is locked; When the flange bolt nut at one end is removed, it does not affect the normal operation of the pipe at the other end.
