What size screw is equipped with the butterfly valve DN80? begging

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, 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.

Different models, different pressure levels, different sealing materials, the same DN80 caliber, but their clamp bolt diameters are very different, I can only provide the common one, the clamp bolt hole is 18mm in diameter

Generally, double-ended studs, D371X type clamping butterfly valves, studs are 12-m20*180-200, studs are 12-m24*200-220, and their length is related to the thickness of the clamping flange, and the bolts used in different models and products of different manufacturers are not the same. This can be found in valve manuals or product brochures.

DN250 can be used with PN10 or PN16 stud bolts and hexagonal bolts, the total length of the stud bolts is 185, the length of the hexagonal bolts is not to mention, the diameter is M16*60 or M24*60

Generally, double-ended studs, D371X type clamping butterfly valves, studs are 12-m20*180-200, studs are 12-m24*200-220, and their length is related to the thickness of the clamping flange, and the bolts used in different models and products of different manufacturers are not the same.

Summary. Butterfly valve, also known as flap valve, is a simple structure of the regulating valve, which can be used for the on/off control of low-pressure pipeline medium, and the butterfly valve refers to a kind of valve that is rotated around the valve shaft to open and close the closing part (disc or butterfly plate) as a disc. 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.

It mainly plays the role of cutting and throttling on the pipeline. The butterfly valve opening and closing part is a disc-shaped butterfly plate, which rotates around its own axis in the valve body, so as to achieve the purpose of opening and closing or adjusting.

Hello, we are glad to answer for you DN80 butterfly valve flange has four holes for low pressure and eight holes for high pressure point.

Thank you. Air conditioner for water.

Be clear in detail.

If it is used on the top of the butterfly valve, it is recommended that you can only use the thread diameter and screw length upstairs as soon as possible, and it is best that you touch the thickness of the valve and the thickness of the 2 flanges and the thickness of the two-end nut
