What is the leak rate of a high performance butterfly valve?

There is a leakage rate of 1% for hard seals and 0% leakage rate for soft seals.

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.

You can choose other valves. It can reach 0 leaks.

The general experimental standard of butterfly valve is API598, and the leakage is divided into soft seal and hard seal to distinguish, and other leakage standards such as BS6364, etc., which require zero leakage at room temperature for soft sealed valves, that is, there are no visible bubbles or droplets, and the leakage of metal hard seal butterfly valve is more, and some are divided into several levels of leakage, the most stringent requirement is zero leakage, and the lightest one requires no pump inspection.

Specifically, you can choose according to the actual working conditions, because the butterfly valve with different requirements is different, and the design and production requirements of the valve are also different under different working conditions.

Since it is high-performance, it can do zero leakage ** problem.

The leakage of the valve is calculated according to the sealing level and nominal diameter, and the volume of leaked liquid or the number of bubbles formed by the gas according to the experimental specifications.

The leakage of the valve is a difficult indicator to calculate, unless there is a very accurate flow balance system to complete the theoretical calculation, so in practical applications are used to estimate. If the valve is relatively new and is a well-known brand product, it is negligible. If it is not a good quality product, it can be selected according to the rated flow value of 1-5%, and at the same time, it is necessary to take into account the actual use conditions, and if the working environment is not good, it can be appropriately taken a larger value.
