What are the best imported brands of cryogenic valves?

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.

Personally, I think the following are some of the more well-known and influential valve brand manufacturers in the market than Jianxiao, but for reference only: Suzhou Neway Valve, Shanghai Guanlong Valve, Shanghai Qizhong Valve, Sanhua, Chaoda, Shentong, Su Valve, Nanfang, Jiang.

First, the word Yao. It should be noted that 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's top consumption, the size of the competition pattern, and the stability of the product quality and bridge content.

Cryogenic valves include cryogenic ball valves, cryogenic gate valves, cryogenic globe valves, cryogenic safety valves, cryogenic check valves, cryogenic butterfly valves, cryogenic needle valves, cryogenic throttle valves, cryogenic pressure reducing valves, etc., which are mainly used in ethylene, liquefied natural gas devices, natural gas LPG LNG storage tanks, receiving bases and satellite stations, air separation equipment, petrochemical tail gas separation equipment, liquid oxygen, liquid nitrogen, liquid argon, carbon dioxide cryogenic storage tanks and tankers, pressure swing adsorption oxygen production and other devices. The output liquid low-temperature medium such as ethylene, liquid oxygen, liquid hydrogen, liquefied natural gas, liquefied petroleum products, etc., is not only flammable and explosive, but also gasifies when the temperature rises, and the volume expands hundreds of times when gasified.

The material of the LNG valve is very important, and the unqualified material will cause external or internal leakage of the shell and sealing surface; The comprehensive mechanical properties, strength and stiffness of the parts cannot meet the requirements of use and even break. Caused by leakage of LNG media**. Therefore, in the process of developing, designing and developing LNG valves, the material is the primary and key issue.

Hello, Shanghai Guardian valve is the best quality.

After years of manufacturing, it has accumulated rich experience, from design, technology to manufacturing is becoming more and more mature, and has developed a series of cryogenic valves.

There are very few that can be done well, and I want to buy imported ones if I don't change them for ten years, and I use Kester's, the temperature is -75 degrees, and it's OK.
