What is the standard for the structural length of socket welded valves?

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.

Looking at the standard system, the American Standard is and.

The common structural length of socket welded valves in the market is the American standard.

It can be in accordance with the manufacturer's standards.

Overview of globe valve: The opening and closing parts of the globe valve are plug-shaped discs, the sealing surface is flat or conical, and the disc moves in a straight line along the center line of the fluid. The movement form of the valve stem has a lifting rod type (the valve stem is lifted, and the handwheel is not lifted), and there is also a lifting and rotating rod type (the handwheel and the valve stem rotate and lift together, and the nut is located on the valve body).

The shut-off valve is only suitable for full open and full closing, and is not allowed to be adjusted and throttled.

1) The globe valve has the following advantages:

1. The structure is simple, and the manufacturing and maintenance are relatively convenient.

2. The working stroke is small and the opening and closing time is short.

3. Good sealing, small friction between sealing surfaces, and long service life.

2) Attention should be paid to the following matters in the installation and maintenance of the globe valve:

1. The stop valve operated by the handwheel and handle can be installed in any position of the pipeline.

2. Hand wheels, handles and transmission mechanisms are not allowed to be used for lifting.

3. The flow direction of the medium should be consistent with the direction of the arrow shown on the valve body.
