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.

ST Steam Tracing 3 4 indicates the connection caliber.

DN20 usually refers to a six-point character.

First of all, 3 4 is the meaning of DN20, and DU Q11F-160P is the stainless steel inner screw Zhi pattern ball valve. dao

Q valve code: ball valve.

Manual non-code indication version.

1 form of connection:

Right internal thread. 1. Structural form: floating straight-through.

f Sealing material: fluoroplastic.

160 valve pressure: 16MPa

P body material: stainless steel.

160kg valve P stands for stainless steel 304 material, please call me Lei Feng, Q is the ball valve, 1 is the thread 1 is the connection form, F is the sealed PTFE, 3 4 is the caliber.

This is the inch pipe thread, and its value refers to.

The bore diameter of the tube or ball valve (now approximate).

That is, how much inner diameter of the water pipe is threaded. It's a conventional way of representation.

The actual size of the thread must be checked in the table. However, the higher the value, the larger the thread outer diameter.

This is the nominal diameter of the pipe or ball valve in inches.

It is a representation of the pipe diameter in the inch thread, which can be referred to.

Here 4 refers to inches, 1 inch = 8 points, then there is 1 2 corresponds to 4 points, 1 4 corresponds to 2 points, 3 4 corresponds to 6 points.

The conversion of inches to the metric system is: 1 inch = millimeter, and the diameter of the steel pipe is rounded, such as 1 2 corresponds to DN15, 1 4 corresponds to DN10, 3 4 corresponds to DN20, 1 inch corresponds to DN25, and the number here does not represent the inner diameter or outer diameter.

That's right. The three-piece thread button ball valve, commonly known as the Cantonese ball valve, was first invented by Guangdong Mingzhu. The ball valves produced by the company are all one-piece or two-piece type, and the 304 stainless steel wire button ball valve is mainly a one-piece type.

Stainless steel wire button ball valve 1 4 is DN8 8 mm.

OK. It is recommended to choose a valve with the appropriate temperature range, and pay attention to the safety precautions when operating the valve.

No problem, but it depends on the temperature.

Thread buckle is a folk name, and the correct name is thread.

That's right, it's the same thing as a wire ball valve.
