The number unit of gate valve and what are the specifications of gate valve

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.

The unit of number of gate valves is units. A few valves. However, it is also possible to use the word "individual".

The correct should be a few valves, and the valve standard is strictly speaking.

Meaning of gate valve model: Gate valve is one of the more common types of shut-off valves, which is generally suitable for fully open or fully closed two-position operation control, mainly used to close the medium in the pipeline, and is usually called a shut-off valve or a blocking valve. With the growth of valve demand and the expansion of demand in the machinery industry, gate valves have become an indispensable part of modern industrial control systems.

For more and more complex working conditions and harsh use requirements, the correct selection of gate valve models is related to the adaptability of pipeline media and an important guarantee for the safety of working conditions.

Gate valve model compilation representation method:

Additional code for gate valve: WZ stands for bellows gate valve, DZ cryogenic gate valve, NKZ vacuum gate valve, PZ knife gate valve;

Gate valve type indication: z;

Drive mode indication: manual without code (according to the regulations usually omitted electro-hydraulic, 3 turbine worm, 5-bevel gear transmission, 6 pneumatic, 9-electric;

Connection mode: 4 flange connection, 6 welding, 7 pairs of clamp type; The structural form is indicated: 0 elastic ram, 1 open rod mode single ram, 2-open rod mode double ram, 3-open rod parallel single ram, 4-open rod parallel double ram, 5 solid rod mode single ram, 6 dark rod wedge double ram, 7 dark rod parallel single ram, 9 dark rod parallel double ram;

There are many domestic manufacturers of gate valves.

Rigid single gate gate valve.

The size of the joints is also mostly not uniform. It is mainly divided into the following categories: JB T2203 1999 "Gate Valve Structure Length" as the main general class. At present, most domestic safety valve manufacturers are designed and produced according to this standard.

The working principle of manual gate valve: turn the handwheel, through the thread of the handwheel and the valve stem, lift or lower the valve plate connected with the valve stem, and achieve the effect of opening and closing.

According to the classification of the main material of the shell, the gate valve can be divided into:

Metal material valves: such as carbon steel valves, alloy steel valves, stainless steel valves, cast iron valves, titanium alloy valves, Monel valves, copper alloy valves, lead alloy valves, etc.

Metal body lining valves: such as rubber lining valves, fluorine lining valves, lead lining valves, plastic lining valves, enamel lining valves.

Non-metallic material valves: such as ceramic valves, glass valves, plastic valves.
