What is the difference between valve heavy duty and medium valve, valve light and heavy duty

16 kg, 25 kg medium size is fine, 40 kg and above you have to use heavy duty. Heavy-duty body thickness.

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.

Valve is a device used to control the direction, pressure, and flow of fluid in a fluid system, and is a device that makes the medium (liquid, gas, powder) in the piping and equipment flow or stops and can control its flow.

The valve is a control component in the pipeline fluid transportation system, which is used to change the channel section and the direction of medium flow, and has the functions of diversion, cut-off, throttling, check, diversion or overflow pressure relief. Valves for fluid control range from the simplest shut-off valves to a wide variety of valves used in the most complex automation systems.

Heavy duty and light refer to the quality and weight of the valve, and the difference between the three is mostly reflected in the weight, material standard and thickness.

The heavy-duty valve body is thicker, which is designed according to the national standard valve body wall thickness, while the light-duty one is thinner, because the proportion of the valve body is the same, so the weight of the heavy-duty material is relatively heavier.

This kind of light weight should now be in Wenzhou, which means that it does not meet the national standard. Wall thickness. And the heavy has already been reached.

Now there are actually with and without materials. Hehe. There are so many variety.

However, this is also applicable to low-pressure valves

The dimensions are exactly the same, and they all meet the requirements of use.

Difference: The wall thickness is different.

It should refer to the weight of the valve, right? Isn't it.

Mainly divided by caliber.

Different valves are different in size, the caliber of the globe valve is not large, and the gate valve is generally within DN2000.

The largest ball valve is also within DN1500, and what can be done in China is generally within DN1200.

According to the nominal diameter of the valve, it can be divided into:

Small diameter valve: valve with nominal diameter DN<40mm.

Medium diameter valve: nominal diameter DN50 300mm valve.

Large-diameter valves: valves with nominal diameter DN350 1200mm.

Extra-large diameter valves: valves with nominal diameter DN 1400mm, e.g. hydropower industry: butterfly valves (ball valves).

Small diameter valve: nominal diameter DN<2000mm (1000) valve.

Medium diameter valve: nominal diameter DN2000 3500mm (1000-1800) valve.

Large diameter valve: nominal diameter DN3500 5000mm (1800-2500) valve.

Extra-large diameter valve: valve with nominal diameter DN 5000mm (2500).
