Principles of selecting gate valves The gate valve should be the first choice when shut-off valves need to be used for pipelines. 1. Although gate valves are not restricted by the temperature as well as pressure, for gate valves with large nominal diameters and gate valves used under the medium and...

In the 1930s, the butterfly valve was invented in United States. It was introduced into Japan in the 1950s and was not widely used until the 1960s. The butterfly valve was promoted in China in the 1970s. At present, the butterfly valve with DN300 has gradually replaced...

The high temperature conditions here refer to the conditions when the medium temperatures are equal to or higher than the starting creep temperatures of the metallic materials. The creep temperature of carbon steel is about 400℃; chromium molybdenum alloy steel 450℃; austenitic...

The balls of floating ball valves are floating. Under the effects of the medium pressure, the ball can take a certain displacement and be pressed against the outlet side of the seal, to ensure that the outlet end is sealed and the seal is a single-side forced...

Although there is still a gap between China's valve industry and the international advanced level nowadays, China's valve industry has already gone through the simple copy and absorption period. Take globe valves as an example, manufacturers should look for...

China's valve industry is able to produce a dozen of products, such as gate valve, globe valve, ball valve, butterfly valve, safety valve, check valve, throttle valve, plug valve, reducing valve, diaphragm valve, drain valve, emergency cut-off valve, etc. These valves can be used in the highest...

Chinese control valves began from 1960s, and we could only produce 600 kinds of valves with 2700 specifications before 1980s. We lacked the ability of designing and manufacturing valves with high parameter and technology. In order to meet the requirement of high parameter and technology valves in the...

A small valve on the radiator can automatically keep the most comfortable temperature in your room all the time in winter. When the outdoor temperature rises one day, the boiler room can automatically adjust extracting water temperature to prevent unnecessary waste of thermal energy. Some residents...

From global financial crisis a few years ago to later upturn, and the economic rise up now, economic changes also cause the different growth for forged steel ball valves in valve industry. Why can common forged steel ball valves make traditional valve industry innovate?   The reason of forged steel...

A report shows that since 2012, localization of high-end valves has been quite difficult in China. At present, basic parts have already become a bottleneck which limits Chinese valve industry to develop into high-end. The support for basic parts of high-end equipment needs to be enhanced further. ...
