Favorable factors (1) The "13th Five-Year" nuclear industry development plan stimulating the market demand for nuclear valves Nuclear power is recognized as the clean energy. With the development of nuclear power technology as well as its enhanced security and economy, the nuclear...

High-temperature Grade III When working temperatures of valves are between 650℃ and 730℃, the valves are called the high-temperature Grade III valves, also named the high-temperature PIII Grade valves. They are mainly used for the heavy oil catalytic cracking units of refineries. The main material of...

High Temperature Working Conditions Valves used for the high temperature working conditions mainly refer to the high temperature valves applied to the refineries.   Sub-high Temperature Sub-high temperatures refer to the working temperatures of valves between 325℃ and 425℃. When the medium...

There are many types of globe valves' clacks such as the flat plate type, the plug type, the cone (needle) type, the ball type, etc. Characteristics and selection principles of globe valves with various clacks are different, and today we mainly introduce the above four clack types...

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...
