In the past 40 years of technological development, the ball valve has been continuously improved and updated in its production technology and product structure. It is a new type of valve that is gradually being widely used. In West countries with developed industries, the ball valves are increasingly used year by year. Ball valves play an extremely important role in oil and gas pipelines, devices of oil extraction, oil refining, petrochemical, chemical, chemical fiber, metallurgy, electric power, nuclear power, food and paper. Products of Baltic ball valve mainly include top entry ball valves, metal seated ball valves, and fully welded ball valves.

The ball valve is composed of an actuator, a valve body, a spring, a valve core, a stem. The ball valve is mainly used to cut, distribute and change the flow direction of the medium in the pipeline. The valve core is a sphere with a cavity, and is controlled by the valve stem to rotate 90 degrees so as to make the valve unblocked or blocked. The ball valve is not limited by the mounting direction, so the medium can flow arbitrarily. The fluid resistance is small, so the full-bore ball valve almost gets little flow resistance. The sealing surface of the ball valve is usually being closed with the sphere, so it is not easily eroded by the medium. The operation is not only convenient, but the structure is also simple and compact. The ball valve can be used under the working conditions of water, natural gas, acid, or solvent.

Here are Some Features of the Ball Valve: 

1.Strong airtightness. It is necessary to completely match the inner valve core with the sealing ring to open the valve, so the ball valve has relatively strong airtightness.

2.Anti-blow out Stem. The stem inside the ball valve has the characteristics of anti-explosion, so that the dangerous accidents can be moderately reduced.

3. Fire safe and anti-static device. There is a spring among the ball, the stem and the valve body, thus the ball valve can discharge the static electricity generated by the switching process.

4. High Service Life. The valve ball can completely enclose the valve seat when the all-welded ball valve is opened, so the impurities in the medium will not be flushed to the valve seat or the packing surface of valve body. Hence, the valve body has a same service life as the pipeline due to his special construction.

Now, more and more brands and categories of ball valves with uneven quality appear in the market. As a new buyer, how can we identify the ball valves?

Firstly, you can watch the appearance of the ball valve to see if there are bubbles, burrs and other flaws outside. Whether there is the feeling of stinging when touching it, and then see whether the inside of the valve is clean, whether there is sand hole. You can also measure the thickness of the valve to see whether it meets the national standards in order to prevent some manufacturers from doing shoddy work and using inferior material, failing the quality of ball valves.

Secondly, we should see whether the manufacturer has advanced equipment and high-quality technical guidance. If necessary, we can also test the material of the ball valve to see if it is qualified, so as to prevent some manufacturers from bad behaviors and result in material failure or even rust; And we can also check the valve core which is an important part of the valve, it can be said that the valve core directly determines the performance of the ball valve and the length of the service life. High-quality ball valves are usually made of high-hardness, high-wear metal materials, and have very strict requirements on machining accuracy to ensure that the ball valve can work stably under high pressure.

Finally, as a qualified ball valve, its requirements for the smoothness, roundness and concentricity of the valve body are extremely high; the oil seal groove should be smooth and moderately round.

Valves are the most widely used products in various industries. Due to the increasing demand and the large market development space, valve manufacturers are constantly emerging. As the market becomes active, competition becomes intensifying. With the change of marketing methods, the international market gradually entered China with largest valve production, leaving major challenges to Chinese valve enterprises. China's valves started late and the technology level is relatively backward. Some high-tech valves can only rely on imports, and it is difficult to break through the threshold, which also becomes the main reason for the expansion of its volume. Therefore, it is necessary to strengthen the research and development capabilities of technology. Only high-tech valve products can break through the barriers and remain stable in the Chinese valve market, even the international markets.

With a wide variety of ball valves, Baltic Valves, well equipped, have complete processing and testing methods, and strict manufacturing control, which is a competitive choice. (Editor: Megan Jeawin)
