The ball valve was introduced in 1950s. With the rapid development of science and technology, the production process and the continuous improvement of the product structure, in a short period of 40 years, it has rapidly developed into a major type of valve. Nowadays, manufacturers use stainless steel and other similar materials to produce sanitary valves used in many industries, such as chemical, medical and food industries. However, one topic which cannot be ignored is the comparison between ball and gate valves, because the two are both widely applied. This passage analyses the advantages of ball valves and gate valves.

3. Which is better, a ball valve or a gate valve?
1. Advantages of ball valves
Wear-resistant. Ball valves'sealing ring is made of stainless steel surfacing, so the hard-sealed ball valve will not produce too much wear when it is switched on and off.
Great sealing performance. Because of the sealing of the hard-sealed ball valve is manually ground, it can be used until the valve core and the sealing ring are completely matched. Therefore, its sealing performance is reliable.
Light switch. Since ball valve adopts a spring to make the sealing ring and the valve core tightly hug together, the switch is very light when the external force exceeds the pre-tightening force of the spring.
Long service life. The pneumatic ball valve has a simple and compact structure, reliable sealing, and convenient maintenance. The sealing surface and the spherical surface are often in a closed state, which is not easy to be eroded by the medium. It is easy to operate and maintain. It is suitable for general working media such as water, solvent, acid and natural gas, and is mainly used for cutting off. Or connect the medium in the pipeline, and can also be used for fluid adjustment and control.
2. Advantages of gate valves
After the gate valve is opened, the internal medium channel of the valve body is straight without any obstruction, and the flow resistance is very small.
When opening and closing, the movement direction of the gate valve is perpendicular to the flow direction of the medium, the pressure is small, and the opening and closing is labor-saving.
The height of the gate valve is large, so the opening and closing time is longer, and it is not prone to water hammer.
The two sides of the gate valve channel are symmetrical, and the medium can flow in any direction on both sides, so the installation of the gate valve is very convenient.
The structure length is short, the manufacturing process is good, and the application range is wide.
3. Which is better, a ball valve or a gate valve?
The range of applications of ball valves and gate valves is different, so it is not possible to directly compare which of them is better. However, from a practical point of view, the ball valve has an anti-static function. In addition to this, the ball valve has a simple and compact structure and a more reliable seal.
