Why are Ball Valves Frequently Used in Various Fields?

In the 1950s, ball valves gradually appeared in the industrial production of western developed countries. Moreover, they are used more frequently, and their performances have been continuously improved. Nowadays, in China, ball valves are mainly used in pharmaceutical machinery, petroleum refining, water conservancy and chemical industry, electric power and other industries, which all play a very important role in the national economy. Therefore, ball valves are also indispensable in these industries.

How do ball valves stand out?

There are many kinds of valves, and the reason why ball valves can stand out and be used frequently in various applications is inseparable from their irreplaceable advantages. So, what are the advantages of ball valves?

First of all, anti-friction is the non-negligible advantage of ball valves.  According to the technical personnel in the industry, for valves, wear resistance is an important factor to test the quality of valves. The O-ring material of ball valves is alloy steel surfacing, while O-rings of general valves are made by rubber or other metals, the wear resistance of which is no better than that of alloy steel surfacing.

"Everyone knows that the valve is a switch, which needs to be opened and closed, so that the sealing ring will be greatly worn. However, that will not happen to the sealing ring of the ball valve." The industry said so.

Secondly, the sealing performance of the ball valve is extremely good. It is understood that the seal of ball valves is not made by grinding machines but by grinders, which can ensure a higher degree of coincidence. Thus, the sealing performance is very reliable.

In addition, ball valves have long service life, which is also a point that manufacturers pay great attention to related production facilities.

"Because the ball valve is often used in major industries, if its life is not long enough and it is often replaced, this is very troublesome and will cause many mistakes."
