There are many kinds of valves, why are ball valves frequently used in various fields?

In 1950s, ball valves gradually appeared in industrial production in developed countries.And its usage rate is getting higher year by year, and it has been continuously improved by people in various properties.Nowadays, ball valves are mainly used in pharmaceuticals, petroleum refining, water conservancy, chemical industry, power, municipal paper and steel industries in China. These industries play a very important role in the national economy. Therefore, ball valves are also indispensable equipment in these industries.

How does a ball valve stand out?

In the field of valves, there are many valves. The reason why ball valves stand out and are frequently used in various fields is inevitably due to their irreplaceable advantages.So what are the advantages of ball valves?

First of all, the unimportant advantage of ball valves is wear resistance.According to the technicians in the industry, wear resistance is an important factor in checking the quality of valves. The sealing ring material of ball valves is alloy steel surfacing, while the general sealing ring of valves is rubber or other metal. These materials have no good wear resistance of alloy steel surfacing of ball valves."It is well known that a valve is a switch which requires opening and closing, and that the sealing ring is subject to considerable wear while opening and closing, but this is not the case with the sealing ring of the ball valve."That's what the industry says.Secondly, the sealing performance of the ball valve is very good.It is understood that the sealing of ball valves is not made by machine grinding, but by manual grinding to ensure a higher degree of conformity, so the sealing performance is very reliable.In addition, ball valves have a very long service life.This is also a point that manufacturers pay great attention to the relevant production equipment."Because it is often used in all important frontline industries, if it is not long enough to be replaced frequently, it will become very troublesome and will cause a lot of errors."

Ball Valve Selection Skills Share

As an opening and closing part by means of valve stem, the stable performance of ball valve equipment is very important.Therefore, some details need to be followed in the selection to better meet the actual needs.Focus on size selection.It is understood that the flow resistance of ball valves is generally very small and the passages and pipes are almost the same, so they can be used in areas that are sensitive to media conditions.When choosing such valves, attention should be paid to the selection of dimensions, which vary in weight and effect.Consider price appropriately.When choosing valves, in addition to ratios of goods, consideration should also be given to economy. As long as the actual needs can be met, it is not necessary to choose a large size or weight is the best choice.In addition, fixed ball valves are all closed cavities. If they are used in cryogenic media or in environments where gasification may occur, a valve with a drain device must be selected.Change ball valve to butterfly valve or globe valve if necessary.It is pointed out in the industry that in general this type of valve is suitable for pipe disconnection with ball pass requirements.Selection of such valves, if necessary, can be tailored to the needs of the channel structure to ensure that the needs of multiple channels are met and the number of valves used is minimized.It is worth noting that brand and price screening are also important for ball valve selection, and it is advisable to select valves with a high price ratio.
