Because of the particularity of its medium, a few abnormalities of gas welded ball valves are likely to cause leakage problem. Needless to say, the consequence for the gas leak is really severe. So when buying gas welded ball valves, you’d better learn some knowledge about its characteristics so that the quality of the valves can be guaranteed.

Composed of carbonized Teflon seal ring and disc spring, the seat of gas welded ball valves has a good ability to adapt to the temperature and pressure. Generally, as long as the temperature and pressure don't exceed the marked ones, it is not prone to emerge any leakage problem. Also, in the sphere processing, there is an advanced computer monitor to monitor the completion status so as to ensure the precision. Because the material of valve body is same with pipe, so it will be not easy to have these following problems: unbalanced stress, road deformation and so on.

For the sealing ring of gas welded ball valves, it uses RPTFE material with a content of about 25% carbon to ensure zero leakage. For buried welded ball valves, instead of building a tall valve well, they can be directly buried in the ground simply with a small shallow well set up on the ground to meet their requirements, so this can greatly save construction financing and engineering time. Compared with other valves, gas welded ball valves have small volume, beautiful appearance, as well as long service life for at least 15 years in the case of normal operation.

Gas welded ball valves should not only be durable but also have good sealing performance. Learning some knowledge about its characteristics can help you to buy high-quality valves and eliminate the security threaten.
