A detailed explanation of the "why" behind the hidden aspects of the FAQ. Clearly introducing examples of failures and tips for correct operation!
We have compiled an introductory guide to ball valves themed "Behind the FAQ" for those who are handling valves for the first time or feel that the FAQ alone is difficult to understand. This document clearly explains points of misunderstanding and reasons for issues that are not covered in the FAQ, based on common failure cases that have occurred on-site. By understanding the background such as "Why are there so many questions?" and "Where are operational errors likely to occur?", you can achieve safer and more reliable operations. The structure is easy to read even for beginners, and it contains tips for usage that can be grasped in a short time, making it immediately applicable on-site.
