How do ball valve products of different diameters perform in terms of air tightness and opening/closing function after long-term storage without pre filling with air?

Video: https://youtube.com/shorts/wd4A-TGWrFA

The valves, which had been idle in storage for an extended period without pre-inflation, were activated to showcase their core functions. At the 

exact moment of opening, the air sealed inside the valves was rapidly released, producing a distinct and audible airflow sound—an intuitive

 indicator of both smooth on-off operation and airtight integrity.​

Conclusion
Through real warehouse scenario tests and intuitive functional demonstrations, the video fully verifies that the series of multi-caliber ball valves still maintain stable and excellent air tightness after long-term storage. Meanwhile, the valves feature sensitive on-off actions and reliable sealing effects, complying with relevant sealing performance requirements.
