A natural gas forged steel buried double blow-off ball valve is a valve unit used for natural gas pipeline control, featuring core characteristics including:

Structural characteristics

Forged steel material is used, with the valve body and stem integrated into a single unit via welding, effectively preventing external leakage. The valve is equipped with dual venting units, which, through vent pipes and valves, facilitate the release of pipeline pressure for easy maintenance and inspection.

Function and Usage

Suited for urban gas, natural gas transmission pipelines, and centralized heating systems, it allows for rapid opening and closing operations while reducing pipeline maintenance risks. The buried design minimizes the need for valve pit construction, saving on construction costs and time.

Material and Sealing

The valve seat features a carbon fiber reinforced Teflon sealing ring and a disc spring structure, adapting to pressure and temperature changes to ensure sealing performance. The venting unit design allows for adjustable venting port direction, facilitating medium discharge control.
