In high-risk process industries such as petroleum, chemical, and natural gas, before inspecting, maintaining, or replacing pipelines or equipment, it is essential to ensure complete isolation of the internal media to prevent accidental leakage of toxic, f
Cast steel fixed hard seal ball valves, with their superior structural strength, sealing performance, and durability, become the "guardians" of critical pipelines—like a fearless warrior, they overcome obstacles in extreme environments to ensure the safe,
In industrial fluid control systems, ball valves are widely used due to their advantages such as rapid opening and closing, low flow resistance, and ease of operation. Among them, the SBB single ball valve, with its high reliability and sealing stability,
In high-risk industrial sectors such as oil, natural gas, chemicals, and power, the reliability of fluid control systems directly impacts personnel safety, environmental protection, and production continuity.
The ball has no fixed support shaft and is connected to the valve body only through the upper and lower valve stems, which simplifies the overall structure and reduces the number of parts.
The SBB single ball valve, a specialized valve integrating shut-off and venting functions, exhibits excellent sealing performance under medium and low pressure conditions thanks to its unique single-ball design, particularly excelling in reducing internal
