Ball Valves SE
What is a Ball Valve SE?
A Ball Valve SE (Screwed End) is a quarter-turn valve designed to start, stop, and regulate fluid flow by rotating a perforated ball inside the valve body. When the hole in the ball aligns with the pipeline, flow passes freely; when rotated 90°, the flow is blocked.
Ball Valve SEs are widely utilized in water supply, oil and gas pipelines, steam networks, and chemical processing systems due to their compact structure, quick quarter-turn operation, and reliable sealing properties. Designed to handle high pressure and temperature variations, these valves ensure smooth flow control and long service life. Asaid Steel Industries stands as a trusted manufacturer and supplier of Ball Valve SE, offering robust, precision-engineered, and corrosion-resistant valves that meet international quality standards. With a strong focus on durability, safety, and performance, we provide solutions tailored for both industrial and commercial applications.
