The ball valve features an advanced floating ball design, where the stem rotates $90^\circ$ to drive the ball for seamless opening and closing operations. When the valve is fully closed, the line pressure presses the floating ball firmly against the downstream body seat, achieving an exceptional self-sealing performance. Its primary characteristics include a highly compact structural profile, reliable sealing integrity, mechanical simplicity, and effortless maintenance. The sealing faces and the spherical surface remain closely mated during operation, effectively protecting them from medium erosion and scoring. It is easy to operate and service, making it highly versatile for handling water, steam, and natural gas, as well as harsher working conditions where the medium contains suspended particulate matter. It performs reliably within pipeline systems for both tight isolation and coarse medium regulation.
