The American standard ball valve is engineered for precise flow control, distribution, and redirection in pipeline systems. Featuring a rotating spherical closure mechanism, these valves deliver superior efficiency and reliability compared to traditional gate valves. Available in two-piece and three-piece designs, they are typically installed horizontally and serve diverse industrial applications.
The floating ball design utilizes medium pressure to press the ball against sealing surfaces, ensuring tight closure. This configuration offers straightforward operation, exceptional sealing performance, and optimal performance in medium to low-pressure environments.
Fixed ball valves maintain stationary positioning under pressure while the valve seat adjusts to maintain secure sealing. Equipped with bearing systems to minimize operating torque, these valves excel in high-pressure applications and large-diameter pipeline systems.
Elastic ball valves combine flexible ball components with metal sealing elements, engineered specifically for demanding high-temperature and high-pressure conditions. External force application ensures reliable sealing performance when medium pressure alone is insufficient.
