Cast steel Ball valve refers to a floating ball valve with a cast steel valve body. These valves are primarily designed for low-pressure service with a flexible temperature range. usually equipped with flanged end connections，manual operation (lever or gear) is adopted. Due to the low pressure level and small size, the torque to open or close the valve is not large, so  Generally speaking, Cast Steel Floating Ball Valve is mainly used for switching applications and smaller throttling purposes.
