The fixed ball valve is suitable for long distance pipelines and general industrial pipelines. Compared with the floating ball valve, the force generated by the medium pressure during work is transferred to the upper and lower bearings, the ball does not move, the seal of the valve is achieved by the spring and the medium pressure to push the valve seat, the operating torque is small, the sealing performance is reliable, and the life is long.
Mainly used in petroleum, chemical, pharmaceutical and other working conditions of pipeline, cut off or connect water, oil, steam and other pipeline media.
