The O-type shut-off Ball Valve is a quarter-turn on-off valve primarily used for the control of media flow. This series of ball valves features a round hole in the ball, which allows direct connection to the body's flow channel when opened, offering high flow capacity. Compared to plug valves, it has a smaller structural size, lighter weight, and self-cleaning functionality between the plug and seat. Therefore, it is particularly suitable for viscous, fibrous media, and media containing suspended solid particles. It also exhibits low thermal expansion impact due to temperature changes and provides excellent sealing performance. These valves are widely applied in industries such as petrochemical, metallurgy, chemical fiber, pulp and paper, pharmaceuticals, and hydroelectric stations, meeting the needs of remote control for process parameters like flow, pressure, temperature, and liquid level of various gases, liquids, or corrosive media.
