The O-type shut-off Ball Valve is a quarter-turn on-off valve, primarily used for controlling the flow of media. This series of ball valves features a round hole in the ball, which allows direct connection to the body's flow channel when open, 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. This makes it particularly suitable for viscous, fibrous media, and media containing suspended solid particles. With low thermal expansion impact due to temperature changes and excellent sealing performance, it is widely applied in industries such as petrochemicals, metallurgy, chemical fiber, pulp and paper, medicine, and hydroelectric stations. It meets the needs of remote control for process parameters like flow, pressure, temperature, and liquid level for all types of gases, liquids, or corrosive media.
