  • Pneumatic cut off ball valve feature

    Pneumatic cut off ball valve is a kind of quarter-turn on-off valve.Pneumatic cut off ball valve is mainly used for shut-off control of media. This series of Pneumatic cut off ball valve  adopts round hole in the ball. When opened, it is directly connected to the body flow channel, featured by high flow capacity. Compared with plunger valves, Pneumatic cut off ball valve has small structural sizes, light weight and the function of self-cleaning between plug and seat. Therefore, it is very suitable for viscous, fibrous media and those containing suspended solid particles. With low heat expansion impact due to temperature, and good sealing performance, Pneumatic cut off ball valve is widely applied in the systems of such industries as petrochemical industry, metallurgy, chemical fiber, pulp & paper, medicine, hydroelectric station, etc. to meet the needs of remote control of process parameters such as flow, pressure, temperature and liquid level of all gases, liquids or corrosive gases and liquid media.
