Single acting pneumatic ball valve feature
Single acting pneumatic ball valve is a kind of quarter-turn on-off valve is used for quick open and close in the emergency system.Single acting pneumatic ball valve is mainly used for shut-off control of media. This series of Single acting pneumatic 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, Single acting pneumatic 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, Single acting pneumatic 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.
