The FCV flow control valve is a device installed in fluid transport processes, specifically designed for the quantitative feeding or on/off control of pneumatic conveying of powdered bulk materials. It can be used for all fluidized bulk materials, as well as for high-temperature and corrosive materials. Primarily, it serves an on/off flow regulation function in flow control systems for powders, crystalline materials, and small granular materials. It is typically used in series with shut-off valves. Suitable for controlling the discharge of powdered materials, such as raw meal, cement, and other powdered material storage bins, discharge hoppers, self-unloading ships, and other discharge control applications. Widely used in industries such as cement, coal, steel, power plants, and fertilizers.
