FLOWSERVE black water regulating valve is mainly used to regulate the flow rate of quenching chamber, carbon washing tower, flash steam tank and other equipment in coal chemical system. The common features of the working conditions are: large pressure difference, high temperature, strong corrosion, medium containing solid particles, easy to flash vapor corrosion. The damage of medium to valve is mainly manifested as: the erosion damage of high speed fluid and solid particles to the inner wall and internal parts of valve and the damage of medium electric and chemical corrosion. Compared with the general control valves, the foss black water control valves have higher corrosion resistance and erosion resistance, and the later maintenance is very convenient.
