Sulfuric acid regulating valves are designed for the sulfuric acid industry to meet the challenges of various operating conditions. It not only has excellent corrosion resistance, but also shows excellent adjustment ability. The regulating valve is suitable for several process stages including drying, primary absorption, secondary absorption, waste heat recovery, as well as waste heat boiler feed water and steam regulation position. Its corrosion resistance is due to the use of special alloy materials, while high-strength engineering materials are used in the sealing part. Through the unique low-friction maze packing design, there is no risk of leakage, and no vibration and noise during operation to ensure the stability and reliability of the equipment. In addition, it also has the characteristics of high adjustment accuracy and long service life.
