In chemical and environmental industries, the transportation of corrosive gases such as chlorine and sulfur dioxide is common. Conventional valves often fail in such environments due to poor corrosion resistance, leading to leakage, wear, and even safety accidents. Blow-through rotary valves, however, effectively address this challenge through proper material selection.

Most blow-through rotary valves are manufactured from SUS304 or SUS316 stainless steel. These materials not only provide excellent corrosion resistance but also withstand humid and acidic or alkaline gas environments. Over long-term operation, they minimize the risk of valve body corrosion, ensuring safe and stable gas transportation. Compared with ordinary steel, SUS316 stainless steel contains molybdenum, offering stronger resistance against chloride ion corrosion, making it especially suitable for chlorine and other highly corrosive gases.

Beyond material choice, the structural design of blow-through rotary valves further enhances durability. Sealing components are made from wear-resistant, corrosion-resistant polymers, reducing the likelihood of leakage. In addition, the blow-through function clears residual gases in the chamber, preventing buildup that could accelerate corrosion.

By selecting the right materials, blow-through rotary valves not only extend equipment service life but also reduce maintenance frequency and costs, improving production continuity. For plants operating in highly corrosive environments, this is not only a safety requirement but also a key strategy for improving efficiency. Therefore, material selection plays a decisive role in valve application and is vital for sustainable industrial operations.
