Titanium Alloy Flange Gate Valve Corrosion Resistant Chemical Industrial Valve

Titanium alloy gate valves exhibit exceptional corrosion resistance to numerous corrosive media. This is attributed to titanium's strong affinity for oxygen, enabling it to readily react with oxygen and form a robust, dense, and passive oxide film on its surface. Consequently, titanium gate valves are widely used in pipelines transporting corrosive fluids. These valves find applications in the chlor-alkali industry, soda ash industry, pharmaceutical industry, fertilizer industry, fine chemical industry, textile fiber synthesis and dyeing industry, production of basic organic acids and inorganic salts, and nitric acid industry, delivering significant economic benefits to these sectors.

With the rapid development of heavy industries such as chemicals, petroleum, and power generation, the demand for titanium gate valves has surged. However, valve quality issues have frequently led to leaks, production halts, and major accidents, causing significant economic and safety losses. This has prompted most valve manufacturers to prioritize quality control. Recognizing that domestic valve production equipment remains relatively outdated, many companies have introduced advanced technologies and manufacturing systems from abroad, demonstrating strong commitment to improving valve quality. Consequently, numerous capable valve enterprises have emerged, significantly driving the growth of China's valve industry.

• 1. Elastic or rigid wedge gate valve;
• 2. Through-holes and shrinkage cavities;
• 3. Bolted or welded valve cover;
• 4. The valve cover and valve body lack a flange-based self-sealing connection structure;
• 5. Upgradable valve seat or main valve seat;
• 6. The inner surface of the titanium gate valve undergoes hardening treatment, forming a protective film that enhances corrosion resistance while significantly increasing surface hardness, ensuring smooth operation and reduced susceptibility to scratches.
