Zirconium gate valves, zirconium globe valves, zirconium ball valves... Introduction to zirconium: Zirconium is a metallic element used in the nuclear industry and as a corrosion-resistant material in chemical applications under high temperatures and pressures. One of the high-melting-point metals, appearing light gray in color. Density is 6.49 grams/cm3. Melting point: 1852±2°C, boiling point: 4377°C. Oxidation states of +2, +3, and +4. The first ionization energy is 6.84 electron volts. A layer of oxide film easily forms on the surface of zirconium, giving it a glossy appearance, so its look is similar to that of steel. It is corrosion-resistant and insoluble in hydrofluoric acid and aqua regia ； At high temperatures, it can react with non-metallic elements and many metallic elements to form solid solution compounds. Zirconium and zirconium alloy grades: Applications of zirconium valves: In the civil industry, zirconium materials exhibit excellent resistance to corrosion in both oxidative and reducing media. In particular, they resist corrosion from reducing hydrochloric acid and sulfuric acid at temperatures above 100°C, as well as from phosphoric acid and acetic acid. Their corrosion resistance is far superior to that of other materials such as titanium alloys, nickel, and nickel alloys; in fact, their corrosion resistance is one to several orders of magnitude higher than that of nickel alloys. Zirconium boasts a range of excellent properties, including high temperature resistance, good corrosion resistance, machinability, superior performance, and a low thermal neutron absorption cross-section. It is therefore an important structural material for nuclear reactors. Zirconium and its alloys are unique in terms of their corrosion resistance in alkali solutions of various concentrations as well as in molten alkalis, even outperforming tantalum. The series of zirconium valves developed by our company are widely used in the chlor-alkali industry, soda ash industry, pharmaceutical industry, fertilizer industry, fine chemical industry, textile fiber synthesis and dyeing industries, as well as in the production of basic organic acids and inorganic salts, and in the nitric acid industry. Features of zirconium valves: Features of zirconium ball valves: Zirconium ball valves have low flow resistance; among all types of valves, they present the lowest fluid resistance, and even reduced-diameter ball valves have relatively low flow resistance. The switching is fast and convenient; by rotating the valve body 90°, the ball valve reaches its fully open or fully closed position, allowing for quick opening and closing
