The sphere of the dual-phase steel ball valve is floating. Under the action of the medium pressure, the ball can generate a certain displacement and press on the sealing surface at the outlet end to ensure the sealing of the outlet end. Dual-phase steel ball valves are widely used in chemical, industrial, aviation, military, petrochemical, marine development, power industry and other industrial fields of acid, alkali, salt and harsh corrosion conditions.
The anti-intergranular corrosion resistance of the dual-phase steel ball valve material is superior to that of urea grade 316L, and it has the dual characteristics of ferrite and austenite. The strength and hardness are higher than 316L. Julong Company applies this material to urea methyl ammonium. The valve core of the liquid medium valve improves the intergranular corrosion resistance and erosion resistance of the dual-phase steel valve, and the valve for the urea synthesis tower with the extreme environment has also received satisfactory results.
