· Special Blade Design: Adopts an elliptical blade (disc) combined with a beveled sealing structure, perfectly solving the problem of thermal expansion and contraction in environments with high temperature differences, and effectively overcoming the phenomenon of incomplete closing caused by carbon accumulation after long-term use. In addition, the beveled closing design significantly reduces the operating torque, effectively controlling the valve cost.

· Zero Leakage in Closed State: Innovatively adopts a double-layer blade structure. When the valve is in the closed state, compressed air is introduced between the double-layer blades to maintain positive pressure, thereby achieving true zero leakage.

· Special Stem Seal Design: Graphite packing rings are scientifically configured between the valve stem and the shaft sleeve. This design serves the dual functions of sealing and lubrication. While ensuring highly reliable sealing, it maintains a low friction torque and extends the service life.

· Multi-Field Application Scenarios: In addition to marine shipping (main engine exhaust desulfurization and denitrification), it is also widely used in key industrial fields such as the power industry (flue gas purification systems in coal-fired power plants), steel and metallurgy (sintering machines, blast furnace gas treatment), and the chemical and petrochemical industry (flue gas treatment in catalytic cracking units).
