Product Range
Flue gas dampers, desulfurization dampers, slide gates, baffle gates, blind flange valves and quick-opening doors for boiler, flue and pulverized coal ducts.
High-temperature dampers and isolation gates engineered for boiler flue gas, desulfurization and denitrification systems.
Our damper family covers every isolation duty in a thermal power plant: louver-type double-layer desulfurization dampers with sealing air, electrically or hydraulically driven slide gate valves for flue gas, air and pulverized coal lines, blind flange (spectacle) valves for absolute gas shut-off, power-failure quick-opening gates for coking plant safety, and quick-opening chimney doors for inspection access. Every unit is sized for the actual temperature, dust load and duct cross-section, leakage-tested in the works and shipped with mating flanges, expansion joints and actuation.
