Diverter Damper
Diverter Damper – Series- 1905
SUDE Engineering Pvt. Ltd. designs and manufactures the Diverter Damper – Series 1905 as a heavy-duty solution for diverting, isolating, and controlling gas flow in large industrial ducting systems. Engineered for severe service conditions, SUDE Diverter Dampers ensure safe, efficient, and reliable gas management in critical process applications.
A SUDE Diverter Damper operates using a robust rotating or sliding blade mechanism, allowing hot gases or exhaust streams to be redirected between multiple outlets or completely isolated when required. The design ensures smooth operation, high structural stability, and dependable performance even under high temperature, high pressure, and fluctuating process conditions.
Manufactured with precision and stringent quality control, SUDE Diverter Dampers are ideally suited for power plants, gas turbine exhaust systems, waste heat recovery units (WHRU), refineries, cement, and steel plants.

Working Principle:
Open Position
Blade is aligned to allow gas to flow freely through the main duct path with no restriction.
Closing Motion
The actuator rotates or slides the blade into position, beginning to divert or isolate the gas flow.
Closed Position
The blade fully blocks or redirects the gas stream to a bypass outlet. High-performance sealing surfaces or pressurized air systems ensure tight shut-off during isolation.
Actuation Options:
Manual
Rarely used (due to large size and torque requirements)
Electric
Motor-driven for precise control
Pneumatic
Rapid operation for systems requiring quick response
Hydraulic
For large-scale or high-torque industrial applications
