Throttle Damper
Throttle Damper – Series 1928
Precision Flow Modulation for Ducts, Stacks, and Process Lines
The Throttle Damper – Series 1928 from SUDE Engineering Private Limited is a high-performance flow control device designed for precise regulation and modulation of airflow or gas flow within ducts, stacks, and process lines. Unlike conventional shut-off dampers that provide only full open/close isolation, the throttle damper enables continuous or proportional control, allowing fine adjustment of flow rates for system balancing, pressure regulation, and fan load optimization.
Engineered for demanding industrial and HVAC applications, the damper ensures smooth and accurate modulation while minimizing turbulence and pressure drop. Its durable blade and pivot mechanism provide consistent performance even under high-temperature, dust-laden, or corrosive air and gas conditions, ensuring operational efficiency and system stability.
Constructed from high-quality, robust materials, the throttle damper is designed for long-term service with minimal maintenance. Its precision engineering allows seamless integration into manual, pneumatic, or electric actuation systems, supporting automated process control and building management systems for responsive and reliable airflow management.
Widely used in power plants, steel and metallurgical industries, chemical processing units, HVAC systems, and industrial ventilation networks, the Throttle Damper reflects SUDE Engineering Private Limited’s commitment to durable design, precise flow control, and high-performance industrial solutions.

Working Principle:
Open Position
Damper blades are aligned with airflow direction, allowing maximum flow with minimal restriction.
Throttle / Modulating Mode
Blade(s) adjust to partially restrict the duct area, enabling accurate flow modulation or pressure control. Ideal for fan outlet control and process optimization.
Closed Position (Optional)
Provides substantial flow reduction (not 100% tight shut-off), used for isolating or limiting flow when required.
Actuation Options
Manual (lever, gearbox, hand wheel), Electric (modulating actuator with feedback 0–10V / 4–20mA), or Pneumatic (cylinder with positioner or solenoid) operation.
