Butterfly Dampers – Series 1901

Precision Air & Gas Flow Control Solutions by SUDE Engineering Pvt Ltd.

SUDE Engineering Pvt. Ltd. is a leading Indian manufacturer of high-performance Butterfly Dampers, designed and engineered to deliver precise regulation, reliable modulation, and positive isolation of air and gas flow across a wide range of industrial process applications.

A Butterfly Damper operates using a centrally mounted blade (disc) fixed to a heavy-duty shaft. The disc rotates smoothly within the duct or pipeline to control flow rates or achieve complete shut-off when required. This simple yet highly effective design ensures minimal pressure loss, fast response, and stable operation, even in large-diameter and high-velocity systems.

SUDE Butterfly Dampers are engineered for continuous, intermittent, and severe service conditions, making them suitable for high-temperature, abrasive, corrosive, and dust-laden media. Precision-machined components, optimized sealing arrangements, and robust construction ensure tight shut-off performance, reduced leakage, and extended service life with minimal maintenance.

Our dampers are available in circular, square, and rectangular configurations, with concentric or offset blade designs to suit on/off, throttling, or modulating duties. Multiple sealing options—ranging from metal-to-metal to soft seals—allow customization based on operating temperature, pressure, and process media.

Designed in compliance with international standards and customer specifications, SUDE Butterfly Dampers are extensively used in HVAC systems, power plants, steel and cement industries, chemical and petrochemical plants, and pollution control equipment. When integrated with SDTORK Electric, Pneumatic, or Hydraulic Actuators, they provide a complete, intelligent, and automated flow-control solution tailored for modern industrial environments.
