A Butterfly Damper is a type of valve used to regulate the flow of air, gases, or liquids in various industrial and HVAC systems. It consists of a circular disc or "butterfly" that pivots around a central axis within a duct or pipe. When the butterfly is rotated, it adjusts the flow by partially or fully opening or closing the passage, allowing for precise control of airflow, gas flow, or liquid flow. The simple design of the butterfly damper makes it ideal for a wide range of applications, offering both cost-effective and efficient flow control.

Key Features

• Disc Shape: The key feature of a butterfly damper is its circular disc (often referred to as the "butterfly") which rotates to control the flow of air or gases. The disc is usually mounted on a shaft, which allows it to pivot and adjust the opening.
• Quick Response: The damper provides fast and efficient operation, quickly responding to changes in the control system.
• Material Variety: Butterfly dampers are constructed from a wide range of materials, including steel, stainless steel, cast iron, and aluminum, depending on the application and environmental conditions.
• Compact Design: The compact design of butterfly dampers makes them ideal for space-constrained installations, especially in areas where full-sized valves or other control mechanisms would be too bulky.
• Sealing: Butterfly dampers can be equipped with sealing elements to ensure minimal leakage when closed. These seals improve the damper’s efficiency by preventing unwanted flow and enhancing system control.
