Wafer Type Damper Butterfly Valve

ALIS Valves offers Wafer Type Damper Butterfly Valves for industrial applications requiring efficient flow regulation and isolation in air, gas and compatible process systems. These valves feature a rotating butterfly disc that controls the flow passage by changing its position within the pipeline or duct. The wafer-style body is designed to fit between compatible flanges, providing a compact installation that helps reduce space requirements in industrial systems. Depending on the application, the valve can be configured with suitable body and disc materials, shaft sealing arrangements and operating mechanisms to accommodate the specified temperature, pressure and process media. Manual, pneumatic or electric actuation options may be available to support different operating requirements, including automated flow adjustment and integration with industrial control systems.

Wafer Type Damper Butterfly Valves are used in ventilation systems, HVAC installations, industrial air handling units, exhaust systems, power plants, dust collection equipment and process gas applications. They are suitable for controlling airflow and compatible gases where the valve’s design, sealing performance and operating ratings match the process requirements. Important selection factors include valve size, duct or flange dimensions, operating temperature, differential pressure, gas composition, body and disc materials, required leakage performance and operating torque. The actuator should be selected according to the disc size, pressure conditions and required control function. Buyers should also confirm whether the application requires simple flow regulation, shut-off service or a low-leakage damper design, as not all damper butterfly valves provide tight isolation. Choosing the appropriate valve configuration helps support efficient airflow management, reliable operation and long-term service performance under the intended working conditions.
