Electric Damper Butterfly Valve

ALIS Valves offers Electric Damper Butterfly Valves for industrial applications requiring automated airflow regulation and reliable control of gases in ventilation and process systems. These valves feature a rotating butterfly disc that adjusts the flow passage to regulate or restrict the movement of air and compatible gases. An electric actuator drives the disc according to a control signal, allowing remote operation and integration with programmable logic controllers (PLCs), building management systems and other industrial automation platforms. Depending on the application, the valve can be configured with suitable body and disc materials, shaft arrangements and sealing components to meet the required operating conditions. Electric actuation supports controlled positioning and repeatable operation, making these valves suitable for systems where automated airflow management is important.

Electric Damper Butterfly Valves are used in HVAC systems, industrial ventilation, exhaust ducts, power generation plants, air handling units, dust collection systems and process gas installations. They can be selected for airflow regulation and compatible gas-handling applications where the valve’s pressure, temperature and leakage ratings meet the system requirements. Important selection factors include valve size, duct or flange connection dimensions, operating temperature, differential pressure, gas composition, body and disc materials, required leakage performance, actuator torque and electrical supply specifications. Buyers should also consider the control signal, positioning accuracy, operating time and whether the application requires modulating control or simple open-close operation. Since damper valves can vary significantly in their sealing capabilities, the required shut-off performance should be confirmed before selection. Choosing the appropriate valve and actuator configuration helps support efficient airflow control, dependable automation and consistent operation under the intended working conditions.
