Pneumatic Actuator Operated Damper High Temperature Butterfly Damper Motorized Butterfly Damper

Pneumatic Ventilation Butterfly Valve Product Overview The pneumatic ventilation butterfly valve is a high-performance valve designed for industrial, metallurgical, and environmental protection applications. This valve utilizes the same material as the valve body to create a durable sealing ring and employs electric or pneumatic transmission mechanisms. The operating temperature range of the valve is contingent upon the valve body material, with a nominal pressure of ≤0.6MPa. It is ideally suited for ventilation and medium flow adjustment in various pipeline systems.
Key Features of Pneumatic Ventilation Butterfly Valve:
- Innovative and rational design, featuring a unique structure, lightweight construction, and rapid opening and closing capabilities.
- Low operating torque, ensuring ease of operation, labor-saving, and agility.
- Utilizes appropriate materials to accommodate low, medium, and high medium temperatures, as well as corrosive media.
Pneumatic Ventilation Butterfly Valve Actuator: The valve is equipped with a new series AT type pneumatic actuator, available in double-acting and single-acting (spring return) configurations, utilizing gear transmission for safe and reliable operation. Larger diameter valves employ a series AW type pneumatic actuator with fork transmission, boasting a reasonable structure, substantial output torque, and both double-acting and single-acting options.
- Gear-type dual piston design delivers significant output torque in a compact form factor.
- The cylinder is crafted from aluminum, resulting in a lightweight and visually appealing construction.
- Manual operating mechanisms can be installed at the top and bottom for flexibility.
- Rack-type connections allow for adjustments to the opening angle and rated flow.
- The actuator can be fitted with electrical signal feedback indication and various accessories to facilitate automated operation.
- Compliance with IS05211 standard connection ensures ease of product installation and replacement.
- Adjustable screws on both ends provide a ±4° adjustable range at 0° and 90° for the standard product, ensuring synchronization accuracy with the valve.
