Features of Pneumatic Actuator Butterfly Valve

Fast Quarter-Turn Automation

Equipped with a pneumatic actuator, the valve achieves rapid 90° opening and closing operation, providing faster response than manual valves and improving process efficiency in automated systems.


High Torque Output with Compact Design

The pneumatic actuator delivers reliable torque output in a compact package, ensuring stable operation even under high-pressure or high-cycle applications.


Excellent Flow Control Performance

The optimized butterfly disc design provides low pressure drop, high flow capacity, and smooth throttling performance for precise fluid regulation.



Multiple Actuator Configurations

Supports double-acting and spring-return pneumatic actuators, allowing flexible selection for fail-open, fail-close, or fail-in-place safety requirements.


Easy Integration with Automation Systems

Designed with ISO 5211 actuator mounting and NAMUR interfaces, enabling simple installation of solenoid valves, positioners, limit switches, and smart control accessories.


Low Maintenance & Long Service Life

The streamlined structure with fewer moving parts reduces wear, minimizes maintenance requirements, and extends operating life in demanding environments.
