Description

The Pneumatic Actuator with Butterfly Valve and Limit Switch Box Assembly is a complete solution for automated flow control of liquids, gases, and air in industrial piping systems. The system operates by rotating the butterfly valve disc through 90° to accurately and quickly open or close the flow path, while the pneumatic actuator ensures fast response and reliable operation under various working conditions.

The Limit Switch Box provides valve position feedback (open/closed), enabling remote monitoring and control through industrial automation systems such as PLC and DCS, thereby improving operational efficiency and system reliability.

UNOX offers this assembly with an advanced engineering design and premium-quality materials to ensure stable performance, long service life, and easy installation and maintenance.
