The pneumatic louver valve is a new type of energy-efficient, high-performance product developed by our company. It is suitable for inlet applications of fans and ventilation ducts in industries such as metallurgy, mining, coal, building materials, chemical processing, and power generation, providing flow regulation in piping systems.
Featuring a novel design, rational structure, and light weight, this valve adopts a multi-shaft louver-type configuration. It offers uniform fluid distribution, low operating torque, and flexible and reliable operation. Equipped with the QZ series pneumatic actuator, it supports both independent operation and remote centralized control, making it an ideal airflow regulating device for various air duct systems.
