Product Description

Ceramic star valves are essential components in pneumatic output systems for both pressure and negative pressure applications. These valves provide uniform and continuous material supply to conveying pipes, ensuring stable gas-solid flow for proper pneumatic conveying operation. Additionally, they effectively separate upper and lower air pressure in unloading systems, serving as reliable air locks.
