Direct Drive Rotary Valve
A multi-blade rotor is designed inside the rotary valve, which rotates at a low speed in a cylindrical casing. The very small gap between the rotor and the inner cavity of the casing can effectively prevent the reverse flow of airflow and ensure the stability of the air pressure in the system and the normal transportation of materials. .

Sprocket Driven Rotary Valve
The conveying medium of the rotary valve is divided into: granular body, fine powder, irregular shape (such as PET bottle flakes). Wangda engineers choose the optimal design plan of the rotary valve according to the characteristics of the conveying medium and use conditions, and perfectly solve the "jam" , "Pumping" phenomenon, to ensure uniform and stable transportation of materials.
