Non-Backpressure Soft Contact CNC Plate Air Valve

The performance of air valves is crucial for efficient material stratification. The SKT Jigging Machine employs state-of-the-art air valve technology to ensure optimal material sorting. Traditional electric rotary valves are slow to open and challenging to adjust. In response, the SKT Jigging Machine introduced CNC pneumatic plate valve technology, offering quick opening and flexible adjustment.
