Motorized Knife Edge Gate Valve Wafer Semi Lug Type
“aline” Make Electrical Actuator Operated Knife Edge Gate Valve – Wafer Semi Lug Type is specially engineered for the reliable isolation of abrasive, viscous, slurry, powder, and bulk solid media in demanding industrial applications. The valve combines a heavy-duty knife edge gate valve with a high-performance multi-turn electric actuator, providing fully automated operation without manual intervention. Its sharp-edged stainless steel gate effectively cuts through thick media, ensuring dependable shut-off and uninterrupted process flow.
The electric actuator is available in ON/OFF and Modulating (4–20 mA) control options, allowing seamless integration with PLC, DCS, SCADA, and BMS automation systems. The Wafer Semi Lug Type design offers easy installation between flanges while providing excellent strength, stability, and leak-tight sealing. Manufactured using premium-quality materials, the valve delivers long service life, minimal maintenance, and outstanding performance in harsh industrial environments.
ALINE Electrical Actuator Operated Knife Edge Gate Valves are widely used in mining, cement, power plants, pulp & paper, wastewater treatment, chemical processing, sugar plants, steel industries, food processing, and bulk material handling systems.
