Electric Knife-Type Gate Valve
The Electric Knife-Type Gate Valve is a high-performance automated isolation valve specifically designed for handling slurries, wastewater, pulp, powders, granular materials, and other media containing suspended solids. Equipped with an electric actuator, the valve enables remote operation, automated process control, and seamless integration into industrial control systems.
The sharp-edged gate effectively cuts through fibrous, viscous, and solid-laden media, ensuring reliable shut-off performance even in challenging operating conditions. Its compact structure, bidirectional sealing options, and low maintenance requirements make it an ideal solution for modern industrial automation systems.
Designed to meet international standards and project requirements, our Electric Knife-Type Gate Valves are widely used in water treatment, mining, pulp and paper, chemical processing, power generation, and bulk material handling industries throughout North America, the Middle East, and global markets.
We provide comprehensive OEM and ODM manufacturing services to meet project-specific requirements and regional standards.
