Electric Knife Gate Valves
When your industrial system requires precise flow control and remote operation, electric knife gate valves provide reliable automation for demanding applications. Designed for slurries, wastewater, powders, corrosive or viscous media, our electric knife gate valves combine durable construction with convenient, fully controlled actuation.
TOT electric knife gate valves feature a sharp, blade-shaped gate that moves perpendicular to the flow, designed to control difficult media while allowing automated operation for improved efficiency and reduced manual intervention.
Electric knife gate valves are ideal when manual operation is impractical or unsafe, ensuring tight shut-off and reliable performance in automated pipelines.
Made from high-quality stainless steel, carbon steel, or lined materials, these valves provide excellent corrosion resistance, wear resistance, and long-term reliability under automated actuation.
Full Stainless Steel / Carbon Steel Body & Gate: Provides durability and corrosion resistance in harsh industrial environments.
Customizable Actuation & Flow System: Face-to-face dimensions, flanges, and actuator specifications can be tailored to your project requirements.
Factory-Tested Before Delivery: Each valve undergoes hydrostatic and seat testing to ensure performance under full load.
ISO, CE, and API Certified Manufacturing: Ensuring consistent quality and compliance with international standards.
Contact us today to automate your flow system, increase efficiency, and minimize downtime.
