Electric Knife Gate Valve is designed for heavy-duty, precise shut-off and automated isolation of thick slurries, viscous fluids, dry bulk solids, and wastewater. Equipped with an electric motor actuator, this valve delivers high linear thrust to slice cleanly through suspended solids and build-ups, ensuring a tight seal without clogging the flow line.

Engineered with a narrow, space-saving wafer or lugged body, the electric knife gate valve provides reliable bi-directional or uni-directional isolation in abrasive and demanding environments. Its linear drive mechanism ensures controlled, repeatable cycling, making it an ideal choice for automated process lines where pneumatic air lines are unavailable or where precise, remote multi-positioning is required. Widely used across mining, pulp and paper, municipal wastewater, power generation, and chemical processing, it safeguards system efficiency while minimizing maintenance overhead.

Key Features

  • High-Thrust Electric Actuation: Integrated electric motor drive ensures powerful, smooth linear gate travel capable of cutting through heavy media and solids.

  • Self-Cleaning Blade Geometry: Beveled knife-edge disc actively shears through dense slurry, fibers, and powders to prevent gate jamming.

  • Compact Wafer/Lug Profile: Low face-to-face dimensions allow easy installation in tight piping configurations.

  • Robust Sealing Options: Available with metal-to-metal seating for high-temperature/abrasive lines or soft resilient seats (EPDM/PTFE/Viton) for zero-leakage shut-off.

  • Automation & Control Integration: Easily equipped with smart position controllers, limit switches, and bus communications (Modbus/Profibus) for seamless PLC/DCS operation.

Brands We Provide
