Electric Knife Gate Valve

Overview

Electric Knife Gate Valves are designed for automated flow control in pipelines, especially where slurries, viscous fluids, and solid materials are present. These valves use an electric actuator to control the movement of the knife gate, offering precise, remote control for industrial processes.

Product Features

1. Electric Actuation:
   • Automation: Equipped with an electric actuator that allows for automated and precise control of the valve operation, including opening, closing, and flow regulation.
   • Remote Control: The valve can be operated remotely via control signals, improving safety and efficiency in hazardous or hard-to-reach locations.
   • Customization: Various actuator types and brands can be used, depending on system requirements, including models with integrated positioners and feedback systems.
   • Power Supply: Standard options include AC (220V, 380V) or DC (24V) power supply, but can be customized based on user needs.
2. Knife Gate Design:
   • Gate Design: Features a sharp, knife-like gate that effectively cuts through solids, slurries, and fibrous materials, preventing clogging and ensuring smooth flow.
   • Zero Leakage: The valve ensures a tight seal, preventing leakage and ensuring isolation of the media when the valve is fully closed.
   • Bi-Directional: The knife gate design allows for flow control in both directions, providing flexibility for installation and operation.
3. Stainless Steel or Cast Steel Construction:
   • Material Options: Available in stainless steel, cast steel, or other materials depending on application needs, ensuring corrosion resistance, durability, and high performance in different environments.
   • Long Service Life: Stainless steel versions offer excellent resistance to rust, corrosion, and high-temperature conditions, ensuring long-term reliability.
4. Sealing System:
   • Resilient Sealing: Fitted with high-quality sealing materials such as PTFE or EPDM to ensure excellent sealing performance, preventing media leakage and ensuring operational safety.
   • Self-Cleaning: The knife gate’s self-cleaning action minimizes the buildup of debris or media on the sealing surfaces, reducing maintenance frequency.
5. Compact Design:
   • Space-Saving: The valve’s compact, slim design allows for installation in tight spaces without sacrificing performance.
   • Easy Installation: Flanged or wafer-style connections allow for straightforward installation in various pipeline configurations.
6. Low Maintenance:
   • Durable Components: High-quality materials and construction ensure low wear and tear, reducing the need for frequent maintenance.
   • Easy Access: Designed for easy maintenance, with simple actuator removal for servicing.
