Chainwheel Knife Gate Valve
For pipelines with large-diameter or hard-to-reach valves, chainwheel knife gate valves provide safe, reliable, and easy manual operation. Designed for slurries, powders, viscous fluids, and wastewater, these valves enable precise flow control even in high-torque or elevated installations.
TOT chainwheel knife gate valves feature a sharp, blade-shaped gate that moves perpendicular to the flow, ensuring full bore flow and tight shut-off while allowing operation from a distance via a chainwheel mechanism.
Chainwheel knife gate valves are ideal for systems where handwheel operation is impractical due to valve size or elevation, commonly used in wastewater, mining, chemical, and pulp & paper industries.
Made from high-quality stainless steel, carbon steel, or lined materials, these valves provide corrosion and abrasion resistance while ensuring long-term reliable performance.
Full Body & Gate: Durable construction ensures long-term use in abrasive or corrosive environments.
Customizable for Your Flow System: Face-to-face dimensions, flanges, and chain length can be adapted to your project requirements.
Factory-Tested Before Delivery: Hydrostatic and seat testing guarantee reliable performance.
ISO, CE, and API Certified Manufacturing: Ensuring quality and international compliance.

FAQ-Chainwheel Knife Gate Valve
A knife gate valve operated manually via a chainwheel, allowing remote operation of large or elevated valves.
Slurries, powders, viscous fluids, non-abrasive chemicals, and wastewater.
The blade gate moves perpendicular to the flow, cutting through media while the chainwheel allows operation from a distance.
Yes — chainwheel valves can often be retrofitted with pneumatic or electric actuators.
Routine inspection of gate, seat, packing, and chain; minimal maintenance for durable stainless steel, duplex, PVC, or lined bodies.
Consider media type, valve size, pressure, temperature, installation height, and chainwheel length. TOT provides expert guidance.
