Bevel Gear Knife Gate Valves
For large-diameter pipelines where manual operation of heavy valves is required, bevel gear knife gate valves provide safe, efficient, and reliable operation. Designed for slurries, powders, viscous fluids, and wastewater, these valves combine durable construction with mechanical advantage for easy operation.
TOT bevel gear knife gate valves feature a sharp, blade-shaped gate that moves perpendicular to the flow, allowing full bore flow and tight shut-off while reducing the effort needed to operate large valves through a bevel gear mechanism.
Bevel gear knife gate valves are ideal for systems where high-torque, manual operation is needed, making them perfect for wastewater, mining, chemical, and pulp & paper industries.
Made from high-quality stainless steel, carbon steel, or lined materials, these valves offer corrosion and abrasion resistance while ensuring long-term reliable performance.
Full Body & Gate: Durable construction for long-term use in abrasive or corrosive environments.
Customizable for Your Flow System: Face-to-face dimensions, flanges, and gear ratios can be tailored to your project requirements.
Factory-Tested Before Delivery: Hydrostatic and seat testing ensure optimal performance.
ISO, CE, and API Certified Manufacturing: Guaranteed quality and compliance with international standards.

FAQ-Bevel Gear Knife Gate Valve
A knife gate valve operated manually via a handwheel with a bevel gear mechanism, reducing the effort needed to operate large or high-torque valves.
Slurries, powders, viscous fluids, non-abrasive chemicals, and wastewater.
The blade gate moves perpendicular to the flow, cutting through media while the bevel gear provides mechanical advantage for easier manual operation.
Yes — bevel gear valves can sometimes be retrofitted with electric or pneumatic actuators.
Routine inspection of gate, seat, packing, and gear; minimal maintenance for durable stainless steel, duplex, PVC, or lined bodies.
Consider media type, valve size, pressure, temperature, and required manual torque. TOT provides expert guidance for selection.
