Manual Handwheel Knife Gate Valve
For industrial pipelines where simple, reliable, and cost-effective flow control is needed, manual handwheel knife gate valves provide durable, easy-to-operate solutions. Designed for slurries, wastewater, powders, and viscous fluids, these valves ensure precise control and tight shut-off without the need for power.
TOT manual handwheel knife gate valves feature a sharp, blade-shaped gate that moves perpendicular to the flow, ideal for handling fibrous, viscous, or slurry media in chemical, wastewater, and industrial applications.
Manual knife gate valves are a dependable choice for systems where automation is not required, offering long service life, low maintenance, and robust performance.
Made from high-quality stainless steel, carbon steel, PVC, or lined materials, these valves are corrosion- and wear-resistant, ensuring reliable operation even in harsh industrial environments.
Full Body & Gate: Durable construction for long-term use in abrasive or corrosive conditions.
Customizable for Your Flow System: Face-to-face dimensions, flanges, and other specifications can be tailored to your project needs.
Factory-Tested Before Delivery: Each valve undergoes hydrostatic and seat testing to ensure reliable performance.
ISO, CE, and API Certified Manufacturing: Guaranteed quality and compliance with international standards.

FAQ-Manual Handwheel Knife Gate Valve
A knife gate valve operated manually via a handwheel (or optional chainwheel), providing reliable flow control for slurries, powders, and viscous fluids.
Slurries, powders, viscous fluids, non-abrasive chemicals, and wastewater.
The blade gate moves perpendicular to the flow, slicing through media and sealing tightly, controlled manually via handwheel.
Yes — manual valves can often be retrofitted with pneumatic or electric actuators if automation is required.
Periodic inspection of the gate, seat, and packing; minimal maintenance for durable stainless steel, duplex, PVC, or lined bodies.
Consider media type, valve size, pressure, temperature, and operation requirements. TOT provides expert guidance for selection.
