Hydraulic Knife Gate Valve
When your industrial system handles heavy, abrasive, or high-pressure media, hydraulic knife gate valves provide powerful, precise, and automated operation. Designed for slurries, powders, viscous fluids, wastewater, and corrosive chemicals, our hydraulic knife gate valves deliver reliable isolation with minimal manual effort.
TOT hydraulic knife gate valves feature a sharp, blade-shaped gate that moves perpendicular to the flow, designed to cut through tough media and ensure full bore flow and tight shut-off under hydraulic actuation.
Hydraulic knife gate valves are ideal for large-scale pipelines, high-pressure applications, or situations where electric or pneumatic actuation may not provide sufficient force.
Made from high-quality stainless steel, carbon steel, or lined materials, these valves provide excellent corrosion and abrasion resistance while offering reliable long-term performance with hydraulic actuation.
Full Stainless Steel / Carbon Steel / Lined Body & Gate: Durable construction ensures long service life in harsh environments.
Customizable for Your Flow System: Face-to-face dimensions, flanges, and hydraulic actuator specifications can be tailored to your project requirements.
Factory-Tested Before Delivery: Each valve undergoes hydrostatic and seat testing to meet international standards.
ISO, CE, and API Certified Manufacturing: Ensuring global-quality compliance and professional engineering.
Contact us today to optimize your heavy-duty flow system and minimize operational downtime.

FAQ-Hydraulic Knife Gate Valve
A knife gate valve equipped with a hydraulic actuator for high-force, automated operation, ideal for large, abrasive, or high-pressure pipelines.
Slurries, powders, viscous fluids, corrosive chemicals, and wastewater.
The blade gate moves perpendicular to the flow, cutting through media while the hydraulic actuator provides high-force opening and closing.
Yes — hydraulic valves can be connected to centralized hydraulic control systems or SCADA.
Routine inspection of actuator, gate, and seat; minimal maintenance for durable stainless steel or lined bodies.
Consider media type, valve size, pressure, temperature, and required hydraulic actuation force. TOT provides expert selection guidance.
