Ductile Iron Knife Gate Valve DN300

The Ductile Iron Knife Gate Valve DN300 is engineered for efficient isolation and flow control in demanding industrial applications. Designed for slurry, wastewater, and abrasive media, this valve features a sharp blade mechanism that cuts through thick fluids, ensuring reliable sealing and minimal clogging. With a robust ductile iron (GGG50) body, the DN300 knife gate valve is ideal for mining, chemical processing, pulp & paper, and water treatment plants. Its bidirectional sealing capability and low-maintenance design make it a cost-effective solution for high-pressure and high-solid environments.

High-Strength Ductile Iron Construction – Ensures durability and corrosion resistance in harsh conditions.

Sharp Knife-Edge Gate – Cuts through slurries, sludge, and viscous fluids without clogging.

Bidirectional Sealing – Provides leak-proof performance in both flow directions.

Multiple Seat Options – Available with EPDM, NBR, or metal seats for chemical compatibility.

Flanged Ends (PN10/16, ANSI 150) – Complies with ISO 7005 standards for easy pipeline integration.

Manual, Pneumatic, or Electric Actuation – Customizable for automated control systems.

Compact & Lightweight Design – Simplifies installation and maintenance.



Applications of DN300 Knife Gate ValveThis heavy-duty knife gate valve is widely used in:

● Mining & Mineral Processing – Handling slurries, tailings, and abrasive materials.

● Wastewater & Sewage Treatment – Controlling sludge, grit, and industrial effluents.
