Product Name: Ductile Iron Slurry Knife Gate Valve
Body Material: Ductile Iron GGG40
Size: DN150, 6 Inch
Pressure: PN10, Class 150 LB
End Connection: Wafer
Operation: Manual
The integral slurry valve is a full-bore type, with the valve body’s flow channel fully wrapped in wear-resistant polyurethane. This design ensures that the flushing medium does not come into contact with the metal valve body, significantly extending its wear resistance. The full-diameter flow channel aligns with the inner diameter of the pipeline, preventing the formation of eddy currents and reducing erosion. When fully opened, the valve plate lifts into the valve chamber, avoiding direct contact with the medium, which effectively extends the service life of the disc.

Product Features
» Self-Cleaning Function of Disc: The valve plate features a self-cleaning scraper inside the sleeve. As the valve plate moves up and down, it automatically cleans the surface to prevent clumping, reduce switch torque, and avoid blockage.
» Integrated Elastomeric Filler: The sealing filler is made from wear-resistant, high-rebound rubber, ensuring a tight seal with the stuffing box and polyurethane valve liner. This enhances sealing performance, extends lifespan, and allows for easier replacement.
» Self-Flushing Structure of Valve Seat: The valve seat's self-flushing design prevents sediment buildup, ensuring zero leakage every time the valve closes.
» Easy-to-Replace Seat: The valve seat and upper sealing structure are removable. If the liner or upper seal wears during use, these parts can be replaced on-site, restoring the product’s original service life at just 15-20% of the total replacement cost.
