Detail Information

Product Name: Bevel Gear Slurry Knife Gate Valve
Body Material: GGG40, Ductile Iron
Size: DN200, 8 Inch
Pressure: PN10, Class 150 LB
End Connection: Lug
Operation: Bevel Gear
Medium: Slurry

The integral slurry valve is a full-bore design, with the valve body’s flow channel fully encased in wear-resistant polyurethane. This innovative construction ensures that the flushing medium never comes into contact with the metal valve body, significantly extending its wear resistance. The valve's full-diameter design aligns the flow channel with the pipeline's inner diameter, preventing the generation of eddy currents and minimizing erosion. When fully opened, the valve plate is lifted into the valve chamber, avoiding direct contact with the medium, which further enhances the disc's service life.

Product Features

» Self-Cleaning Disc Function: Equipped with a self-cleaning valve plate scraper inside the sleeve. As the valve plate moves up and down, it automatically cleans the surface, preventing clumping, reducing switch torque, and avoiding blockage.
» Integrated Elastomeric Filler: The sealing filler is made from wear-resistant, high-rebound rubber, molded for a tight seal with the stuffing box and polyurethane valve liner. This design enhances sealing, extends lifespan, and allows for easier replacement.
» Self-Flushing Valve Seat Structure: The self-flushing valve seat prevents sediment buildup in the slurry, ensuring 100% zero leakage each time the valve is closed.
» Easy Seat Replacement: Features a removable valve seat and upper sealing structure. If the liner or upper seal wears out during service, components can be replaced on-site, restoring the product's original service life at just 15-20% of the full machine replacement cost.
