Detail Information

Product Name: Hydraulic Actuated Slurry Knife Gate Valve
Body Material: Ductile Iron GGG40
Size: 20 Inch, DN500
Pressure: Class 150 LB, PN16
End Connection: Flanged
Operation: Hydraulic Actuator

The integral slurry valve is a full-bore type, with the valve body flow channel entirely coated in wear-resistant polyurethane. This design ensures that the flushing medium does not come into contact with the metal valve body, significantly extending its anti-wear lifespan. The full-diameter flow channel aligns with the inner diameter of the pipeline, preventing eddy currents in the medium and reducing erosion. When fully opened, the valve plate lifts into the valve chamber, avoiding direct contact with the medium, which helps to further extend the service life of the disc.

Product Features

» Self-Cleaning Function of Disc: The valve plate features a built-in self-cleaning scraper inside the sleeve. As the valve plate moves up and down, it autonomously cleans its surface to prevent clumping, reduced switch torque, or blockage.
» Integrated Elastomeric Filler: The sealing filler is molded from wear-resistant, high-rebound rubber, providing a tight seal with the stuffing box and polyurethane valve liner. This enhances sealing, prolongs the lifespan, and simplifies replacement.
» Self-Flushing Structure of Valve Seat: The valve seat's self-flushing design prevents sediment accumulation, ensuring 100% zero leakage every time the valve closes.
» Easy to Replace Seat: The removable valve seat and upper sealing structure allow for on-site replacement of worn liners or upper seals. The updated parts restore the valve's original service life, with replacement costs only 15-20% of the total machine cost.
