Detail Information

Product Name: Hydraulic Slurry Knife Gate Valve
Body Material: Ductile Iron GGG40
Size: 24 Inch, DN600
Pressure: Class 150 LB, PN20
End Connection: Wafer
Operation: Hydraulic Actuator

The Integral Slurry Valve is a full-bore valve designed with a flow channel fully wrapped in wear-resistant polyurethane. This construction ensures that the flushing medium never comes into contact with the metal valve body, significantly extending the valve's wear resistance and service life.
With its full-diameter design, the flow channel matches the pipeline's inner diameter, preventing the formation of eddy currents and minimizing erosion. When fully opened, the valve plate lifts into the valve chamber, avoiding direct contact with the medium, which further enhances the disc's longevity and performance. This design effectively reduces wear and ensures extended operational life in challenging slurry applications.

Product Features

» Self-Cleaning Disc Function: The valve plate includes an integrated self-cleaning scraper inside the sleeve. As the valve plate moves up and down, it autonomously cleans its surface to prevent clumping, reduce switch torque, and avoid 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 design offers improved sealing, longer lifespan, and ease of replacement.
» Self-Flushing Valve Seat Structure: The self-flushing design of the valve seat prevents the sedimentation of slurry at the bottom, ensuring 100% zero leakage every time the valve is closed.
» Easy-to-Replace Seat: The removable valve seat and upper sealing structure allow for on-site replacement of worn components, such as the liner or upper seal. This feature restores the valve to its original performance and extends service life, with replacement costs being only 15-20% of the entire valve.
