Detail Information

Product Name: Pneumatic Actuated Slurry Knife Gate Valve
Features: Bidirectional, Full Bore
Body Material: Ductile Iron GGG40
Size: DN100, 4 Inch
Pressure: PN10, Class 150 LB
End Connection: Wafer
Operation: Pneumatic Actuator

The integral slurry valve is a full-bore design, with the valve body's flow channel entirely coated in wear-resistant polyurethane. This design prevents the flushing medium from coming into contact with the metal valve body, significantly extending its wear resistance. The valve features a full-diameter flow channel, matching the pipeline's inner diameter. This alignment minimizes the creation of eddy currents, reducing erosion. When fully opened, the valve plate lifts into the valve chamber, avoiding direct contact with the medium, effectively extending the disc's service life.

Product Features

» Self-Cleaning Disc Function: The valve features a built-in scraper on the valve plate. As the valve plate moves up and down, it automatically cleans the surface to prevent clogging, minimizing increased switching torque or blockage.
» Integrated Elastomeric Filler: The sealing filler is molded from wear-resistant, high-rebound rubber, tightly sealed with the stuffing box and polyurethane valve liner. This enhances sealing, extends the lifespan, and simplifies replacement.
» Self-Flushing Valve Seat Structure: The valve seat is designed with a self-flushing mechanism that prevents sediment build-up, ensuring 100% zero leakage every time it closes.
» Easy Seat Replacement: The removable valve seat and upper sealing structure allow for on-site replacement of worn parts, such as the liner or upper seal. This restores the product to its original service life, with replacement costs being only 15- 20% of the valve's total cost.
