Full Bore Knife Gate Valve, CF8M, 16 Inch, CL150, Pneumatic

The Full Bore Slurry Knife Gate Valve is designed for efficient flow control in demanding slurry applications. Made from ASTM A351 CF8M stainless steel, it ensures durability and corrosion resistance. This 16-inch (DN400) valve operates at Class 150 LB and PN16 pressure ratings, offering bidirectional flow control. Equipped with a pneumatic actuator for easy operation, it features flanged connections for secure installation.

The integral slurry valve is a full-bore design, with the valve body’s flow channel entirely coated in wear-resistant polyurethane. This design ensures that the flushing medium never comes into contact with the metal valve body, significantly extending its wear resistance. The full-diameter flow channel aligns seamlessly with the pipeline’s inner diameter, preventing the formation 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 effectively prolongs the service life of the disc.

Product Features

» Self-Cleaning Function of Disc
   Valve Plate Scraper: The valve features a self-cleaning scraper inside the sleeve. As the valve plate moves up and down, the scraper autonomously cleans the surface, preventing clumping and reducing switch torque or blockage.
» Integrated Elastomeric Filler
   Wear-Resistant Rubber Body: The integrated sealing filler is molded from high-rebound, wear-resistant rubber. It provides a tight seal with the stuffing box and polyurethane valve liner, ensuring better sealing, longer lifespan, and easier replacement.
» Self-Flushing Structure of Valve Seat
   Prevents Sedimentation: The self-flushing structure of the valve seat prevents sedimentation of bottom slurry, ensuring 100% zero leakage every time the valve is closed.
» Easy-to-Replace Seat
   Removable Components: The valve seat and upper sealing structure are removable. If the liner or upper seal shows wear during service, these components can be replaced on-site. This restores the valve to its original service life at a fraction of the cost (15-20%) compared to replacing the entire valve.
