Detail Information

Product Name: Pneumatic Slurry Knife Gate Valves
Body Material: Ductile Iron GGG40
Size: 16 Inch, DN400
Pressure: Class 150 LB, PN16
End Connection: Flanged
Operation: Pneumatic Actuator
Medium: Slurry

The Integral Slurry Valve is a full-bore valve designed with a wear-resistant polyurethane coating that wraps around the entire valve body's flow channel. This design ensures the flushing medium never comes into direct contact with the metal valve body, significantly extending its anti-wear lifespan. The full-diameter flow channel matches the inner diameter of the pipeline, preventing eddy currents and reducing erosion. When fully opened, the valve plate lifts into the valve chamber without direct exposure to the medium, further enhancing the disc's service life.

Product Features

» Self-Cleaning Disc Function: The valve features an integrated scraper inside the sleeve that automatically cleans the valve plate's surface during movement, preventing clumping and reducing switch torque or blockage.
» Integrated Elastomeric Filler: The sealing filler is made from wear-resistant, high-rebound rubber and tightly seals with the stuffing box and polyurethane valve liner, offering improved sealing, a longer lifespan, and easier replacement.
» Self-Flushing Valve Seat: The self-flushing valve seat structure prevents slurry sedimentation at the bottom, ensuring 100% zero leakage each time the valve closes.
» Easy Seat Replacement: The removable valve seat and upper sealing structure allow for easy on-site replacement of worn components, restoring the valve to its original performance. The cost of replacement is only 15-20% of the entire valve, offering a cost-effective maintenance solution.
