Sanitary Pneumatic V-Type Flange Ball Valve - VQ640F Kongge Technology is a ball valve with a rotating shut-off principle featuring a V-shaped notch ball core component. Based on field usage conditions, it can be paired with standard, enlarged size 1, or enlarged size 2 cylinders to achieve automated switching and cutting. It is suitable for stable control of pipeline media in systems handling fibers, fine solid particles, sticky sludge, slurries, and other working conditions. During the rotation process, the V-shaped notch and valve seat generate a high-torque shearing force that can cut off fibers and other impurities, with a self-cleaning function to prevent valve jamming. The double bearing structure ensures stable mechanical performance, low starting torque, sensitive switching, and stable response speed. Our company designs the materials for this product based on the field media conditions and can provide custom non-standard products. Customers need to call to specify requirements when ordering.
