Description
Knife Edge Gate Valve - Severe Service Slurry & Solid Flow Isolation
FlowBiz Exports is a leading manufacturer and exporter of heavy-duty Knife Edge Gate Valves. Specifically engineered to handle thick slurries, viscous fluids, dry powder, and media containing suspended solids, these valves feature a sharp, bevel-edged gate disc that easily cuts through dense media to establish tight, reliable isolation without clogging.
Key Features & Operational Superiority
- Sharp Beveled Gate Disc: Precision-machined, self-cleaning knife edge slices through fibrous materials, thick sludge, and heavy slurries during closure.
- Non-Clogging Body Design: Streamlined cavity-free bottom profile prevents media buildup, packing, or clogging under seat sealing areas.
- Compact Wafer Body: Space-saving, lightweight face-to-face structure allows quick installation and easy maintenance in crowded process lines.
- Bi-Directional / Uni-Directional Options: Engineered with resilient elastomeric seats for zero-leakage soft shut-off or metal seats for high-temperature and abrasive slurry service.
