Knife Edge Gate Valves: Engineering for the Toughest Media
A Knife Edge Gate Valve is specifically designed with a sharpened, beveled bottom edge on the gate. This "knife" profile allows the valve to slice through thick slurries, scale, and high-density solids that would typically prevent a standard valve from closing.
The FlowBiz Engineering Advantage
- Shearing Power: The precision-ground edge cuts through solids, ensuring the gate seats perfectly every time.
- Minimal Material Buildup: The slim, short-pattern design eliminates the deep "pockets" found in standard valves, preventing the accumulation of stagnant media.
- Bi-Directional and Uni-Directional Options: We offer both configurations to suit gravity-fed or pressurized systems.
- Self-Cleaning: As the gate closes, it pushes solids out of the seating area, maintaining its own sealing integrity.
Strategic Industrial Applications
1. Slurry and Abrasive Media
The primary choice for Mining, Cement, and Power Plants (Ash Handling). The KEGV is the only valve capable of handling heavy mineral slurries and abrasive grit without rapid internal erosion.
2. Pulp and Paper Processing
In the paper industry, "stock" is highly fibrous. FlowBiz Knife Edge valves slice through the fibers to prevent clogs, ensuring continuous production in pulp mills.
3. Bulk Solids and Powder Handling
Ideal for Food Processing, Pharmaceuticals, and Plastics. The design prevents granular materials like grain, pellets, or powders from settling in the seat, ensuring a smooth, unobstructed discharge from silos and hoppers.
4. High-Pressure & High-Temperature Service
Engineered for severe conditions, our forged and cast KEGVs provide a dependable shut-off in high-thermal environments where seat expansion must be managed precisely.
