Through-Gate Knife Gate Valve KGT – Maximum Performance & Sealing
Flowrates through-gate knife gate valves are designed to ensure continuous flow with no turbulence or retention, delivering optimal performance on loaded, abrasive, and corrosive fluids. With a robust construction and high-precision machining, they guarantee perfect sealing and extended durability, even in the most demanding industrial environments.
High-Precision Design for Maximum Sealing
- Fully machined two-piece body – Ensures perfect flatness and reduces operating forces, extending the valve’s service life.
- Elimination of internal leakage – The body halves are precisely machined and sealed with an O-ring, preventing any fluid circulation between the two parts.
- Protected & replaceable seat – Each valve features a bolted retaining ring that secures the seat gasket, preventing dislodgment even with highly loaded fluids. Maintenance is greatly simplified as the seat can be replaced without complete valve disassembly.
- Available with a bonneted version: For the most sensitive applications where the fluid must not come into contact with the atmosphere.
Modularity and Durability in Harsh Environments
- Wide range of sealing materials – Elastomers, PTFE with dynamic seals, or metallic seats with compensation systems for tight shutoff, even at high temperatures and pressures.
- Simplified maintenance – Seat replacement can be performed without fully dismantling the valve, optimizing plant downtime.
Industrial Applications of the KGT Knife Gate Valve
Flowrates through-gate knife gate valves are installed across a wide range of industries that demand reliable, durable solutions for complex fluid control:
- Pulp & Paper Industry – Fiber management, steam circuits, and heavy effluents.
- Mining Industry – Abrasive slurry transport and tailings management.
- Chemical Industry – Aggressive fluids, filtration, and neutralization processes.
- Food Industry – Production processes requiring strict hygiene standards.
- Pumping Stations – High-pressure flow regulation and isolation.
