Pneumatic Round Port Bonnetless Heavy Slurry Knife Gate Valve
This high-performance Knife Gate Valve is the ideal choice for applications demanding fast, automated, and frequent isolation of abrasive, high-density slurries and viscous media. Equipped with a robust Pneumatic Cylinder Actuator, it provides the necessary speed and thrust for demanding industrial automation cycles.
The combination of the anti-clogging Bonnetless design and Heavy Slurry rating ensures the valve cycles reliably, cutting through dense media every time without jamming, making it essential for process efficiency and safety.
Performance & Automation Highlights
| Feature Category | Technical Detail | Core Operational Benefit |
| Actuation | Pneumatic Cylinder | Provides rapid, reliable automated on/off control, significantly increasing cycle speed and eliminating the need for manual intervention. |
| Flow Management | Round Port Geometry | Ensures a full, unobstructed bore when open, minimizing friction and wear from abrasive particles while maintaining maximum flow capacity. |
| Slurry Reliability | Bonnetless Design | Guarantees non-clogging operation by eliminating the internal cavity where solids, grit, and fibers typically accumulate and prevent gate closure. |
| Safety & Feedback | Rising Stem Design | The valve stem moves vertically, allowing for easy installation of limit switches and providing a clear external visual indication of the valve’s position (essential for remote monitoring). |
| Durability | Heavy Slurry Rated | Built with reinforced materials and a precision-beveled gate edge to withstand high shear forces required to cut through static, concentrated media columns. |
