Pneumatic Actuation Rising Stem Flanged Round Port Heavy Slurry Knife Gate Valve

This high-performance knife gate valve is the definitive choice for automated, high-cycle isolation duties in the toughest environments. It is engineered specifically to handle heavy, high-concentration slurries, abrasive media, and fibrous materials that often challenge conventional valves.

Equipped with a robust Pneumatic Cylinder Actuator, it provides the necessary speed and power for demanding industrial processes. The Flanged connection ensures maximum structural integrity and a secure, high-pressure seal, while the Rising Stem offers clear visual feedback and easy automation integration.

Key Features & Automated Reliability

Feature Category	Technical Detail	Core Operational Benefit
Automation & Speed	Pneumatic Cylinder Actuator	Provides rapid, reliable automated on/off control, significantly increasing cycle speed and eliminating the need for manual labor in frequent-use applications.
Structural Integrity	Flanged Connection	Offers the highest connection strength and rigidity, ideal for large sizes, high pressure ratings, or systems subjected to vibration and stress.
Media Handling	Heavy Slurry Rated	Built with robust guides, thick resilient seats (or specialized materials like ceramic/UHMWPE), and a reinforced gate to effectively cut through dense, settled media.
Safety & Control	Rising Stem Design	The moving stem provides an unambiguous, immediate visual position indicator, and facilitates the straightforward mounting of limit switches for remote control feedback.
Flow Efficiency	Round Port Geometry	Ensures a full, unobstructed bore when open, minimizing fluid turbulence, head loss, and localized abrasive wear.
Non-Clogging	Bonnetless Design (Standard)	The simplified top structure (common in slurry KGV design) prevents solids from accumulating above the gate, ensuring consistent, jam-free cycling.
