Cast Iron / Ductile Iron Electric Actuation Wafer Round Port Heavy Slurry Knife Gate Valve

Automated, Cost-Effective Isolation for Dense Slurries

This Knife Gate Valve is the ideal solution for reliably automating isolation duties in heavy slurry applications where structural integrity and cost-efficiency are balanced. It is specifically designed to handle high-concentration, abrasive, or viscous media typically found in mining, wastewater, and general industrial processes.

The valve features a high-torque Electric Actuator for precise remote control and automated cycling, a durable Cast Iron or Ductile Iron body for structural strength, and a Wafer style body for space-saving installation. The heavy-duty design and Resilient Seat ensure maximum cutting force and reliable, tight shut-off against challenging media.

Key Features & Automated Slurry Performance

Feature Category	Technical Detail	Core Operational Benefit
Automation & Control	Electric Actuator (Multi-Turn)	Provides high-torque, precise remote control and accurate positioning, ideal for process sequencing and integration with DCS/PLC systems.
Media Handling	Heavy Slurry Rated	Equipped with thick, resilient seats (or specialized materials) and robust guides to effectively cut through and seal against dense, settled media.
Cost & Strength	Cast Iron / Ductile Iron Body	Offers a cost-effective solution with sufficient structural strength for standard heavy slurry pressure ratings (PN10/PN16).
Installation	Wafer Connection	Space-saving and lightweight design, fitting directly between pipeline flanges, simplifying installation in tight spaces.
Sealing Security	Resilient Seated Design	Provides guaranteed tight shut-off against media that often contains large particles or debris.
Design Reliability	Bonnetless Design (Standard)	Prevents solid particles from accumulating in the top structure, ensuring reliable, jam-free cycling even when handling viscous media.

Target Industry Applications

This valve is essential for automating heavy slurry processes in non-corrosive or mildly corrosive environments:

Mining & Mineral Processing: Automated control of tailing lines, low-concentration mineral slurry, and bulk material handling.
Wastewater Treatment: Automated isolation of raw sewage inflow, primary sludge, and dewatering feed lines.
Pulp & Paper: Automated isolation of low-density paper stock and fiber slurry lines.
Cement & Ash Handling: Automated isolation of fly ash and bottom ash slurry systems.

Customization: We offer optional hard-facing (e.g., hard chrome plating) on the gate for enhanced longevity, as well as specialized actuator enclosures (IP68) for submerged or extremely dusty conditions.
