Knife Gate Valves - AILAN Tech

About Our Knife Gate Valves

Our knife gate valves are specifically designed for applications involving abrasive slurries, viscous fluids, and other challenging media. They feature a sharpened blade that cuts through the media, providing excellent sealing performance even with fibrous or particulate-laden fluids.

Constructed from high-quality materials including ductile iron and stainless steel, our knife gate valves offer superior durability and corrosion resistance. They are widely used in industries such as mining, pulp and paper, chemical processing, and wastewater treatment.

Installation and Maintenance

Installation Guidelines

Ensure the valve is installed in the correct orientation with the flow direction arrow on the body.
The valve should be installed in a horizontal position with the stem vertical.
Before installation, clean the pipeline to remove any debris or foreign matter.
Use appropriate gaskets between flanges to ensure a proper seal.
Tighten flange bolts uniformly in a crisscross pattern to ensure even pressure.
Ensure there is sufficient space around the valve for operation and maintenance.
After installation, test the valve for leaks before putting it into service.

Maintenance Recommendations

Regularly inspect the valve for leaks, corrosion, or other damage.
Lubricate the stem and other moving parts periodically to ensure smooth operation.
Check the packing gland regularly and tighten if necessary to prevent leaks.
Keep the valve in either fully open or fully closed position when not in use for extended periods.
Clean the valve body and external parts regularly to prevent buildup of dirt and debris.
For valves in critical applications, consider implementing a preventive maintenance program.
If the valve is not operating properly, consult the technical manual or contact our support team.
