MANUAL KNIFE EDGE GATE VALVE WAFER LUG TYPE
“aline” Make Manual Knife Edge Gate Valve – Wafer Lug Type is specially designed for on-off isolation of abrasive, viscous, slurry, powder, and solid-laden media in demanding industrial applications. Featuring a precision-machined knife-edge gate, the valve easily cuts through thick fluids and suspended solids, ensuring reliable shut-off with minimal pressure drop. The lug-type wafer design allows secure installation between flanges and supports dead-end service, making it ideal for heavy-duty process industries.
Manufactured from high-quality Cast Iron, Ductile Iron, Carbon Steel, Stainless Steel, or fabricated materials, the ALINE Knife Edge Gate Valve provides excellent corrosion resistance, durability, and long service life. Its non-rising stem and smooth handwheel operation ensure easy manual operation while maintaining dependable sealing performance even under harsh operating conditions.
ALINE Manual Knife Edge Gate Valves are widely used in Pulp & Paper Industries, Mining, Cement Plants, Power Plants, Wastewater Treatment, Chemical Processing, Sugar Industries, Food Processing, Bulk Material Handling, Steel Plants, Ash Handling Systems, Slurry Pipelines, and General Industrial Applications where reliable isolation of difficult media is required.
Designed for maximum reliability and low maintenance, ALINE Knife Edge Gate Valves deliver outstanding performance in the most demanding industrial environments.
