Lug Bonneted Bevel Gear Round Port Knife Gate Valve
The Lug Bonneted Bevel Gear Round Port Knife Gate Valve is a heavy-duty isolation valve designed for reliable operation in pipelines carrying slurry, wastewater, pulp, or other viscous media.
It features a lug-type body for easy installation and maintenance, a bonneted stem housing for enhanced sealing performance, and a bevel gear mechanism that allows effortless operation of large-size valves.
The round port design ensures smooth flow with minimal pressure drop, making this valve ideal for demanding industrial environments where precision and durability matter.
Key Features
Bevel Gear Operation:
Equipped with a robust bevel gear operator to reduce manual effort and provide precise control, especially suitable for larger diameter or high-torque applications.Lug Type Body:
Threaded lugs allow secure, separate disassembly from either side of the pipeline without disturbing the opposite connection.Bonneted Construction:
Bolted bonnet protects the stem and packing from external contaminants, ensuring long-term sealing reliability.Round Port Design:
Circular flow path matches standard piping dimensions and minimizes flow resistance.Full-Bore Knife Gate:
The gate retracts completely out of the flow when open, preventing material buildup and ensuring unobstructed media passage.Rugged and Corrosion-Resistant:
Available in ductile iron, carbon steel, or stainless steel for a wide range of process conditions.
