Lug Bonneted Manual Handwheel Round Port Knife Gate Valve
The Lug Bonneted Manual Handwheel Round Port Knife Gate Valve is designed for reliable shut-off and easy maintenance in demanding industrial applications.
It combines a lug-type body for flexible pipeline installation, a bonneted stem housing for improved sealing performance, and a round port design that ensures full flow and minimal pressure loss.
Ideal for slurry, wastewater, pulp & paper, and chemical processing, this valve provides long-lasting operation even under abrasive or corrosive conditions.
Key Features
Lug Type Body:
Threaded lugs allow easy installation and independent removal from either side of the pipeline—ideal for confined or fixed piping systems.Bonneted Construction:
Bolted bonnet protects the stem and packing chamber, minimizing leakage and extending the packing service life.Round Port Design:
Standard circular port matches conventional piping, ensuring smooth, unrestricted flow and reduced turbulence.Manual Handwheel Operation:
Simple, cost-effective control for on/off isolation. Optional pneumatic, electric, or hydraulic actuation is available for automation needs.Full-Bore Flow Path:
The knife gate completely withdraws when open, preventing media accumulation and ensuring low-pressure drop.Heavy-Duty Materials:
Available in ductile iron, carbon steel, or stainless steel to meet various process and environmental requirements.
