Lug Bonneted Pneumatic Round Port Knife Gate Valve
The Lug Bonneted Pneumatic Round Port Knife Gate Valve is an automated valve solution designed for fast, reliable, and leak-free operation in demanding industrial systems.
Featuring a lug-type body, a bonneted stem protection design, and a round port for full-bore flow, this valve is ideal for handling slurries, wastewater, pulp, and chemical media.
The pneumatic actuator enables quick and efficient remote control, making it perfect for automation in continuous or high-cycle processes.
Key Features
Pneumatic Actuation:
Provides fast, consistent, and maintenance-free operation. Ideal for systems requiring frequent valve cycling or remote automation.Lug Type Body:
Includes threaded lugs for easy installation and independent removal from either side of the pipeline without disturbing adjacent connections.Bonneted Construction:
The bolted bonnet safeguards the stem and packing, preventing leakage and contamination for longer service life.Round Port Flow Path:
Circular port design ensures smooth, unobstructed flow and reduces turbulence and pressure loss.Full-Bore Knife Gate:
Gate fully retracts when open, allowing maximum flow capacity and preventing buildup of solids.Heavy-Duty Design:
Built from corrosion-resistant materials such as ductile iron, carbon steel, or stainless steel for dependable operation in harsh conditions.
