The Stainless Steel Manual Lug Knife Gate Valve is a corrosion-resistant isolation valve designed for abrasive and corrosive slurries. Its SS304 (CF8) or SS316 (CF8M) body provides maximum chemical longevity, while the Lug-style design enables secure bolting and dead-end service. Operated by a manual handwheel, its sharp, beveled gate slices through solids and fibers, ensuring a tight seal in chemical processing, paper pulp, and wastewater applications.
