Manage heavy-duty slurry and food-grade fluids with Ruisongbuild’s DN300 manual knife gate valves. Manufactured with a high-strength stainless steel gate and an epoxy-coated ductile iron/SS body, these valves are engineered to cut through viscous liquids, pulp, and powders. Supporting PN10/16/25 and ANSI 125/150 standards, our high-temperature resistant valves ensure a bubble-tight seal and zero-clog performance for water treatment, mining, and food processing infrastructure.
Description
Ruisongbuild DN300 Knife Gate Valve: Engineered for Clog-Free Control
In environments where standard gate valves fail due to sediment or fiber buildup, the Knife Gate Valve is the ultimate engineering solution. At Ruisongbuild, our DN300 (12-inch) series features a sharpened stainless steel blade designed to slice through thick slurries, waste water, and bulk solids. With a non-toxic epoxy coating and food-grade material options, this valve provides a safe and durable interface for both aggressive industrial and sensitive food-processing lines.
