Knife Gate Valve
150 products found
A knife gate valve is a lightweight, linear-motion isolation valve featuring a sharpened stainless steel plate designed to slice cleanly through thick slurries, wastewater, and suspended solids. Engineered with a smooth, full bore that ensures zero pressure drop and permits pipeline pigging, its planar "knife" edge cuts through packed debris to compress tightly against a resilient or flexible metal seat for a reliable, bubble-tight seal. Operating as an on/off valve via manual, pneumatic, or electric actuation, this highly cost-effective design is an industry standard for pulp, paper, and sewage treatment systems. As a premier platform of China knife gate valve manufacturers, we supply compact knife gate valves in sizes from DN50 to DN1000, using robust cast or fabricated alloys to ensure smooth operation and low maintenance for demanding, low-pressure utility lines globally.
