Industrial knife gate valves are heavy-duty linear flow control valves engineered for isolation and on-off service in harsh industrial pipelines.They are specially designed for handling dust,powder,granules,slurry,fiber and corrosive media,featuring compact structure,full bore flow,anti-clogging performance and bubble-tight sealing.Widely adopted in dust removal,metallurgy,mining,chemical,water treatment and bulk material handling systems.

Key Construction

Valve body:Ductile iron,carbon steel,stainless steel 304/316

Gate blade:High-strength stainless steel,sharp-edged design to shear solid materials

Seal:EPDM,NBR,PTFE or metal seat for high temperature and abrasion conditions

Connection:Wafer,lug,flange end

Actuation:Manual,pneumatic,electric,gear operated

Main Features

Full bore design with minimal pressure drop and no medium accumulation.

Sharp knife gate cuts through dust,fibers and slurry to avoid blockage.

Bidirectional tight shutoff,suitable for positive and negative pressure pipelines.

Wear-resistant and corrosion-resistant,adapted to severe working conditions.

Simple structure,easy installation and low maintenance cost.

Compact size,saves installation space in complex piping systems.
