Electric Square Knife Gate Valve is a specially designed industrial shut-off valve with a square through-hole structure,driven by an electric actuator.It is mainly used for cutting off and controlling dusty gas,powder,granular materials,slurry and other mediums.With linear lifting and lowering of the knife gate,it realizes rapid opening and closing,self-cleaning and complete flow cut-off.It is widely applied in environmental dust removal,metallurgy,chemical industry,building materials,electric power,grain and bulk material conveying industries.

Main Features

Square full bore design,no flow dead angle,no material accumulation,ensuring smooth passing of granular and powdery media.

Equipped with electric actuator,supporting local manual operation and remote automatic control,convenient for centralized system management.

The knife gate has sharp shearing performance,which can cut off fibers,sundries and agglomerated materials to avoid valve jamming.

Compact structure,high overall rigidity,wear-resistant and corrosion-resistant valve plate,stable operation and long service life.

Optional soft seal and hard seal structure,realizing bidirectional sealing,good tightness and strong adaptability to harsh working conditions.

Dustproof,waterproof and explosion-proof electric actuator can be selected to meet different site safety requirements.
