Square Knife Gate Valve

The square knife gate valve is a special-shaped industrial isolation valve with a square flow passage,different from conventional round bore knife gate valves.It is professionally designed for rectangular pipelines,bulk material conveying and large-flow solid-liquid mixed media.

Built with a sharp cutting-edge gate plate,it efficiently shears fibers,debris,sludge and granular materials to prevent jamming and blockage.The integrated square straight-through channel ensures unobstructed flow,no material accumulation and low fluid resistance,which is ideal for bulk powder,ash,slag and slurry delivery systems.

It features a rigid one-piece body,compact structure and high structural strength to withstand harsh abrasive and corrosive working environments.Multiple operation modes are optional,including manual,pneumatic and electric,to meet on-site manual switching and automatic remote control demands.Flexible sealing solutions with soft seal and metal hard seal are available for different temperature,pressure and wear-resistant requirements.

Mainly supplied with flanged and wafer connection,this square knife gate valve is easy to install,dismantle and maintain.It is widely applied in environmental protection,waste water treatment,power plants,metallurgy,mining,building materials and chemical industries,especially suitable for square duct pipelines,dust removal systems and industrial solid waste discharge pipelines.
