Square Knife Gate Valve is a special square-bore knife gate valve with a square flow passage,different from conventional round bore valves.It is designed for conveying bulk solids,powder,granular materials,ash,dust and slurry in square pipelines.

Working Principle

Driven by manual,pneumatic or electric actuator,the square knife gate moves up and down to fully open or fully close the square passage.The sharp gate edge can shear fibers,bulk materials and impurities,ensuring smooth flow and no material accumulation.

Key Features

Full square straight-through bore

No flow obstruction,no material retention,perfect for powder and granular material conveying.

Anti-blocking and shearing ability

Sharp stainless steel gate cuts debris,fibers and lump materials effectively.

Compact and rigid structure

High strength body adapts to heavy dust,abrasive and harsh working conditions.

Good sealing performance

Adopts elastic soft seat or metal seat,achieving tight shutoff under dust and slurry medium.

Multiple drive options

Available in manual,pneumatic,electric operation for automatic and remote control.
