Round Knife Gate Valve

The round knife gate valve is a classic industrial on-off valve with a standard round flow passage,which is the most widely used type in knife gate valve series.It is specially designed for circular pipelines,suitable for cutting off and isolating various harsh media such as slurry,solid particles,fibers and high-viscosity fluids.

Equipped with a sharp-edged thin gate plate,this valve can effectively shear fibrous substances,sludge,sediments and granular materials during the closing process,avoiding pipeline blockage and ensuring tight shut-off.Its full-bore round straight-through structure ensures minimal flow resistance when fully open,no material accumulation in the flow passage,and smooth transportation of media without additional pressure loss.

It has a compact and reasonable structure,short face-to-face dimension,light weight and easy installation,which can be perfectly matched with most standard circular pipelines.Multiple operation modes are optional,including manual,pneumatic and electric,to meet different on-site operation needs such as manual switching,automatic control and remote operation.Both soft seal(rubber,PTFE)and metal hard seal options are available,adapting to different working conditions such as normal temperature,high temperature,corrosion and abrasion.

Common connection types include wafer,flanged and lug type,which are widely used in sewage treatment,mining,metallurgy,papermaking,chemical industry,power plants,building materials and other industries.It is an economical and reliable pipeline control solution for media such as sludge,pulp,tailings,coal ash,fly ash and solid-liquid mixed fluids,and is the preferred valve type for conventional circular pipeline systems.
