Knife Gate Valve

A knife gate valve is a specialized linear motion on-off valve designed for handling challenging working conditions with slurry,solid particles,fibers,high-viscosity fluids and corrosive media.Featuring a sharp-edged thin gate plate,it is engineered to cut through stringy materials,sediments and debris tightly,achieving reliable isolation and cut-off in harsh pipelines.

With a full bore straight-through flow design,the knife gate valve presents minimal flow resistance when fully open,ensuring smooth medium transportation without pipeline blockage.Its compact short-structure design saves installation space and reduces overall equipment weight,making it easy for on-site assembly and pipeline layout.This valve is mainly used for full opening or full closing service,and is not suitable for flow throttling operation.

It is available in multiple connection types including wafer,flanged and lug type,with diverse driving options such as manual,pneumatic,electric and hydraulic operation to meet automatic control and remote operation demands.Sealing forms are divided into soft seal and metal hard seal:soft seal provides excellent tightness for conventional slurry conditions,while hard seal adapts to high temperature,high pressure and abrasive working scenarios.

Widely applied in sewage treatment,environmental protection,mining,metallurgy,papermaking,chemical industry,power plants and building materials industries,it is an ideal pipeline control solution for media like sludge,pulp,tailings,coal ash,crystal liquid and mixed solid-liquid flow.Simple structure,convenient maintenance and cost-effective performance make the knife gate valve a core component for industrial harsh medium conveying systems.
