Manual Knife Gate Valve

Manual knife gate valve is a type of on-off industrial valve operated by handwheel or hand lever.It adopts a slim gate with a sharp cutting edge,specially developed for cutting off fibrous,granular,viscous and slurry media.

This valve features a full bore straight flow channel,low flow resistance and no material accumulation when fully open.The sharp gate blade can shear fibers,sludge and sundries effectively,preventing pipeline clogging and ensuring tight shut-off in harsh working conditions.

With compact structure,short face-to-face dimension and light weight,the manual knife gate valve saves installation space and is easy to install and maintain.Common connection types include wafer,flanged and lug type to match different pipeline systems.

Simple manual operation makes it reliable and cost-effective without complex electric or pneumatic accessories.It is widely used in sewage treatment,papermaking,mining,chemical,power,metallurgy and building materials industries for media such as sludge,pulp,coal ash,tailings and mixed solid-liquid fluids.

Designed for fully open and fully closed working conditions,it is an economical and practical solution for manual pipeline isolation and medium cut-off.
