A Round Knife Gate Valve is a standard-type isolation valve featuring a full circular through-bore,perfectly matching the size of conventional round industrial pipelines.It is specifically designed for on-off control and isolation of various media,including liquids,slurries,sewage,granular materials,and fluids containing fibers or suspended solids.With its simple structure,reliable performance,and wide adaptability,it has become one of the most commonly used valves in general industrial piping systems.

Working Principle

The round knife gate valve realizes full opening and full closing through the linear up-and-down movement of the circular knife gate,which is driven by optional manual,pneumatic,or electric actuators.The gate is designed with a sharp edge,which can effectively shear fibers,sundries,and solid particles in the medium during the closing process,preventing clogging and ensuring unobstructed flow of the medium.When fully open,the gate retracts completely into the valve bonnet,forming a full-bore flow channel with minimal flow resistance and no medium accumulation.

Key Features

-Full Circular Through-Bore:Consistent with standard round pipeline specifications,no flow dead ends,small flow resistance,and no medium deposition,ensuring smooth medium circulation.

-Superior Shearing&Anti-Clogging Performance:The gate is made of 304 or 316 stainless steel with a sharp edge,which can easily cut through fibers,impurities,and small lumps,making it ideal for harsh media such as sewage and slurry.

-Compact&Durable Structure:Simple and lightweight design,easy to install and maintain;the valve body is made of high-strength materials,with strong corrosion resistance and wear resistance,ensuring a long service life.

-Reliable Sealing Performance:Optional EPDM,NBR,PTFE soft seats or metal seats,which can achieve bubble-tight shutoff,effectively preventing medium leakage and ensuring the stability of the pipeline system.

-Multiple Drive Options:Available in manual,pneumatic,or electric drive modes to meet the needs of on-site operation,automatic control,and remote control,adapting to different industrial scenarios.
