Stainless steel knife gate valve is a heavy-duty industrial on-off valve specially designed for cutting off and controlling the flow of medium.Adopting full stainless steel material,it features corrosion resistance,high temperature resistance,wear resistance and sanitary performance.It is widely used in harsh working conditions with corrosive liquid,slurry,powder,dust and granular materials,realizing bubble-tight shutoff and stable long-term operation.

Main Structure&Material

Valve body,gate plate,bonnet:SS304/SS316 stainless steel,integral casting or forging,anti-rust and anti-corrosion.

Sealing seat:EPDM,NBR,PTFE or metal hard seal,suitable for low temperature,normal temperature and high temperature working conditions.

Stem:Stainless steel polished rod,with good straightness and wear resistance.

Connection type:Wafer,lug,flange end for flexible pipeline installation.

Core Features

Full stainless steel structure,excellent anti-corrosion&anti-rust performance,suitable for chemical,seawater and humid environments.

Thin knife-shaped gate cuts through slurry,fiber and granular media effectively,anti-blocking and self-cleaning.

Full bore design,small flow resistance,no material accumulation in the valve cavity.

Bidirectional sealing,bubble-tight shutoff,reliable isolation effect.

Compact structure,light weight,easy installation and low maintenance cost.

Available with manual,pneumatic,electric and hydraulic actuation modes.
