The KU Series Knife Gate Valve is a unidirectional wafer-type valve designed for on-off service in industrial pipelines. Its unique structure prevents clogging during shutoff when handling media containing particles. The beveled knife gate design delivers high shear force, enabling smooth penetration through the flow for reliable and efficient operation.

Product Features

» Cast-in guide claws at the port bottom secure the gate without a groove, preventing shutoff clogging and ensuring a tight seal. These claws push the gate toward the seat for optimal sealing in the closed position.
» Integral body design allows easy assembly and ensures zero shell leakage.
» Full-port configuration minimizes pressure drop and maximizes flow capacity.
» PTFE resilient points on the gate prevent metal-to-metal contact between the gate and body.
» Slim body and compact construction for easy installation.
» Beveled knife edge delivers strong cutting force and tight sealing.
» Optional increased gate thickness for higher pressure applications.
» Replaceable side-entry seat reduces maintenance costs.
» L-shaped seat retainer locks the seat into the valve body and shields the seat side from direct flow impact.
» Optional stem cover extends stem service life.
» Dual thrust bearings minimize operating torque.
» Grease nipple for easy bearing lubrication.
