Carbon Steel Knife Gate Valve, WCB, DN150, PN10, Pneumatic

Key Specifications / Features

The Carbon Steel Knife Gate Valve Factory produces high-quality unidirectional knife gate valves designed for reliable flow control in various industrial applications. These valves feature an ASTM A216 WCB body, ensuring strength and durability. With a DN150 (6-inch) size and a PN10 pressure rating, they are suitable for medium-pressure environments. Available with lug or wafer ends for versatile installation options, these valves are pneumatically actuated for efficient and precise operation.

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

Product features

» Cast-in guide claws at the port bottom secure the gate without a groove, preventing shutoff clogging and ensuring a tight seal. The guide claws push the gate toward the seat for optimal sealing in the closed position.
» Integral body design allows easy assembly and guarantees zero shell leakage.
» Full-port design reduces pressure drop and maximizes flow capacity.
» PTFE resilient points against the gate prevent metal-to-metal contact between gate and body.
» Slim body and compact construction enable easy installation.
» Beveled knife edge provides high cutting force and tight sealing.
» Optional increased gate thickness to handle 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.
» Two thrust bearings reduce operating torque.
» Grease nipple for easy bearing lubrication.
