ASTM A351 CF8M Knife Gate Valve, DN600, PN10, Unidirectional

Product Name: Non-rising Stem Knife Gate Valve, Unidirectional
Body Material: ASTM A351 CF8M
Size: DN600, 24 Inch
Pressure: PN10, Class 150 LB
End Connection: Wafer Type
Operation: Handwheel

The KN-series manual knife gate valve is a unidirectional wafer knife-edge gate valve designed for on-off operation in industrial pipelines. Its innovative body and seat structure effectively prevent clogging and ensure reliable shutoff in applications with fine particles. The beveled knife edge allows the gate to easily cut through thick or abrasive media. Various configurations are available to suit different operational needs, including non-rising stem, wafer, lugged, pneumatic, electric, manual, and bevel gear knife gate valves.
