Body Material: ASTM A351 CF8
Size: DN250, 10 Inch
Pressure: PN10, Class 150 LB
End Connection: Lug
Operation: Handwheel

The manual knife gate valve is a unidirectional wafer knife edge valve designed for on-off operation in industrial pipelines. Its body and seat structure prevent clogging during shutoff, making it ideal for handling media with fine particles. The beveled knife edge allows the gate to cut through thick media with ease. The valve is available in various configurations to suit different working conditions, including non-rising stem, wafer, lugged, pneumatic, electric, manual, and bevel gear knife gate valves.
