Electric Actuated Knife Gate Valves, GGG40, DN300, PN10, Lug

Product Name: Electric Actuated Knife Gate Valves
Type: Unidirectional Knife Gate Valve
Body Material: Ductile Iron GGG40
Size: DN300, 12 Inch
Pressure: PN10, Class 150 LB
End Connection: Lug
Operation: Electric Actuator

The Knife Gate Valve is a unidirectional wafer valve designed for on-off operation in industrial pipelines. Its unique structure prevents clogging during shutoff when handling flow with particles. The beveled knife gate design enhances shear stress, ensuring smooth flow penetration.
