Product Name: Non-rising Stem Knife Gate Valve, Unidirectional
Body Material: ASTM A351 CF8
Size: DN100, 4 Inch
Pressure: Class 150 LB, PN10
End Connection: Wafer Type
Operation: Handwheel
The manual knife gate valve is a unidirectional, wafer-style knife-edge gate valve designed for on-off operation in industrial pipelines. The body and seat design prevent clogging during shutoff, even with fine particles in the flow. The beveled knife edge allows the gate to easily cut through thick media. Various types are available to suit different working conditions, including non-rising stem knife gate valves, wafer knife gate valves, lugged knife gate valves, pneumatic knife gate valves, electric knife gate valves, manual knife gate valves, and bevel gear knife gate valves.
