Unidirectional Knife Gate Valve, GGG40, PN10, Non-rising Stem

Product Name: Unidirectional Knife Gate Valve, Non-rising Stem
Body Material: Ductile Iron GGG40
Pressure: PN10, Class 150 LB
End Connection: Wafer Type
Operation: Handwheel

The manual knife gate valve is a unidirectional wafer-type valve used for on-off operation in industrial pipelines. The valve's 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. Depending on the working situation, the following types are available: non-rising stem knife gate valve, wafer knife gate valve, lugged knife gate valve, pneumatic knife gate valve, electric knife gate valve, manual knife gate valve, and bevel gear knife gate valve.
