The KU-series manual knife gate valve is a unidirectional wafer-type valve designed for on-off operation in industrial pipelines. Its body and seat structure prevents clogging and ensures reliable shutoff when handling flow containing fine particles. The beveled knife edge allows the gate to cut through thick media with ease. Depending on the application, various configurations are available, 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.
