The KU-series manual knife gate valve is a unidirectional wafer-type valve designed for on-off service in industrial pipelines. Its body and seat structure prevent clogging, ensuring reliable shutoff even with media containing fine particles. The beveled knife edge allows the gate to cut through thick media with ease. Depending on application requirements, various configurations are available, including non-rising stem, wafer, lugged, pneumatic, electric, manual, and bevel gear-operated knife gate valves.
