ASTM A216 WCB Knife Gate Valve, Carbon Steel, DN80, PN10, RS

Key Specifications / Features

The ASTM A216 WCB Knife Gate Valve from our supplier is a high-quality unidirectional valve designed for reliable performance. It features a rising stem mechanism and a robust cast carbon steel body, ensuring durability and strength. With a DN80 (3-inch) diameter and a pressure rating of PN10 (Class 150 LB), this valve is suitable for a variety of industrial applications. Available in lug or wafer configurations, it offers flexibility in installation.

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.
