ASTM A216 WCB Knife Gate Valve, DN150, PN16, Unidirectional

Key Specifications / Features

The ASTM A216 WCB Knife Gate Valve features a carbon steel body and is designed for robust performance in various industrial applications. Rated DN150 (6 inches), Class 150 LB, PN16, it includes wafer ends and a rising stem for easy visual indication of valve position. The unidirectional flow design ensures reliable shut-off and efficient operation in both liquid and slurry handling systems.

The manual knife gate valve is a one-way valve designed for on-off operation in industrial pipelines. Its body and seat structure prevent clogging during flow, even when handling fine particles. The beveled knife edge helps the gate easily cut through thick media. Depending on the application, various types are available, including non-rising stem, wafer, lugged, pneumatic, electric, manual, and bevel gear knife gate valves.
