Rising Stem Knife Gate Valve, A351 CF8M, DN100, PN10, 4 Inch

Key Specifications / Features

The Rising Stem Knife Gate Valve, manufactured with an ASTM A351 CF8M body, features a 4-inch (DN100) size and is rated for PN10 pressure class and Class 150 LB. Designed for unidirectional flow, this valve has wafer ends for easy installation and is handwheel operated for smooth and reliable control.

The manual knife gate valve is a unidirectional wafer knife edge gate valve designed for on-off operations in industrial pipelines. Its body and seat structure prevents clogging, ensuring reliable shutoff even with fine particles in the flow. The beveled knife edge allows the gate to easily cut through thick media. To meet various working conditions, the following types of knife gate valves 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
» Bevel gear knife gate valve
