Non-rising Stem Knife Gate Valve, ASTM A351 CF8, DN100, PN10

Key Specifications / Features

This Non-Rising Stem Knife Gate Valve features a robust ASTM A351 CF8 stainless steel body for excellent corrosion resistance. With a 4-inch size (DN100), Class 150 LB pressure rating, and PN10 compatibility, the wafer-type ends ensure easy installation between flanges, and the valve is operated manually using a handwheel for precise control.

The manual knife gate valve is a unidirectional, wafer-style knife-edge gate valve designed for on-off operation in industrial pipelines. The body and seat design prevent clogging during shutoff, even with fine particles in the flow. The beveled knife edge allows the gate to easily cut through thick media. Various types are available to suit different working conditions, 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.
