Australian valve is famous for Knife Gate Valve Valve supplier. A knife gate valve is a type of flow control valve used to control the flow of liquids or gases in a pipeline. It's specifically designed to handle applications involving slurries, viscous fluids, or materials that may contain suspended solids.

Working Principle:

·        Gate Mechanism: The valve consists of a gate or a blade that moves up and down or sideways to either permit or stop the flow of the substance.

·        Unobstructed Flow: When the valve is open, the gate retracts or lifts out of the path, allowing unimpeded flow.

·        Closure: Closing the valve involves lowering or sliding the gate into position across the flow path, effectively blocking the passage of the substance.


·        Flow Control: It regulates the flow of materials through a pipeline by either allowing or obstructing it.

·        Isolation: Knife gate valves are used to isolate sections of a pipeline, preventing the flow of material in certain directions.

·        Handling Thick Fluids: They are particularly useful for handling slurries, viscous fluids, and materials with suspended solids that might clog or obstruct other types of valves.

·        Bi-Directional Flow: Some knife gate valves can permit flow in both directions, providing versatility in various applications.

Knife gate valve supplier in Australia is preferred due to their capability to manage demanding materials that could potentially obstruct or harm other valve types. Their construction is tailored for robust industrial use, making them ideal for heavy-duty applications.
