Knife Gate Valves, widely used in industrial applications, are a type of flow control valve known for their unique design featuring a sharp-edged gate or blade that effectively slices through and controls the flow of abrasive and viscous fluids, making them ideal for challenging environments such as wastewater treatment, mining, and pulp and paper industries. These gate valves offer a tight shutoff to minimise leakage, come in various sizes to accommodate different pipe diameters, and are often made of materials like cast iron for durability and resistance to corrosion. Their ability to handle high-pressure systems and abrasive materials makes them a dependable choice for fluid control in demanding settings.

A Knife Gate Valve is a type of valve designed to control the flow of fluids in systems by using a sharp-edged gate to cut through and control the flow.

Knife Gate Valves are often used in industries such as wastewater treatment, mining, pulp and paper, and power generation for applications involving thick, viscous, or abrasive media.

Knife Gate Valves are distinct for their ability to cut through and isolate media effectively, making them suitable for applications with solid particles or slurries.

Yes, most Knife Gate Valves are bidirectional, meaning they can control the flow in both directions.

They use a sharp-edged gate that moves perpendicular to the flow path to control or block the media.

Yes, Knife Gate Valves are designed to handle abrasive and challenging media effectively, thanks to their robust construction.

Regular maintenance includes inspecting the seals, gate, and actuator, and ensuring they are free from debris to maintain optimal performance.

Yes, Knife Gate Valves come in various types, including through-going, wafer, and lugged designs, each suitable for specific applications.

Yes, Knife Gate Valves can be automated with actuators for remote operation and control.

Yes, Actuation Valve offers sustainable spares and replacement parts for ongoing maintenance schedules.

Knife Gate Valves offer benefits such as excellent sealing, minimal pressure drop, and the ability to handle tough media, making them ideal for demanding applications.
