Knife Gate Valves

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 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.
