Knife Gate Valves

The Knife Gate Valve is specifically designed for on/off isolation in applications involving slurry, viscous, abrasive, or solid-laden media. Its sharp-edged gate allows it to easily cut through thick fluids and suspended solids, ensuring smooth operation even in challenging conditions.

These valves are widely used in industries such as water treatment, chemical processing, mining, pulp & paper, and food processing, where handling difficult media is essential. With a simple design and lightweight construction, knife gate valves offer low pressure drop, easy operation, and cost-effective performance.

As per the catalogue (page 7), these valves are available in uni-directional, bi-directional, and heavy-duty designs, with multiple actuation options including manual, pneumatic, and electric systems
