Knife Gate Valve
A knife gate valve is a linear motion valve that uses a vertically moving blade to control fluid flow. 1 It's primarily used for on-off service, especially in applications with abrasive, corrosive, or high-solids content fluids. 2 The blade's sharp edge effectively cuts through these challenging media, minimizing blockage.
Knife gate valves are available in various configurations, including wafer, lugged, and flanged styles, and can be actuated manually, pneumatically, or hydraulically.
They find widespread use in industries such as mining, wastewater treatment, and chemical processing, where their robust design and ability to handle difficult fluids are highly valued. 4
Uni - Directional Knife Gate Valve
A Uni-Directional Knife Gate Valve is designed for flow control in one direction, typically used in applications where media should only flow in a specific direction to prevent damage or contamination. Featuring a sharp-edged gate, it cuts through thick slurries, sediments, and viscous fluids, ensuring a tight seal when closed while allowing for smooth operation in the open position.
This type of knife gate valve is commonly used in industries such as wastewater treatment, mining, and pulp and paper, where backflow prevention is crucial, and the handling of challenging materials is required.

Bi Directional Valve
A Bi-Directional Knife Gate Valve is designed to allow fluid or slurry flow in both directions, providing reliable sealing and control even in systems where flow direction can change. Featuring a sharp, flat gate that slices through thick, viscous, or abrasive media, it ensures a tight seal when closed, preventing leaks and backflow. Commonly used in industries like wastewater treatment, mining, and pulp and paper.
Bi-Directional Knife Gate Valves are ideal for applications where bidirectional flow is necessary, offering flexibility, durability, and effective flow control in demanding environments.

Bi Directional Valve
Slurry Valve
A Slurry Knife Gate Valve is specifically designed to handle abrasive, thick, and high-viscosity media, such as slurries, in industries like mining, wastewater treatment, and pulp and paper. It features a sharp, robust gate that slices through the slurry, providing a reliable seal when closed and ensuring minimal clogging or wear over time.
This valve is engineered for applications where reliable on/off control is essential, offering durability and resistance to wear in harsh environments where traditional valves may struggle to perform effectively.
