Knife edge gate valves are a type of industrial valve designed for on-off isolation services in applications where the flow of abrasive, viscous, or highly contaminated fluids needs to be controlled. These valves are specially engineered to handle challenging conditions, making them an excellent choice in industries such as pulp and paper, wastewater treatment, mining, power generation, and more. Knife edge gate valves operate by moving the gate up and down within the valve body. When the gate is raised, it creates an unobstructed flow path, allowing the fluid or slurry to pass through. Lowering the gate forms a seal against the valve seat, cutting off the flow.

Metal-seated sluice/gate valves are a type of industrial valve designed for controlling the flow of liquids in pipelines. These valves are characterized by a rugged and robust construction, making them suitable for a wide range of applications, including water supply and distribution, wastewater treatment, power generation, and various industrial processes.

A resilient seated sluice valve, also known as a resilient wedge gate valve or simply a resilient gate valve, is a type of industrial valve designed for controlling the flow of fluids in a pipeline, particularly for applications where a tight shut-off is required. It is characterized by its unique design, which includes a flexible rubber or elastomeric seat in the shape of a wedge that offers excellent sealing capabilities, making it a preferred choice for many water and wastewater systems, as well as in various industrial settings.
