Brandoni Knife Gate Valves are designed for shut-off in systems handling slurries, viscous fluids, powders, or solid-laden media. They are ideal for wastewater, mining, pulp & paper, and bulk material applications.

Unidirectional valves seal in one flow direction only, while bi-directional valves can isolate flow from either direction. Brandoni offers both types to suit different system designs.

The 18 Series is Brandoni’s bi-directional knife gate valve, offering dual sealing for flow in both directions.

The 19 Series and 19E Series are unidirectional, designed for one-way flow with a robust sealing system to prevent backflow.

Yes, they are built to withstand abrasive and high-solid content media. The sharpened gate design slices through tough materials with minimal wear.

Common materials include ductile iron and cast iron, with stainless steel gates and optional seat materials like EPDM or metal.

Yes, depending on the model and configuration, these valves can be used in exposed or buried service with appropriate stem extensions or protective coatings.

Absolutely. Brandoni Knife Gate Valves can be operated manually or fitted with pneumatic or electric actuators for remote control.

Most models feature wafer-style bodies for compact flange mounting, but custom configurations may be available on request.

Maintenance is minimal but should include regular inspection of the gate, seat, and packing. Many parts are replaceable to extend service life.

Knife gate valves are generally not WRAS-approved as they are not commonly used in potable water applications. Always confirm based on model and use case.

Industries include wastewater treatment, pulp and paper, mining, chemical processing, food waste handling, and general industrial applications where solids are present in the flow.
