Our KREBS® heavy-duty knife gate, check, and vacuum breaker valves deliver reliable performance while reducing CAPEX and maintenance-related costs. These valves are designed specifically for mineral processing applications to handle the most abrasive of slurries.
Our heavy-duty KREBS slurry valves are designed to facilitate quick field replacement, reducing plant downtime and capital costs by up to 45%. A standard universal frame across all valve models also allows easy actuator conversions.
Incorporating a range of standard wear components and materials, our valves are engineered and manufactured to create premium solutions with enhanced operating life. These wear components include composite cylinder housings to reduce corrosion, dust boots and stem covers for reliable actuation, and gate coatings for longer sleeve wear life. The inside cavity is also fully lined, so no slurry contacts the valve body, and is self-cleaning with each actuation.
We designed 90% of the components in our TG full-flanged series and TGW wafer series knife gate valves to be interchangeable. This reduces the number of replacement parts required onsite, saving costs and simplifying inventory management.
KREBS heavy-duty slurry valves are used in all mineral processing applications and across all process lines, from the comminution circuit to tailings. The comprehensive range includes full-flanged, wafer and high-pressure knife gate valves, vacuum breaker valves, and check valves.
Elastomers and gates are available in a variety of materials to accommodate specific application needs.
A full range of safety features are available, including gate guards to prevent pinch points, splash guards to collect discharge, and gate maintenance pins to assist during maintenance.
A full range of actuators – including pneumatic, hydraulic, bevel gear, hand wheel, chain-operated, and electric – is available to suit application needs.
Our pioneering service solutions include offsite maintenance and exchange solutions that reduce downtime and costs. We provide fully refurbished pumps, cyclones, and valves ready to replace existing equipment when needed. We’ll then take the worn part to one of our global service stations for rebuilding before returning to you to repeat the cycle. We also evaluate the worn equipment during servicing and provide recommendations to enhance service life. This ensures top-of-the-line service and reduces time onsite, mitigating the safety risks inherent to onsite maintenance.
