Stafsjö‘s push through slurry valves covers several pressure classes making the range complete for both the concentrator plant and the tailing system.

The valves are modular designed and can easily be customized with actuators and related automation accessories to different process conditions. The compact slurry valve SLV is typically used in the sizing process on hydro cyclone clusters, as isolation valve around slurry pumps and tanks. As an option for applications with extreme solid content or severe wearing applications, especially within the primary grind circuit, we recommend the heavy duty SLF push through slurry knife gate valve.

For the tailing system and long distance pumping, the high pressure slurry valves SLH or SLX are normally required, which are available in pressure class up to 50 bar (725 psi).

The push through slurry knife gate valves provides superior flow characteristics, reliable and bi-directional shut-off performance in the most abrasive and demanding mineral processing applications.
