Given the high pressures, velocities, and abrasive properties of tailing’s slurry during transportation and deposition, Isolation valve reliability can become a big problem for operators if the right valve technology is not utilized in these applications.

Historically, the Isolation of High-Pressure tailings has been trusted to discharging style Knifegate valves and in some cases the associated management of these excursions can be costly to ensure no harm is inflicted on personnel or the surrounding environment.

Emerson introduces the new Clarkson Severe Service KS1 & KS3 Severe Service Knifegate Valve which rests the bar for reliable zero leakage isolation in the industry
