Mining and mineral processing operations generate abrasive, erosive, and high-solid content media — including slurries, concentrates, tailings, and process water. Systems frequently handle rock dust, sand, lime, and metallic particulates under high pressure and temperature.
Key challenges include conventional gate or ball valves quickly failing due to packing wear, seat erosion, and clogging.
Everlasting’s rotating-disc valve design self-cleans, seals tighter over time, and operates reliably under severe service conditions.
Movement drives rotation providing self-lapping to enhance performance and extended life.
Positive Shut-off: Leak rates are less than industry standard ANSI B.16.34; MSS-SP61 for metal seated valves.
The spring-loaded disc is held firmly against the path that it travels.
Self-lapping disc ensures positive shut-off
Shearing action wipes media away to seal
Valve body design creates a vortex, self-cleaning
Disc pressure ensures positive seal
Value bodies are available in a wide choice of materials
EV Valves may be used for converging applications
Self-lapping disc design
Everlasting Valves are designed for the most severe applications
Engineered for Abrasion: Rotating disc removes buildup and protects sealing surfaces
Maintenance-Friendly: Dynamic spring-loaded packing can be adjusted or serviced
Longevity: Outlasts knife gate, plug, and pinch valves by multiples in abrasive duty
Proven Field Use: Deployed in mining, minerals, and cement industries worldwide for over 50 years

Slurries, tailings, concentrates, rock dust, and metallic particulates cause extreme abrasion and erosion that destroy conventional valves.
Rotating disc technology shears abrasive media from sealing surfaces, distributes wear evenly, and maintains tight shut-off under high-solids flow.
Slurry transport, tailings lines, ore concentrate circuits, grinding mills, dust collection, and pneumatic conveying of solids.
Yes. In abrasive slurry and powder conveying service, Everlasting valves routinely achieve multiples of conventional valve service life.
Reduced binding, wear, and reliable sealing minimize unplanned downtime and valve change-outs.
