Cement plants operate in high-temperature, abrasive, and dusty environments, making valve selection critical for long-term reliability and
safety.
Key process stages include:
Across these stages, Everlasting’s rotating disc valves are ideal for handling abrasive powders, dense slurries, and hot air streams that quickly wear out conventional valves.
The Everlasting Diverters and BMV Valve Series are excellent in fly ash, Portland cement, kiln dust, alumina hydrate, alumina silica, calcined kaolin, sugar, titanium dioxide, ilmenite and rutile ores, pet coke, coal, catalyst and many other abrasives. Please request our booklet on the Everlasting Bulk Material Valves.
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
Cement production involves extremely abrasive powders, high temperatures, and continuous material handling. These conditions cause rapid wear in traditional valve designs.
Everlasting valves use a self-lapping rotating disc that resists abrasion, prevents powder buildup, and maintains tight shut-off. This delivers longer life and improved plant reliability.
Applications include raw mill feed, kiln systems, clinker handling, finish mills, silo diverters, and truck or rail loading systems.
Bulk Material Valves, Diverter Valves, and Process Valves are commonly applied throughout cement handling and process systems.
No. Their self-cleaning design prevents binding and seat damage, reducing maintenance intervals and downtime.
