Self-Cleaning Action
Rotating motion helps clear particles from the seating surfaces.
Common valve failures often point back to the same root causes: buildup, erosion, leakage, high torque, and premature wear. This comparison highlights how conventional valve designs can struggle in severe-service applications and how EV’s rotating-disc technology helps address those failure modes through self-cleaning action, self-lapping sealing surfaces, and a design built for demanding media.
| Conventional Valve Designs | Typical Failure in Severe Service | How EV Helps |
|---|---|---|
| Ball Valves | Solids pack around the ball, damaging seats and creating leakage paths. | EV rotating-disc technology helps wipe and renew the sealing surfaces. |
| Gate Valves | Abrasive media erodes gates and seats, especially in ash, sand, slurry, and dust service. | EV metal-seated design is engineered for abrasive and erosive service. |
| Plug Valves | Material buildup increases torque, causes sticking, and reduces shutoff performance. | EV self-cleaning action supports reliable cycling in dirty applications. |
| Knife Gate Valves | Seat damage and leakage are common in high-cycle or abrasive applications. | EV is designed for applications where shutoff reliability and service life matter. |
| Butterfly Valves | Discs and soft seats erode in high-temperature or abrasive flow. | EV severe-service construction fits harsher process environments. |
Everlasting Valve introduced the original self-lapping, rotating-disc valve to the world in 1906, and it’s been the gold standard for severe-service applications ever since.
Each time the disc rotates, it produces an action that renews and polishes the metal seating surfaces. As a result, each Everlasting Valve wears in with use in tough industrial applications—with each operation making the valve more efficient and producing a tighter seal—while all other valves wear out and ultimately fail.
Everlasting Valve’s rotating disc design is engineered to address the root causes of severe-service valve failure: buildup, abrasive wear, leakage, and unplanned downtime.
Rotating motion helps clear particles from the seating surfaces.
Designed to reduce pockets where material can accumulate.
Built for demanding temperature, pressure, and abrasive service.
Sealing surfaces renew through operation instead of rapidly degrading.
Reduces replacement frequency in applications that punish standard valves.
Reliable shutoff and reduced maintenance help keep processes online.
EV technology focuses on the causes of valve failure: buildup, abrasive wear, leakage, high cycling, and unplanned outages.

First manufactured in 1906 our original product, the boiler blowdown valve, which effectively clears sludge and other impurities formed during steam-boiler operation, is specifically designed for the harshest industrial applications. Traditionally used globe valves wear out quickly in industrial steam applications, as their operation forces dirt and scale into the valve seat, which prevents effective sealing, ultimately resulting in failure.
Everlasting Valve’s patented bulk material valves solve your toughest, dirtiest plant problems, effortlessly handling extremely abrasive, high-temperature, high-cycling applications. Built on our self-lapping, rotating-disc-valve technology, our bulk-material valve is hands-down the toughest, longest-lasting, best-performing bulk material on the market today.
Everlasting Valve Company’s process valves have decades of field-proven service in extreme environments, significantly outperforming ball valves by handling slurry, chemicals, heat, scale, and dry solids with exceptional ease. Give our process valves your worst: the toughest, dirtiest, hottest, most brutal applications are business as usual for our hard-wearing components.
Building on our revolutionary self-lapping, rotating disc-valve technology, our diverter valves, are, quite simply, the last valves you’ll ever need. Deployed in some of the harshest plant environments all over the world, our valves are still going strong decades after they were first installed. What makes Everlasting valves superior isn’t just the innovative design, however.
