Since 1906, EV is the industry benchmark for reliability, tight shutoff, and extended operating life in high-pressure steam systems.
Continuously renews sealing surfaces during operation
Minimizing leakage, and improving operational reliability
Lowest lifecycle-cost solutions in the industry
Cement, mining, ash handling, refining, and power generation demand valves that survive severe wear.
Engineered for severe-service applications
Wide range of sizes, classes, and end connections
The patented rotating-disc and self-lapping seat design
Built to keep abrasive cement dust, clinker fines, and dry bulk solids moving while reducing plugging, erosion, and unplanned valve maintenance.
Cement operations generate abrasive kiln dust, clinker fines, and dry bulk solids that plug, erode, and destroy traditional valves.
Proven valve performance for refinery severe service where catalyst, coke, heat, and abrasive solids demand self-cleaning, long-life shutoff technology.
Self-cleaning rotating disc removes catalyst buildup
No cavities for coke accumulation
Handles continuous abrasion and thermal cycling
Proven performance in severe refinery applications
Engineered for ash handling, baghouse, economizer, and boiler-related systems where abrasive particulate and cycling create persistent valve failures.
Fly ash, bottom ash, and dust-heavy systems create severe erosion and plugging conditions throughout power generation facilities.
Ball valves trap ash and abrasive particulate
Gate valves erode quickly in ash systems
Dust buildup causes leakage and sticking
Frequent rebuilds increase outage costs
Reliable severe-service valve technology for produced sand, solids, separation systems, and erosive blowdown applications in upstream production.
Produced sand, solids, hydro-cyclones, and separator systems create erosive conditions that cause rapid valve wear and leakage.
Self-cleaning disc clears solids during operation
No cavities for sand accumulation
Handles continuous erosion and abrasive flow
Reliable shutoff in solids-heavy production systems
Designed for severe chemical processing applications where powders, corrosive media, fines, and high-temperature solids challenge conventional valve reliability.
Chemical processes involve corrosive media, powders, pellets, fines, and high-temperature solids that damage conventional valve internals.
Severe-service valve solutions for gasification, lockhopper, char, reactor, and catalyst slurry systems exposed to heat, solids, abrasion, and thermal cycling.
Synthetic fuels operations involve hot solids, gasification, biomass char, catalyst slurry, and lockhopper cycling that rapidly destroy conventional valves.
Self-cleaning disc clears solids continuously
No cavities for char accumulation
Handles continuous abrasion and thermal cycling
Reliable performance in gasification and lockhopper systems
Purpose-built for abrasive slurry, mineral solids, dust-heavy service, and high-solids isolation where traditional valves wear out or fail to seal.
Mining systems handle abrasive slurry, high solids loading, corrosive process streams, and dust-heavy service that rapidly destroys traditional valves.
Engineered for demanding boiler blowdown environments where flashing flow, thermal cycling, and high-frequency operation quickly destroy conventional valves.
Boiler blowdown systems operate under extreme thermal cycling, flashing, high velocity flow, and erosive conditions that rapidly damage conventional valve designs.
Built for abrasive, high-cycle, and solids-laden service where conventional valve designs often require frequent replacement.
Self-cleaning disc action and open-body design help reduce buildup-related failures and service interruptions.
When replacements, maintenance labor, and downtime are included, EV can materially reduce total cost of ownership.
Typical savings based on customer feedback and representative applications. Actual results may vary by operating conditions, media, valve size, cycle frequency, installation, maintenance practices, and downtime cost assumptions. Estimates are not a guarantee of performance, savings, service life, or total cost reduction.
Best for: High-cycle boiler blowdown and flashing service
Positioning: Replaces conventional blowdown valve designs in severe service
Best for: Solids-laden and erosive process flow applications
Positioning: Alternative to ball, gate, and plug valves
Best for: Dry bulk solids, dust, and conveying systems
Positioning: Used where plugging and abrasion are common
For high-downtime applications, repeated rebuilds and lost production can exceed first valve cost many times over.
| 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. |

Actual costs, savings, and performance may vary by application, operating conditions, maintenance practices, and site-specific factors. Results are not a guarantee of performance, savings, payback, or return on investment.
The model estimates replacement events per year using the current valve life, then applies downtime and maintenance cost to each event. EV performance is modeled using a configurable lifecycle multiplier and EV valve price.
All total cost of ownership, cost avoidance, downtime reduction, maintenance savings, lifecycle cost, payback period, and ROI values generated by this tool are estimates only. These calculations are based on information entered by the user, published or assumed cost factors, and generalized performance assumptions.
Everlasting Valve Company makes no representation, warranty, or guarantee, express or implied, regarding the accuracy, completeness, reliability, or applicability of the results to any particular facility, process, or application. Actual costs and savings may differ materially due to variables including, but not limited to, process conditions, abrasive or corrosive media, operating pressure and temperature, valve cycling frequency, installation conditions, maintenance intervals, labor rates, outage costs, replacement part costs, and equipment selection.
The results should not be relied upon as engineering advice, financial advice, procurement justification, or a guarantee of product performance. Final product selection and economic evaluation should be reviewed by qualified personnel.
The accuracy of the calculation depends on the accuracy and completeness of the information provided by the user. Everlasting Valve Company is not responsible for incorrect, incomplete, outdated, or site-specific assumptions entered into the calculator.
Engineering Review Recommended
Valve selection and lifecycle cost analysis should be reviewed by qualified engineering and maintenance personnel. Severe-service applications may require additional review of media characteristics, pressure, temperature, materials of construction, actuation requirements, and installation conditions.
