What’s one of the dirtiest, hottest, toughest, and roughest industrial-plant operations on the planet? If you work in the industry, you know that petroleum-refining business demands that its equipment handle high-temperature, high-pressure, abrasive conditions day and night, year after year.
Conventional metal-seated ball valves, globe valves, and gate valves struggle with erosion, coking, thermal stress, packing failure, and seat leakage.
Everlasting’s rotating-disc valve technology excels in these severe-service conditions because the disc continuously wipes clean, prevents buildup, and seals tighter over time, even under abrasive or sticky media.
It’s no wonder that major oil refineries have turned to Everlasting Valve Company again and again to solve their toughest plant problems. Our valves replace weaker metal-seated ball valves and other refinery valves that are doomed to have short lives and die rather undignified deaths when put to the test handling fluid-catalytic-cracker (FCC) units or continuous-catalytic reformers (CCRs). Tired of constantly replacing feeble, leaky refinery valves, petroleum refiners invited our rough-and-tough valves to pick up the slack and reinvigorate production efficiencies. Not only did our valves boost production, but they also dramatically reduced maintenance requirements and quickly had a positive impact on the refineries’ bottom lines. In fact, Everlasting valves have performed so well that United Oil Processing has mandated that only our valves be utilized in its refinery-production processes.
Refineries around the world have been depending on the unique features of the Everlasting self-lapping, rotating disc valve for years. From fresh-catalyst addition and slurry-pump isolation to off-gas cleanup and hot-catalyst withdrawal, Everlasting valves deliver the performance and longevity plants demand of them. Stop messing around with weak metal-seated ball valves and gate valves that constantly need replacing or require multiple redundancies to prevent unplanned outages. Switch to a refinery valve that can take your worst, prevent unexpected shutdowns, and come back for more, year after year!
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
Disc rotates every cycle, wiping away coke, catalyst, and solids
Proven in the harshest refinery services worldwide for decades
Extended performance, reduces maintenance and downtime
No cavities where solids or coke can accumulate
Handles sticky, abrasive, corrosive fluids better than ball/gate valves
Seat wears in, not out, creating long-term tight sealing
When you choose Everlasting Valve Company, you’re not just selecting a product—you’re gaining a partner dedicated to long-term performance and support. Our commitment to service extends far beyond standard maintenance or repair. It means timely access to our knowledgeable team of engineers and service professionals—ready to respond anytime, anywhere your operations demand.
At Everlasting, we pride ourselves on becoming an extension of your team. You can count on us to take ownership of every challenge and deliver practical, lasting solutions. When issues arise, our technical experts go beyond the symptoms to uncover the true cause. We evaluate your complete system to identify and resolve problems with precision and care.
Our comprehensive service approach is designed to maximize equipment reliability, enhance operational efficiency, and reduce total cost of ownership.
Refineries operate at high temperature and pressure with abrasive catalyst fines, coke, sticky residues, and corrosive fluids. Conventional valves suffer erosion, coking, and leakage.
Self-cleaning rotating discs continuously wipe coke and catalyst from sealing surfaces while self-lapping action tightens the seal over time.
FCC , reformer (Platformer & CycleMax),desulfurization, units, catalyst handling, HC / tower bottoms, slurry lines, off-gas systems, pump isolation, and equalization lines.
Yes. They can reliably handle resist coking, erosion, and thermal stress — extending run lengths and reducing unplanned shutdowns.
Extended service intervals and lower maintenance costs provide strong ROI in continuous refinery operations.
