Petroleum production is not a single valve problem. It is a connected operating environment — from wellhead flow and separation to produced water, solids removal, treatment, injection, and transfer. This page helps operators identify where severe service appears, what failure modes to watch, and where EV technology can reduce maintenance exposure.
Everlasting’s rotating-disc valve is purpose built for the harshest media and severe-service environments. Its self-cleaning, wear-in design maintains performance under extreme conditions, significantly reducing unplanned downtime, maintenance demands, and total cost of ownership.
Petroleum production operations expose valves to sand, produced water, brine, scale, pressure cycling, and multiphase flow. These conditions can turn small isolation, blowdown, drain, and transfer points into recurring maintenance problems when conventional valves leak, plug, erode, or fail to shut off.
Production streams often carry sand, fines, and solids that can erode valve internals, restrict movement, and shorten service life in separators, test lines, and blowdown points.
Produced water systems expose valves to solids, scale, chlorides, and corrosive media that can create leakage, buildup, and maintenance issues in transfer and disposal service.
Oil, gas, water, and entrained solids moving together create unstable service conditions that challenge shutoff performance, cycling reliability, and overall valve durability.
Scale, paraffin, and deposits can pack into critical sealing areas, reduce valve performance, and increase the risk of plugging or incomplete shutoff.
Petroleum production operations can involve frequent changes in pressure and flow that stress valves in wellhead, separator, injection, and process isolation duties.
Field locations need reliable valve solutions that reduce unplanned service, support longer run time and minimize maintenance exposure in hard-to-access areas.
Production facilities are asked to move more difficult fluids while protecting uptime, safety, and maintenance budgets. Valves see sand, scale, brine, produced water, emulsions, pressure cycling, temperature swings, and intermittent solids discharge. These conditions expose the weakness of conventional sealing surfaces.
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.

Our comprehensive service approach is designed to maximize equipment reliability, enhance operational efficiency, and reduce total cost of ownership.
Oil production include produced water which contain sand, scale, multiphase flow, corrosive fluids, and high pressure — all of which erode conventional valves.
The rotating disc design wipes solids from sealing surfaces, prevents buildup, and maintains low-leakage shut-off — even in sand-laden or multiphase service.
Produced water handling, separator isolation, heater treater drains, desalter service, and multiphase flow control.
Yes. Everlasting valves routinely outperform conventional ball and plug valves in erosive oilfields.
Longer service life, fewer change-outs, and reduced downtime deliver significant lifecycle cost savings
