Over the past decade, demand for ethylene has steadily risen and so has the need for valve solutions that offer maximum reliability, safety and performance.
Reliable valves and services for ethylene and propylene processing
After safety, uptime is the primary concern that ultimately determines whether or not an olefin plant will be sustainably profitable in an increasingly competitive global market.
There are many critical valves within an ethylene plant. From cracking to quenching, valves are subject to a wide range of thermal conditions, corrosive medium and coke residue. In these demanding applications, inferior valves will quickly wear, leak and need service. Great valves will reduce fugitive emissions and extend the intervals between scheduled maintenance shutdowns.
Ethylene-specific valves from Neles are tailor-made to tackle applications challenges
Neles offers a wide range of valves specifically designed to overcome the challenges of ethylene production including fuel gas control valves, shutoff valves and burner on-off valves. All are engineered and built with a focus on safety and uptime.
Ordinary seat and seals will not perform reliably in ethylene processing. That’s why Neles uses advanced seat materials and complimentary seat geometries proven to provide better upstream and downstream sealing, eliminate leaks, prevent buildup and increase cycle life while also lengthening intervals between scheduled maintenance.
Friction and galling are the enemy of valve cycle life. Our proprietary coatings are carefully chosen for their thermal expansion compatibility with the substrate. The result is that many Neles customers are now increasing the time between scheduled valve maintenance from 3 – 4 years to 7 – 9 years.
Trouble-free valves: Neles specialty for over 60 years
Neles has put 60 years of experience in the olefin industry into our full line of control, safety, and automated on/off valves. Our full-offering of the industry’s safest valves meet all the demands of ethylene processing to provide 7 to 9 years of uptime – compared to competitive valves that operate at roughly half that. We push the industry envelope in extending uptime and increasing ROI.
