Valves for ethylene and propylene processing
Improving reliability and productivity of your process
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
Sustainable profitability
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
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.
Valves, pumps and services
Pinch valves
Flowrox™ pinch valves can be either used for shut off, also known as isolation, or control. Every Flowrox pinch valve is fit for the most demanding applications in which conventional valves encounter problems with wear due to increased turbulence.
Flowrox™ industrial pumps
Flowrox™ industrial pumps serve a wide range of process industries. Peristaltic hose pumps and progressive cavity pumps are specifically designed for demanding processes involving abrasive, corrosive, highly viscous or crystallizing media with high solids content.

Making a big difference to ethylene project engineering
As demand for ethylene rises, so does the need for valve solutions that offer maximum reliability, safety and performance. After safety, uptime is a major determinant of whether an ethylene plant can be sustainably profitable in an increasingly competitive global market.
Selecting valves for an ethylene plant: what is the right choice?
Running a reliable and competitive ethylene plant in an ever-growing ethylene production market is a matter of overcoming many challenges. However, choosing valve solutions that offer maximum reliability, safety and performance for your application is the first step to success.
Flow control solutions for ethylene cracker furnaces
This is Part 1 of our series of three posts on valve selection for ethylene cracking. Ethylene is a basic building block in the chemical industry, and is the link between chemical companies and petroleum refiners. An ethylene plant, also well known as a steam cracker, is often and correctly called an olefin plant because of the fact that the end products are primarily olefins, mainly ethylene, propylene and butadiene.
