Everlasting Valve process valves, bulk material valves, and diverter valves are put through the paces in chemical and petrochemical plants all over the world, where they make life easier for plant employees, reduce company costs, and boost production efficiency. These environments demand performance under high temperatures, frequent cycling, and abrasive media where conventional valves often fail.
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
Handles extreme abrasion: Rotating disc and self-lapping seat resist dust wear
Self-cleaning design: Prevents packing fouling from fine cement dust
Temperature and pressure resilience: Ideal for kiln and pre-heater environments
Low maintenance: Serviceable; long life in abrasive duty.
Proven reliability: Used for decades in cement, mining, and aggregate plants.
It’s all thanks to our innovative self-lapping, rotating-disc design, which works differently than the designs used in gate valves and ball valves. Because those other petrochemical valves open and close in the same place each time, they develop scratches and wear patterns that weaken their seals and cause costly leaks. Our process valves leverage a unique design that eliminates this problem while actually improving the valve’s performance over time. As the valves open and close, internal discs rotate incrementally and uniformly polish away scratches, creating an ever-tightening seal.
Thanks to this patented design, our valves are ideal for critical-sealing applications that demand exceptionally low-leak rates, and it’s why we can say with pride that our valves wear in while other valves wear out! In fact, the more demanding the application, the better our valves work. Think of your plant as a gym for our valves: with every repetition, they get stronger and tougher, handling operations like reactor loading and unloading, raw-material handling, and pneumatic conveying with extraordinary ease.
Our petrochemical valves reduce downtime, unplanned shutdowns, and maintenance costs while making your entire operation more efficient. What’s not to like? Even the cost is easy to swallow when you consider that using our valves will have a dramatic effect on your company’s bottom line. So, when you get tired of dealing with valves that can’t take the heat, kick ‘em out of the kitchen and bring in the big guns: Everlasting Valve process valves, bulk material valves and diverter-valves.

Our comprehensive service approach is designed to maximize equipment reliability, enhance operational efficiency, and reduce total cost of ownership.
These facilities handle high temperatures, corrosive chemicals, abrasive solids, and continuous cycling — all severe conditions for standard valve designs.
Rotating disc technology provides positive shut-off, self-cleaning action, and resistance to abrasion, corrosion, and heat. The valve seal improves with use rather than degrading.
Conveying, reactor feed and discharge, catalyst handling, and aggressive chemical processing lines including titanium dioxide, polysilicon's, molten sulfur, hydrogen sulfide, propylene, toluene, and more.
Yes. Self-lapping and self-cleaning surfaces greatly extend service life and reduce intervention frequency.
