Finding the benefits of unified valve automation

The benefits that come from selecting Neles valve automation components for your automated valves makes perfect sense. Our devices deliver safe and reliable performance, they provide a competitive total cost of ownership (TCO) across their entire lifecycle.

Valve controller usability saves money and time, while improving safety and reliability

At a plant, the usability of a valve controller plays a major role in a number of situations. Whether you need to install a valve controller on actuators in volume production, quickly replace one in real field conditions or interpret its diagnostic information – simplicity is highly beneficial.

Upgrading FCC-unit valve controllers without disruption

In the fluid catalytic cracking (FCC) unit of a large refinery built in the 1940s in the US, a variety of control valve types and brands, along with their proprietary valve controllers, had been installed over the years. This had led to production inconsistency and disruption. The unit wanted to have one type of controller with multiple bracket designs to fit the wide variety of valves in the plant.

Using digitalization to boost efficiency

As a valve manufacturer, Neles’ goal is to meet the customer’s current and future expectations. Those expectations, are often focused on getting the maximum availability out of their valves and systems. That’s why Neles can supply not just products, such as control valves, actuators and positioners, but also a whole suite of related services.
