A history of valve technology in service of the pulp & paper industry

The pulp and paper industry has long been one of the proving grounds for flow control technologies. It has consistently pushed valve technology toward higher durability, tighter sealing, and greater operational reliability. Our first Neles™ valves were delivered for pulp and paper service some 70 years ago. 

The perfect match: Neles™ NDX™ 2.0 paired with our leading globe control valves

Our Neles NDX 2.0 intelligent valve controller paired with the right valve designed to deliver accurate and repeatable performance in control applications is truly an ideal combination. When paired with, for example one of our globe valves such as the Neles G and A series, the benefits are clear over the valve assembly’s entire lifecycle.

Flowrox™ slurry knife gate valves

Heavy duty slurry knife gate valve isolates flow even in the most demanding process conditions. The bi-directional flow tolerates backflow and elastomer sleeves on both sides of the gate provide tight shut off. Flowrox knife gate valve follows the concept of the ease of maintenance. The valve body is cast in one piece which eliminates the need for sealing between the body halves. Load distribution ring is integrated into the valve sleeves. The valve contains only two service parts; ring sleeves and secondary seal.

Flow control for continuous catalytic reforming

The catalytic reformer is central to refinery operations and success. The advent of continuous catalyst regeneration has made a constant, non-declining yield achievable but only under the right operating conditions.

Upgrading older process plant valves to the latest technology translates into energy savings and long-term reliability

We are often asked why we recommend upgrading older valves to the latest technology. We will examine how technological improvements deliver measurable results in terms of cost savings, sustainability and long-term reliability.

World-class valve automation for any valve

For many, the first thing that comes into mind when we mention the name Neles is valves. While we have decades of experience in manufacturing industry-leading valves, we also have decades of experience in automating them. And not just Neles™ and Jamesbury™ valves, but any valve by any major manufacturer.

Efficiency takes more than just valves

Process control efficiency often directly correlates to improved profitability and environmental performance.

Optimizing valve maintenance using condition analysis

Typically in shutdown situation the amount of valves to be maintained is limited in order to meet maintenance budget. Valve maintenance can be optimized by using condition analysis to focus maintenance actions to only devices needing attention.

Diamonds are created in high pressure – where reliability and trustworthiness count even more

With increasingly stringent requirements being placed on challenging industrial processes, customers are demanding ever more reliable valve solutions to make their operations safe, environmentally friendly and future-proof for new regulations. These requirements set high-level expectations on a long servicing interval for valves and minimized process downtime. They also lead to high-yield processes for customers.
