Liansheng and Neles™ valves: flow control excellence for the pulping and papermaking industry

Liansheng Pulp and Paper in China require the utmost precision and reliability in their production processes. That’s why they insist on using Valmet’s Neles™ flow control solutions throughout their entire mill.

What makes single rolling design peristaltic pumps the best solution when pumping abrasive slurries?

The superintendent of the water treatment plant was examining shoe designed peristaltic pumps and single rolling design peristaltic pumps. The customer was convinced that Flowrox's peristaltic pump with only one compression per 360 degree revolution will lead to at least 3-5 times longer hose life time than conventional hose pumps. After installation, the first hoses in the Flowrox pumps lasted approximately for 9 months - a great result with 11 million revolutions while pumping abrasive lime.

Merger of Valmet and Neles: Forward together from a stronger base

Over the years, Neles and its predecessors have developed capabilities that position us as a best-in-class player in our field. Now, we look forward to accelerating this agenda as part of Valmet. The key message to our customers is: our capabilities and know-how are even stronger. In fact, we are operating from a stronger base and with wider offering, covering more markets and leveraging our global reach in a more efficient manner.

The road ahead

Neles, nowadays part of Valmet, can pride itself on 65 years of experience in designing and manufacturing flow control solutions for various process sectors. Building on this foundation of knowledge, expertise and insights, the company is ready for the 21st century with exciting developments in renewable energies and more mature sectors such as oil and gas. One telling example is the revamped butterfly valve range that Neles recently introduced.

We talked with Kalle Suurpää about R&D and testing of our valve solutions.

Valve expertise secures Naantali power plant’s reliability

The power plant process involves challenging conditions, and the plant must remain on stream continuously. Control valves are a small but important part of the process: they control flow and keep the power plant’s process stable, helping to ensure that the plant operates efficiently. This is why Neles’ valves were chosen for Turun Seudun Energiantuotanto Oy’s (TSE) new power plant in Naantali, Finland.

Suzano advances towards Industry 4.0

The Imperatriz Unit in Maranhão has adopted a solution that predicts faults in high criticality processes and reduces downtime for automatic on-off type valves.

How to improve turbine efficiency

In the power and gas turbine market, competition among turbine and compressor manufacturers has become more challenging. Decisions are driven mainly by price and efficiency. Saving costs by selecting the correct application-based control and safety valves has become more important. New valve technologies and new valve designs help increase turbine efficiency and reduce costs while improving safety, for example, by installing a faster pressure relief in the case of a trip in a compressor or a gas turbine compressor.
