Finnish pulp and paper manufacturer Stora Enso is buying Metso's valves to convert its Varkaus Mill fine paper machine to lightweight containerboard.
Metso will supply Neles ball valves, V-port segment valves and triple-eccentric Neldisc butterfly valves for on-off and control applications at Stora Enso.
The company, which carried out an installed base audit of its valves in the recycled fiber plant, will also provide spare part inventory services to the mill.
Commenting on the partnership, Metso pulp and paper sales director Marko Lindeman said: "Stora Enso and Metso have a long-term relationship in the Varkaus Mill.
Metso has been providing its flow control solutions to Stora's plants.
Lindeman added: "In addition to the valve supply contract, the results of Metso's audit ensure that they can utilise the existing valve equipment in the containerboard machine, and the necessary maintenance measures can be foreseen and scheduled.
"Our spare part inventory services ensure that critical parts are available for them. This will bring cost savings and will ensure optimum process efficiency."
Upon completion of the upgrade, the containerboard machine will begin operations in the fourth quarter of 2015.
The financial terms of the order have not been disclosed.
Metso currently has more than 40 valve and field device service centres and offers on-off valves for pulp and paper customers across the world.
Metso's valve technology centres and valve production facilities are located in Finland, the US, Germany, China, South Korea, India and Brazil.
