Valmet will supply pulp mill and board machine quality management solutions for Stora Enso's Varkaus Mill in Finland. The orders are an addition to the extensive rebuild of the Varkaus mill's PM 3 fine paper machine supplied by Valmet to produce lightweight containerboard grades announced on May 13, 2014.

The order was included in Valmet's second quarter 2015 orders received. The value of the order is not disclosed. Typically, the order value of automation system deliveries ranges from below EUR 1 million to EUR 3 million.

The Valmet delivery includes a Valmet Kappa Analyzer for the pulp mill and Valmet IQ quality control system (QCS) for the rebuilt board machine.
