Metso has strengthened its product offering with the addition of a new valve design derived from the traditional V-port segment valve series. The new two way tight, single-seat design is suitable for a wide range of applications and is available for R-series valves. The two way tight feature covers the size range from DN25 up DN700 in all available pressure classes.
Cost-efficient shut off
With its V-port segment valve series, Metso was able to improve process performance and reduce variability in control applications. However, there are many applications where two way tight, on/off type performance is required and the benefit of the new valve design is that it offers the possibility of combining control and on/off performance in a single valve assembly.
Economical solution provider
One of Metso’s paper mill customers installed a DN 600 RE flanged, V-port segment valve in a steam discharge application. In this particular case, low-pressure, superheated steam flows through the two way tight valve at 200°C. A traditional valve solution for this application would have been a two way tight ball valve. However, by selecting the new V-port segment valve, the customer was able to save 50% on capital costs.
In pulp mills there are many applications where two way sealing is required, for example there are many such valves next to batch and continuous digesters. In the bleaching department, the on-off valve after the chemical mixer is typically quite large and can require the feature.
The two way tight option is available for both RA and RE valve series for all standard pressure classes and flange drillings. It is also available in all standard body materials. If there is a requirement for other materials, the local Metso sales office can assist.
