Metso has added a new valve design derived from its 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 optional two-way-tight feature covers the size range from DN25 up to DN700 (1” up to 28”) in all available pressure classes.
With numerous applications where two-way-tight, on-off type performance is required, the new V-port segment valve design offers the possibility of combining control and on/off performance in a single valve assembly. The standard bi-directional shut-off classifications of the V-port segment valves are according to 10x ISO Rate D / FCI 70.2 Class IV; optional improved tightness classes are ISO Rate D / FCI 70.2 Class V @ dp 20 bar.
