Neles Series X Trunnion Mounted Ball Valve

Brand: Valmet

Metso's Neles series X is a trunnion modular ball valve. 

Neles X series valves incorporate robust stem to ball connection. This assures valves are delivering solid long lasting performance in high cycle isolation and control applications. 

Application based seat selection assures valves are capable of delivering long lasting tightness even in most demanding applications including abrasive fluids and solids handling. 

Valve modularity widens the options in material selections to meet application specific requirements. 

Valves are also capable of delivering excellent control accuracy together with Metso Q-trim anti-cavitation and noise reduction trim technology. 

Valve series meets modern industry requirements concerning safety and emissions.
