's offering of valves, actuators and intelligent valve controllers has been extended with the introduction of SIL certified ball valves.
Trunnion and seat supported modular ball valve series X and M are classified and certified by Lloyd's in accordance with IEC 61508, Type A equipment.
The SIL assessment study with field proven reliability analysis confirms that X and M series ball valves can be used in applications up to and including SIL 3 in single valve configurations in accordance with IEC 61508. Metso
's iESD (intelligent emergency shutdown
) valves and actuators with Neles ValvGuard intelligent valve controllers improve plant safety cost efficiently.
Metso's iESDs combine the know-how of final elements and applications, safety standards and system operability together with intelligent partial-stroke test devices. All this technology has been combined in a single package and tested and configured as an integrated assembly with a clear function.
