Soft-seated valves

Metso's iESD (intelligent emergency shutdown) valve offering has been extended with SIL3 certification for Jamesbury floating and trunnion soft-seated ball valves as well as SIL2 certification for soft-seated butterfly valves by TÜV Rheinland. In addition, the rack and pinion actuator VPVL series has received SIL3 certification. The SIL assessment study and field-proven reliability analysis confirm the usability of 4000, 7000 and 9000 series ball valves and actuators as final elements in safety instrumented functions for applications up to and including SIL3, in single-valve configurations, in accordance with IEC 61508. In addition, Wafer-Sphere butterfly valves and actuators have been confirmed for use in up to and including SIL2 in single-valve configurations in accordance with IEC61508.
