Metso iESD – intelligent safety valves from a single manufacturer
Metso's reliable intelligent emergency shutdown (iESD) valves and actuators with Neles ValvGuard intelligent valve controllers improves your plant safety cost efficiently. In Metso iESD we have combined our know-how of valves, actuators, safety standards (IEC61508/61511), applications, system operability and partial stroke test devices with intelligent prediction tools. This all is put into single package and tested and configured as complete assembly with clear responsibility.
Improving availability with field proven reliability and advanced diagnostics
Metso iESD valves with periodic partial stroking provide increased availability and meet safety integrity even for extended plant uptimes and proof test intervals. Neles ValvGuard's advanced diagnostics gives more flexibility to testing intervals and verifies valves are field tested against various failures. Field proven, certified technology gives an accurate reliability figures and failure rates for final element in your safety loop. Final element's probability of failure on demand and optimal test intervals are estimated by Metso's
Nelprof valve selection tool.
Partner through safety life cycle
Metso's global sales and service network support you from engineering to commissioning and startup to end of life through safety life cycle of the iESD-valve.
The Metso ESD valve range consists of:
