Emergency shut-down (ESD)

Metso's Neles ValvGuard VG9000 is a new generation intelligent safety solenoid with partial stroke testing features. It can be used both with emergency shutdown (ESD) and emergency venting (ESV) valves. With VG9000, plant safety can be increased due to extensive safety valve testing capabilities and improved diagnostics data.

Neles VG9000 features automatic Partial Stroke Test (PST), emergency trip test and internal pneumatics test. The safety valve condition can be constantly monitored with the diagnostics data gained from the performed tests. Extra instrumentation and parallel limit switch mounting are unnecessary, because Neles VG9000 has market leading pneumatics capacity and optional internal limit switches. VG9000 is available for FOUNDATION fieldbus and HART communication.
In addition to improved safety, VG9000 provides real-time alarm management without extra costs.
