Masoneilan SVI* II ESD Emergency Shutdown Device
The SVI II ESD can capture shutdown events, allow continuous HART communications during a trip, and facilitate local panel annunciation using the built-in discrete outputs. The SVI II ESD automatically captures the partial stroke test (PST) in its non-volatile memory and stores the analysis. Two signatures can be stored, allowing the ValVue* ESD Lookout stand-alone or integrated software to automatically and regularly synchronize its database with field data.
Features & Benefits
-
Emergency Shutdown function independent of partial stroke tests offers versatility in implementing partial stroke tests
-
User friendly setup and operations helps improve testing and valve maintenance efficiency and helps reduce installation costs
-
Universal design helps improve asset utilization
-
Testing methods facilitate safety regulation compliance and extends duration between full proof tests without disturbing process
-
Execution of ESD valve PST from any logic solver SIL3 while at 4mA offers efficient operation and ease of use
-
Captures shutdown events and confirms ESD operations for superior safety integrity level (SIL) of emergency isolation valve applications
