The four control valve ranges have been certified by Exida for on/off operation within a SIL 3 safety instrumented function. The valves can be packaged with the already successful SIL 3 certified Fisher Fieldview DVC6000 SIS digital valve controller that enhances the safety function and monitors the health of the entire final control assembly. Only Fisher control valves offer the combined benefits of proven process control excellence and safety-certification to IEC 61508.

Fisher valves are components of Emerson's smart SIS safety management solution. The smart SIS solution enables customers to implement safer facilities, improve availability, lower life-cycle costs, and ease regulatory compliance.
