Functional Safety Assessment of Valve Assemblies

Recording Date: January 2016

More and more devices that are used in safety critical systems are available with IEC 61508 certificates. This helps integrators and process owners move towards compliance with IEC 61511 and other functional safety standards. When looking at a valve assembly using certified devices is a good start but by itself doesn’t cover all requirements, there can still be unaddressed issues with engineering, design, and components. Engineering and design issues include the proper matching of actuators and valves, designing proper interfaces. Component issues include selecting appropriate brackets, couplings, and feedback switches. This webinar will investigate the steps required to ensure valve assemblies meet the requirements of IEC 61511 and IEC 61508 and provide a methodology to evaluate current and future designs.
