Wide range of Metso’s Neles flow control products receive SIL certifications

Metso’s customer can confidently apply the high performance flow control products they have become familiar with on the process side to critical safety applications as well.

Metso has certified several flow control products to help process industry end-users ensure that their plants comply with technical standard ‘IEC 61511, Safety Instrumented Systems (SIS), for the process industry sector.

Safety has always been an important and visible theme at Metso. Compliance with all applicable standards is top priority, as Metso is continuously improving the performance of all its products based on the field experience data collected from tens of thousands of units installed worldwide.

According to Timo Torvinen, VP, Energy & Hydrocarbon sales and marketing, Metso:
“In recent years, our customers, particularly in the energy and hydrocarbon industry, have been looking for standardized best-in-class valve and controller technologies that can be applied systematically both in process control and safety applications."

The following products can be used in safety loops requiring Safety Integrity Level SIL 3 classified automated on-off valves:
* Neles® X and D series ball valves
* Neles® L6  and Mapag® B-series butterfly valves
* Neles® B-series actuators
* Neles® ValvGuard VG9000 intelligent safety solenoid

In applications where a control valve can perform the safety action, the following products can be used in flow control loops requiring SIL classified control valves:
* Neles®  Finetrol eccentric rotary plug control valve
* Neles® ND9000 intelligent valve controller
Third party certificates are in accordance with the newest version of IEC 61508. Metso control and automated on-off valves provide complete solutions from a single source supplier and are tested as an assembly to assure compatibility of crucial safety loop components.

Furthermore, to improve use and servicing of critical safety loop components, Metso has introduced new safety manuals for their valve and actuator series. These provide the functional and safety-related information required to integrate and use valves in safety systems in accordance with the IEC 61508 standard.
