Functional safety rating helps ensure that customers receive secure and reliable actuation in safety-critical environments


DALLAS, December 13, 2013 - Flowserve Corporation (NYSE: FLS), a leading provider of flow control products and services for the global infrastructure markets, today announced it received IEC 61508 SIL 2 and SIL 3 certifications for Flowserve Limitorque MXa electronic actuator optional output boards and arctic temperature components. This certification is in addition to the original SIL certification granted by exida® to the basic MXa in January 2012. Customers can combine the MXa actuator, which is certified to SIL 3, with any of the newly certified boards and components, and all SIL certifications will remain compliant to address arctic environments down to -60oC (-76°F). The MXa was designed for long service life in applications that require severe safety measures.

"Customers want assurances that the equipment they purchase for critical installations is safe," said Scott Mayo, vice president, sales and operations, Flow Control Operations, Power Sector. "The SIL certifications for the MXa and its add-ons, and the actuator's built-in safeguard features, reaffirm our commitment to systematic integrity and safety."  

Flowserve customers can order the MXa actuator with any combination of option boards, including network protocol field units like Modbus DDC, Foundation Fieldbus H1, Profibus DP and PA, and Device Net. Optional analog output board and digital output boards are included in the updated certification.  

In June 2012, the company announced availability of the MXa with capability up to a SIL 3 safety rating. Advantages of this certification include continued torque and position protection during a safety event, and the removal of external devices needed to track the actuator's position. Furthermore, the MXa is SIL certified independently of hardware modules, removing the risk for additional points of failure from the safety system.

SIL certification was granted based upon the MXa's reliable LimiGard(TM) technology which means that the user does not need to bypass connection to the actuator's internal relays to ensure sound actuator operation. The internal safeguard features of the MXa actuator are sufficient to report its status and to respond when an ESD is asserted.

For safe operation, no peripheral wiring is required to isolate the actuator from its internal programmable logic. Together, the MXa and its select option boards' Probability of Failure on Demand (PFD) values are the lowest in the electronic actuator industry.
