Midland-ACS has announced that a wide range of its actuator control valve products have undergone third-party assessment to the IEC 61508 functional safety standard, and are now certified to support SIL (safety integrity level) 3 capability. Control valves with this high level of safety integrity are increasingly being specified by process industries to protect personnel and plant, by ensuring fail-safe operation of critical functions such as emergency shutdown.

By using SIL3 capable stainless steel valves and actuation controls enables compliance with the risk reduction requirements of the IEC 61508 and 61511 technical safety standards.

James Kingham of Midland-ACS says “Obtaining SIL3 capability certification for such a broad range of products is a considerable accolade for Midland-ACS, and we are already submitting low service temperature poppet and spool valves, along with further hydraulic products, for assessment.”

All Midland-ACS products certified to SIL3 capability are supplied complete with copies of the Sira certification, which contains all the information needed to calculate the safety integrity level of the complete system, based on its component parts.
