ATI actuators are piston-style linear actuators used on control valves, gate valves and other rising stem valves. Recent projects have required further testing and increased reliability assurance. TUV Rheinland officially SIL-rated the actuators to Level 3 in August of this year and issued its FMEA report to ATI. View ATI’s TUV Rheinland-issued SIL report here.
This level rating confirms ATI actuators have a low probability of failure on the order of .001-.0001. This is important in high reliability applications where the device could cause severe consequences if it is not rated at this level or higher. ATI offers this level of rating as a standard on all its actuators whether it is needed or not.
