Hansen Technologies Corporation has issued a safety notice regarding pressure relief valves sold to its customers for industrial use between February 16, 2011 and April 4, 2013. The notice states that the valves “are more susceptible to internal corrosion when exposed to standing water inside the valve.” The failure of a pressure release valve could conceivably result in serious personal injury and/or property damage. Hansen has initiated a program to provide replacement valves so that any valves currently at risk can be replaced promptly. To date the company has not received any reports of valve failures that have resulted in personal injury or property damage. Hansen H5600A, H5601, H5602, H5600R, H5602R, and H5632R valves with serial numbers 02B11 through 04B13 are susceptible, regardless of pressure setting.
